3D View of San Andreas Fault – Earthtopomaps 3D overlay imagery

Earth’s crust is a collection of fractured plates that shift across the planet’s surface over millions of years. Two of the major plates meet at the coast of California:. The Pacific Plate:. Under the ocean, is drifting slowly northwest:. Grinding along the margin of the North American Plate, to the east. Where they meet, the intense pressure of the collision creates an 800-mile-long fracture zone called the San Andreas Fault.

Much of the length of the fault is lined by a distinct trough. This false-color NASA radar image shows a section of the fault west of San Francisco Bay;. The Crystal Springs Reservoir fills the trough that marks the underlying fault. The black line curving along the east side of the fault is I-280:. And California highway 92 runs from the top right across to the center left of the image:. Heading towards Half Moon Bay to the west. San Mateo and Burlingame are parts of the large urbanized area in various tones of pink and green:. And Foster City is the area of curved streets extending out into the San Francisco Bay at the top right.

The image was captured in November 2008 as part of a campaign to repeatedly collect detailed:. Three-dimensional images of the San Andreas Fault along the same flight path.

The goal is to map which parts of the fault are creeping past each other with little “stickiness,”:. And which parts appear to be locked together places where pent-up stress may be released suddenly in a major earthquake:. By repeatedly collecting images over an identical flight track, scientists can spot places where the topography is visibly deformed.

Ground deformation sometimes just a fraction of inch can indicate that far below the surface, the plates are stuck together.

The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake:. Then up the San Francisco Peninsula:. Where it was first identified by Professor Lawson in 1895:. Then offshore at Daly City near Mussel Rock. (In this region around the San Francisco Bay Area several significant “sister faults” run more-or-less parallel:. And each of these can create significantly destructive earthquakes.):. After that, it runs underwater along the coast until it nears Cape Mendocino:. Where it begins to bend to the west, terminating at the Mendocino Triple Junction.

Early years

Eleven years later, Lawson discovered that the San Andreas Fault stretched southward into southern California after reviewing the effects of the 1906 San Francisco earthquake. This idea, which was considered radical at the time:. Has since been vindicated by modern plate tectonics.

Seismologists discovered that the San Andreas Fault near Parkfield in central California consistently produces a magnitude 6.0 earthquake approximately once every 22 years. Following recorded seismic events in 1857,. 1881,. 1901,. 1922,. 1934,. and 1966,. scientists predicted that another earthquake should occur in Parkfield in 1993. It eventually occurred in 2004. Due to the frequency of predictable activity, Parkfield has become one of the most important areas in the world for large earthquake research.

A 2023 study found a link between the water level in Lake Cahuilla (now the Salton Sea) and seismic activity along the southern San Andreas Fault.

The study suggests that major earthquakes along this section of the fault coincided with high water levels in the lake. The hydrological load caused by high water levels can more than double the stress on the southern San Andreas Fault, which is likely sufficient for triggering earthquakes. This may explain the abnormally long period of time since the last major earthquake in the region since the lake has dried up.

Cascadia connection

A 2008 paper, studying past earthquakes along the Pacific coastal zone, found a correlation in time between seismic events on the northern San Andreas Fault and the southern part of the Cascadia subduction zone (which stretches from Vancouver Island to northern California). Scientists believe quakes on the Cascadia subduction zone may have triggered most of the major quakes on the northern San Andreas within the past 3,000 years. The evidence also shows the rupture direction going from north to south in each of these time-correlated events.

Formation:

The San Andreas began to form in the mid Cenozoic about 30 Mya (million years ago). At this time, a spreading center between the Pacific Plate and the Farallon Plate (which is now mostly subducted, with remnants including the Juan de Fuca Plate, Rivera Plate, Cocos Plate, and the Nazca Plate) was beginning to reach the subduction zone off the western coast of North America. As the relative motion between the Pacific and North American Plates was different from the relative motion between the Farallon and North.

Google recently unveiled a new feature, “Waterways from Earth,” on Google Earth. The program relies on NASA and NOAA images to show our dynamic planet’s waterways from space. Here’s more about the science and stories behind those images.

Google Earth Pro ways that are visible even from space

Remote Rupert Bay in northern Quebec is a place where the majesty and dynamism of fluid dynamics is on display. With several rivers pouring into this nook of James Bay, the collision of river and seawater combines with the churn of tides and the motion of currents to make swirls of colorful fluid that could impress even the most jaded of baristas.

NASA’s Earth Observing-1 satellite captured this natural-color image of South Keeling Islands in 2009. Coral atolls which are largely composed of huge colonies of tiny animals such as cnidaria form around islands. After the islands sink, the coral remains, generally forming complete or partial rings. Only some parts of South Keeling Islands still stand above the water surface. In the north, the ocean overtops the coral.

Storm stirs sediment

Overlay satellite images in Google Earth Pro 2025

Category 3 Hurricane Gonzalo passed over Bermuda in 2014, stirring up sediment in the shallow bays and lagoons around the island and spreading a huge mass of sediment across the North Atlantic Ocean.

Stores of calcium carbonate sediments are moved from the shallows to the deep ocean by storms or density flows.

Storm-induced export of carbonate sediments into the deep ocean where they mostly dissolve is a significant process in the ocean’s carbonate and carbon cycles. It’s also important for the eventual neutralization of excess carbon dioxide entering the oceans because of increasing atmospheric CO2 concentrations from fossil fuel combustion.

The Gulf Stream in infrared

The Gulf Stream is an important part of the global ocean conveyor belt that moves water. And heat across the North Atlantic from the equator toward the poles. Stretching from tropical Florida to the doorstep of Europe. This river of water carries a lot of heat, salt and history. It is one of the strongest currents on Earth, and one of the most studied.

This image shows a small portion of the Gulf Stream about 300 miles (500 kilometers) east of Charleston. South Carolina, in infrared.

“Infrared bands measure how much energy is emitted by the surface of the Earth at particular wavelengths,” said:. Matthew Montanaro, a researcher on NASA’s Landsat team. “We can calculate the surface temperature from these measurements through math and some modeling. Essentially, the higher the infrared signal measured, the higher temperature on the surface.”

Waves beneath waves

This photograph, taken in 2013 from the International Space Station (ISS). Shows the north coast of Trinidad and a series of subtle, interacting arcs in the southeastern Caribbean. These are known as “internal waves,” the surface manifestation of slow waves that move well beneath the surface. Internal waves produce enough of an effect on the sea surface to be seen from space, but only where they are enhanced due to sunglint, or reflection of sunlight, back toward the Space Station.

Land of lakes

During the last Ice Age, nearly all of Canada was covered by massive ice sheets. Thousands of years later, the landscape of Nunavut Territory “our land” in the Inuktitut language – still shows the scars. Surfaces that were scoured by retreating ice and then flooded by Arctic seas are now dotted with millions of lakes, ponds and streams.

This area is frequently referred to as “Barren Grounds” because the soil remains frozen for much of the year, limiting the growth of trees and agriculture. However, looking beyond the “visible” spectrum reveals details from space. This false-color image from our Terra satellite shows vegetation in red, showing that during the summer thaw there is plenty of plant life in the form of lichens, mosses, shrubs and grasses.

Axel Heiberg Island Nunavut Arctic Canada – Earth topo maps

Axel Heiberg Island Nunavut Arctic Canada – Earthtopomaps

Axel Heiberg Island is located in the Arctic Ocean ( Nunavut, Canada ). It has a total area of 43178 km2 ( 16671 mi2 ). Ranking it the world’s 31st largest and Canada’s 7th largest island.

The island is famous for its fossil forest:.

( A former high-latitude wetland forest with tall trees ) dating back from the Eocene era:. ( 56 to 34 million years ago ). Due to the lack of mineralization in the specimens, the forests’ fossilization is more like mummification. The island’s warm climate allowed its trees to reach heights of up to 35 m ( 115 ft. ):. And age between 500 – 1000 years.

In summer 1986, a Canadian expedition started the fossil forest’s investigation. In 1999 started a project for the preservation of the fossil wood since due to erosion many of the fossils were already exposed and damaged.

Axel Heiberg Island Nunavut Arctic Canada – Earthtopomaps

There were even concerns that some of the fossils were being taken by cruise ship tourists:. And that the island was being disturbed by military helicopters from a nearby Canadian base.

Currently, there is a plan for establishing the Napaaqtulik National Park, which name in Inuit means ” where there are trees “. Along with the tree fossils. On Axel Heiberg Island were also discovered remarkably preserved animal fossils:. Including an Aurorachelys turtle from the Cretaceous period ( from 145 – 66 million years ago ).

Glaciation

White Glacier is a valley glacier occupying 38.7 km2 (14.9 sq mi) in the Expedition Fiord area of Axel Heiberg Island ( 79°30′N 090°50′W ). It extends in elevation from 56 to 1,782 m ( 184 to 5,846 ft ) above sea level. A range which, as noted by Dyurgerov (2002):. Is exceeded only by Devon Ice Cap in the world list of glaciers with measured mass balance. Ice thickness reaches or exceeds 400 m (1,300 ft).

Axel Heiberg Island Nunavut Arctic Canada – Earthtopomaps

Its maximum extension in recent history:. Marking the advance of the glacier in response to the cooling of the Little Ice Age and more probably at the beginning of the 20th century.

There is evidence that the retreat of the terminus, previously at about 5 m (16 ft) per year, is decelerating (Cogley et al. 1996a; Cogley and Adams 2000). White Glacier has been the subject of many papers in the glaciological literature since 1960, e.g. Müller ( 1962 ) was the source of a now-classical diagram elaborating and illustrating the concept of “glacier facies”.

Earthtopomaps – Cape Verde Archipelago the island chain – 3D

Earthtopomaps – Cape Verde Archipelago the island chain

Despite the islands’ varied appearances, geologists surmise that all of the islands are volcanic in origin, sitting over a hotspot where magma pushes up through the Earth’s crust and erupts on the sea floor.

The island chain includes a variety of terrain and vegetation. On islands in the east Boa Vista and its neighbors earth tones predominate. These islands are generally flat with little fresh water. In the west, more mountainous islands boast more abundant greenery.

The highest point in Cape Verde is in the southwest: the volcanic summit of  Fogo at 2,829 meters (9,281 feet).

The Cape Verde Archipelago lies some 650 kilometers (400 miles) off the coast of Senegal.

Against a navy background, the brown and green islands roughly form the shape of a giant V turned on its side.

Probably the best-known example of a hotspot is Hawaii. On a fast-moving plate, the Hawaiian Islands show a clear linear progression in age, with old Kauai in the northwest and young Hawaii ( Big Island ) in the southeast. Cape Verde, however, is roughly stationary with respect to the mantle plume responsible for its growth. As a result, the ages of the islands lack the same clarity as in Hawaii. In general:. Cape Verde islands appear oldest in the east ( Boa Vista and its neighbors ) and youngest in the northwest and southwest.

Earthtopomaps – Cape Verde Archipelago the island chain

Volcanic activity is not the only force shaping Cape Verde. Just as magma elevates landmasses, relentless winds grind them down. Winds blow often over Cape Verde, and the winds frequently carry heavy loads of Saharan dust. Wind erosion may be more apparent along the islands from Boa Vista to Santo Antão, which bear the brunt of Saharan winds.

Earthtopomaps – Tiny Beetles Take a Large Bite Out of Forest

) Earthtopomaps – Tiny Beetles Take a Large Bite Out of Forest

A single pine bark beetle is about the size of a grain of rice. But when the beetle population swells, it can have a major impact on forest health. And that’s exactly what has been happening across the Rocky Mountains over the past decade.

In Colorado, severe beetle infestations showed up in lodgepole pine forests about 50 miles west of Boulder and Fort Collins around 2000.

Over time, the affected area grew so that by 2011 the infestation had spread east to ponderosa pine forests that were much closer to the two cities. (A map showing the progression between 1998 and 2011 is available here).

The beetle epidemic caused so many trees to die-off that the impacts are visible from space. The Thematic Mapper on Landsat 5 acquired these images of lodgepole pine forests near Grand Lake, Colorado on September 11, 2005, and September 28, 2011 before and after a severe infestation led to die-off of the tree canopy.

Over six years, beetle activity turned entire ridges and valleys brown.

Forest die-off is most visible in the center of the image and along both sides of the Kawuneeche Valley. The brownest areas in the 2011 image are generally stands of lodgepole pine, a slender tree that grows at 6,000 to 11,000 feet (1,800 to 3,300 meters) in elevation. Either spruce or aspen dominates the green areas that escaped infestation:. Such as the forests near Gravel Mountain and areas west of the Kawuneeche Valley.

It has been suggested that all the dead needles and trees trunk left after a beetle infestation must make wildfires more common and severe.

It wasn’t uncommon for beetles to get the blame for exacerbating the destructive High Park fire that raged near Fort Collin in June 2012.

However, Bill Romme, a Colorado State University professor who has studied the relationship:. Is not convinced. “Most research indicates that there is little or no such relationship between beetle-caused tree mortality and subsequent fire occurrence and severity in lodgepole pine forests,” he noted in an email. “Fire occurrence and severity in these forests are controlled primarily by weather conditions. Variation in fuel conditions, such as that introduced by the beetles, is a secondary and generally minor influence on fire behavior.”

Not all of the browning is due to beetles. In the upper central and lower right of the image:. Logging has also had an impact. And despite the beetle damage to the upper canopy, the forests are anything but dead. Even in the most severely affected areas:. Large numbers of trees survive.

F) Earthtopomaps – Tiny Beetles Take a Large Bite Out of Forest

Researchers do think pine beetles can affect the risk of severe fires, but the impacts are not always straightforward.

The most dangerous fires crown fires leap from treetop to treetop in an explosive wall of flame:. Rather than creeping along the ground surface. For the first few years after an infestation:. Beetle-impacted forests may have an increased risk of crown fires due to the dry needles that remain clinging to the tops of dying trees. But as these needles and other debris drop to the ground:. The risk of crown fires drops as well. According to one study, forest die-off from pine beetles infestations can reduce the risk of crown fires for decades by thinning forests.

Which layers shows the presence of aurora borealis ?

The thermosphere’s temperature is greatly influenced by solar activity. Finally, the thermosphere is where the aurora ( Southern and Northern Lights ) occur. At high latitudes, charged particles from space clash with atoms and molecules in the thermosphere, causing them to be excited into higher energy levels.

Where on Earth can you see the aurora borealis ?

( Google Earth Pro ): So current datasets might classify a satellite image of a city as ‘built-up,’. But visit any city and you’ll see our world is far more dynamic. While you might see lots of buildings. You’ll also see trees or even snow on the ground from a recent storm.
Manage and restore land and monitor the effectiveness of those plans using alert systems to notify when unforeseen land changes are taking place.
Not only is our world more dynamic than individual land types it’s also constantly changing.
This means that not only is the land cover information in Dynamic World more detailed. But it’s also more timely within any given day. Week or month than existing datasets. This level of detail allows scientists and policymakers to detect and quantify the extent of recent events anywhere on the globe such as snowstorms, wildfires or volcanic eruptions within days.

Earthtopomaps – Landslide Buries Valley of the Geysers – Earth

Earthtopomaps – Landslide Buries Valley of the Geysers – Earth

Geysers are a rare natural phenomena found only in a few places:. Such as New Zealand, Iceland, The United States ( Yellowstone National Park ):. And on Russia’s far eastern Kamchatka Peninsula. On June 3, 2007, one of these rare geyser fields was severely damaged when a landslide rolled through:. Russia’s Valley of the Geysers. The landslide a mix of mud, melting snow, trees:. And boulders tore a scar on the land and buried a number of geysers:. Thermal pools, and waterfalls in the valley. It also blocked the Geyser River, causing a new thermal lake to pool upstream.

The Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER ) on:. NASA’s Terra satellite captured this infrared-enhanced image on June 11, 2007, a week after the slide.

Large Image: 8192 X 4709 ( click on the image to enlarge )

The image shows the valley, the landslide, and the new thermal lake. Even in mid-June, just days from the start of summer, the landscape is generally covered in snow:. Though the geologically heated valley is relatively snow free. The tree-covered hills are red (the color of vegetation in this false-color treatment):. Providing a strong contrast to the aquamarine water and the gray-brown slide. According to the Russian News and Information Agency ( RIA ) [English language], the slide left a path roughly a kilometer and a half ( one mile ) long and 200 meters ( 600 feet ) wide.

Within hours of the landslide, the water in the new lake inundated a number of additional geysers.

The geysers directly buried under the landslide now lie under as much as 60 meters:. (180 feet) of material, according to RIA reports. It is unlikely that the geysers will be able to force a new opening through this thick layer, adds RIA. Among those directly buried is Pervenets (Firstborn), the first geyser found in the valley, in 1941. Other geysers, such as the Bolshoi ( Greater ):. And Maly ( Lesser ) Geysers, were silenced when buried by water building up behind the new natural dam.

Earthtopomaps – Landslide Buries Valley of the Geysers

According to Vladimir and Andrei Leonov of the Russian Federation Institute of Volcanology and Seismology:. The new lake appears to be stable and draining gradually through the earthen dam, alleviating fears of a catastrophic flood.

Should the new lake drain enough, many of the inundated geysers may restart. Initial reports from the Volcanology and Seismology Institute state this has already happened for some geysers. Geysers outside of the slide region, including the Velikan:. (Giant) Geyser and a major section of the geyser field known as Vitrazh (Stained Glass) appear to have escaped damage.

Earthtopomaps – Landslide Buries Valley of the Geysers – Earth

In addition to destroying a number of geysers, the landslide may have damaged habitats in the Valley of the Geysers. The thermal waters and heated steam jets made this valley warmer than the surrounding landscape:. And the warmth supported a unique ecosystem. The loss of a large part of its heat source may alter the ecosystem:. But it is not clear what additional longer-term changes might occur. For example, salmon that spawn in the:.

Eruption of Sarychev Peak, Kuril Islands

The event left behind a changed island. Acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite, these images of Ostrov Matua show the island shortly after the eruption on June 30, 2009 (top), and two years before on May 26, 2007.

In these false-color images, vegetation appears red, water appears dark blue, and clouds, water vapor and ice all appear white.

Volcanic rock, including old lava flows and debris from the recent eruption, ranges from gray to dark brown.

The most striking difference between these two images is the gray coating on the northwestern half of the island in June 2009. While vegetation on the rest of the island appears lush, volcanic debris probably a mixture of pyroclastic flows and settled ash covered virtually all the vegetation on the northwestern.

A close look at the top image also reveals that the recent volcanic activity appears to have expanded the island’s coastline on the northwestern end.

Another difference between the images relates to snow cover. In the image from May 2007, snow spreads over much of the island, although the snow alternates with snow-free ground. The vegetation is pinkish-gray, suggesting the spring thaw is still underway. The complete lack of snow in 2009 may result from a combination of a difference in season and volcanic activity having melted:. Or covered any lingering snow.

Eruption of Sarychev Peak 2023
Eruption of Sarychev Peak 2023

A fortuitous orbit of the International Space Station allowed the astronauts this striking view of:. Sarychev Volcano (Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009. Sarychev Peak is one of the most active volcanoes in the Kuril Island chain:. And it is located on the northwestern end of Matua Island. Prior to June 12, the last explosive eruption occurred in 1989, with eruptions in 1986, 1976, 1954, and 1946 also producing lava flows. Ash from the multi-day eruption has been detected 2,407 kilometers east-southeast and 926 kilometers west-northwest of the volcano: and commercial airline flights are being diverted away from the region to minimize the danger of engine failures from ash intake.

This detailed astronaut photograph is exciting to volcanologists because it captures several phenomena that occur during the earliest stages of an explosive volcanic eruption.

The main column is one of a series of plumes that rose above Matua Island on June 12. The plume appears to be a combination of brown ash and white steam. The vigorously rising plume gives the steam a bubble-like appearance.**

In contrast, the smooth white cloud on top may be water condensation that resulted from rapid rising and cooling of the air mass above the ash column. This cloud, which meteorologists call:. Is probably a transient feature: the eruption plume is starting to punch through. The structure also indicates that little to no shearing wind was present at the time to disrupt the plume. (Satellite images acquired 2-3 days after the start of activity illustrate the effect of shearing winds:. On the spread of the ash plumes across the Pacific Ocean.)

By contrast, a cloud of denser:. Gray ash probably pyroclastic flow appears to be hugging the ground, descending from the volcano summit. The rising eruption plume casts a shadow to the northwest of the island (image top). Brown ash at a lower altitude of the atmosphere spreads out above the ground at image lower left. Low-level stratus clouds approach Matua Island from the east, wrapping around the lower slopes of the volcano. Only about 1.5 kilometers of the coastline of Matua Island (image lower center) are visible beneath the clouds and ash.

Editor’s note: Following the publication of this photograph:. The atmospheric and volcanic features it captured generated debate among meteorologists, geoscientists, and volcanologists who viewed it.

Post-publication, scientists have proposed and disagreed about—three possible explanations for the hole in the cloud deck above the volcano.

Eruption of Sarychev Peak 2020 to 2023
Eruption of Sarychev Peak 2020 to 2023

One explanation is that the hole in the clouds has nothing to do with the eruption at all.

In places where islands are surrounded by oceans with cool surface temperatures:. It is common for a sheet of clouds to form and drift with the low-level winds. When the cloud layer encounters an island, the moist air closer to the surface is forced upward. Because the air above the marine layer is dry, the clouds evaporate, leaving a hole in the cloud deck. These openings, or wakes:. In the clouds can extend far downwind of the island, sometimes wrapping into swirling eddies called von Karman vortices.

One is that the shockwave from the eruption shoved up the overlying atmosphere and disturbed the cloud deck:. Either making a hole or widening an existing opening. The final possibility is that as the plume rises:. Air flows down around the sides like water flowing off the back of a surfacing dolphin.

As air sinks, it tends to warm; clouds in the air evaporate.

Earthtopomaps – Fires Burn Across Quebec, Canada

Earthtopomaps – Fires Burn Across Quebec, Canada

An unusually intense start to Canada’s wildfire season filled skies with smoke in May 2023.

Then, at the beginning of June, scores of new fires raged in the eastern:. Canadian province of Quebec, some of which were ignited by lightning.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this view of smoke billowing from the fires on June 3. Shortly after the fires started:. About 5,000 residents were ordered to evacuate near the city of Sept-Îles in the province’s east. As the fires grew:. Evacuations were extended to an additional 9,000 people in surrounding communities and in western Quebec’s Val-d’Or and Normétal municipalities. As of June 5, more than 150 wildfires were active in Quebec.

Smoke from the blazes prompted air quality warnings across Quebec and Ontario. On June 4, the air quality index for fine particulate matter (PM 2.5):. Was classified as unhealthy in southern Quebec and eastern Ontario:. According to NOAA’s Aerosol Watch. Fine particulate matter from the smoke blew down to the U.S. Midwest, where it made the air quality unhealthy for sensitive groups in parts of Minnesota, Wisconsin, Illinois, and Michigan.

Fire season in Quebec usually starts in late May. In an average year, only 247 hectares (a square mile) of area would be burned by June 5,:. According to Quebec’s fire prevention agency (SOPFEU). But so far this year, 160,000 hectares (600 square miles) have burned.

width: 2466px, height: 1644px

The fire prevention agency said the fierce start to the season has in part been due to:. High temperatures and dry conditions in the province.

A Smoky May for North America

For remote sensing scientists who track the movement of smoke plumes:. May 2023 has been a wild, memorable month due to extreme fire activity in northwestern Canada.

Early spring always brings elevated fire risk to Alberta, Saskatchewan, and the northeastern edge of:. British Columbia naturally dry areas that lie in the rain shadow of the Canadian Rockies. There is a period each year, after snow melts but before spring growth begins, that dry forest undergrowth is exposed.

But in May 2023:. This naturally fire-prone dry period coincided with unusually hot:. And windy weather, turning what normally would have been small:. Short-lived fires into huge wildland blazes that raged for several weeks. The fires, ignited by lightning or human activity, charred more than 1 million hectares:. (400 square miles) as of May 24, and lofted smoke high into the atmosphere and across North America.

The animation above highlights the volume of smoke and its dynamic, swirling movements between May 5-22, 2023. It shows black carbon particles commonly called soot—moving across North American skies during that period. The black carbon data come from NASA’s GEOS forward processing (GEOS-FP) model:. Which assimilates data from satellite, aircraft, and ground-based observing systems. In addition to making use of satellite observations of aerosols and fires:. GEOS-FP also incorporates meteorological data like air temperature, moisture, and winds to project the plume’s behavior.

Over the course of the fire outbreak:. Large rivers of smoke traced meanders in the jet stream, swirled into two separate extratropical cyclones:. And darkened skies across large swaths of North America for weeks.

Scientists even used satellites to track smoke injected high into the atmosphere by:. Canadian wildfires early in the month as it circled the entire globe.

“None of this is unprecedented,” said Michael Fromm, a meteorologist at the U.S. Naval Research Laboratory who has observed the dynamics of smoke plumes with colleagues from NOAA, NASA:. And several other science institutions for decades. “We have seen smoke from this region behave like this in the past,” he said. “But the amount of smoke is unusual for this time of year.”

Earthtopomaps – Water Levels in Lake Powell – 3D Model

Earthtopomaps – Water Levels in Lake Powell

In the 1950s, construction began on the Glen Canyon Dam on the Colorado River in northern Arizona. The dam created Lake Powell: a long, skinny, meandering reservoir straddling the Arizona-Utah border. Ingenuity of human design, however, did not protect this massive reservoir from the drought that struck much of the southwestern United States between 2000 and 2007.

The graph shows Lake Powell’s water level from 2000 to 2007, measured in millions of acre-feet.

This measure of lake volume counts the acres of land surface covered by a foot of water. The water level from May 2006, superimposed onto the satellite image, had actually rebounded somewhat from the 2005 low. After peaking in late 2000 with more than 20 million acre-feet, the reservoir’s water level sharply declined to roughly 8 million in mid-2005.

C) Lake Powell is the second-largest artificial reservoir in the United States, after Lake Mead.

D) Controversy courted the Glen Canyon Dam from the time of its construction in the 1950s.

Although the dam provided a reliable water source for millions of Americans, rising waters obscured the geology and archeology of the Glen Canyon, and caused the extinction of Grand Canyon fish species downstream. For admirers Glen Canyon geology, however, the 2005 drought had an upside; dropping water levels revealed some of the local geology.

Earthtopomaps – Mangroves and Coral Reefs, Viti Levu, Fiji – 3D

Earthtopomaps – Mangroves and Coral Reefs, Viti Levu, Fiji

Deep green forest on land. And the delicate turquoise coral reef in the ocean mirror each other in this true-color image from December 18, 2009. Both systems provide a significant habitat for a wide range of life. And both depend on the other for their healthy existence.

The forest, a mangove forest. Defines the delta of the Ba River on the north side of Viti Levu, Fiji’s main island.

Such mangrove forests serve as the interface between river and sea across:. Fiji and in many other places in the world. The trees grow with roots submerged in the semi-salty water near the shore. But they grow best in sheltered areas, where the ocean’s battering waves are minimal. In this case, the coral reef offshore provides a break, slowing incoming waves.

The mangrove forest, in turn, protects the reef from sediment and extensive algal blooms.

The tangle of roots catches sediment and nitrogen from the river, acting as a natural filter. Sediment would cloud the water, blocking the sunlight that the coral needs to grow. Nitrogen from agricultural run-off feeds algae in the ocean. Extensive ocean blooms can coat the reef or rob the water of oxygen. Both of which would be harmful to the reef. Nitrogen run-off could be a problem along the Ba River. Since the river flows through heavily farmed hills and valleys where most of Fiji’s sugar cane is produced.

But July 21, 2011, offered up a perfectly cloud-free view.

Also called the Great Sea Reef, Cakaulevu shines turquoise through clear, shallow waters. It is the third longest continuous barrier reef in the world:. Behind the Great Barrier Reef in Australia and the Mesoamerica Reef off Central America. When combined with the nearby Pascoe Reef, Cakaulevu Reef is about 200 kilometers (120 miles) long. On its own, the Cakaulevu Reef covers 202,700 square kilometers (77,200 square miles).

The first systematic survey of the reef (in 2004) revealed a diverse marine population:. Including unique mangrove ecosystems and endemic fish. Twelve threatened species live within the reef: 10 fish species, the green turtle, and the spinner dolphin.

All of this marine life has traditionally supported the native population, and currently some 70,000 people depend on the reef.

After seeing fish populations decline in recent decades:. Local leaders created a series of marine protected areas in 2005 where fishing is prohibited. Traditional customs used to manage the reef for hundreds of years permit leaders to set aside portions of the qoliqoli:. Or traditional fishing ground. Where the ban has been enforced, fish populations are rebounding and spilling over into areas where fishing is permitted.

This false-color image shows the gradual conversion of forest lands for agricultural use in the Tierras Bajas region of Santa Cruz, Bolivia, as observed by the Thematic Mapper (TM) flying aboard Landsat 5.

Earthtopomaps – Deforestation in Tierras Bajas, Bolivia

Forest and woodland are represented as grey tones from Channel 5 in this TM scene, collected in 1998. Other colors indicate the first year in which a site was developed for agriculture:. (See color scale in the image:. Which corresponds to years of development).

In this scene, land use types are delineated with lines. Solid white lines show the locations of planned colonies, dashed white lines show spontaneous colonies:.

And dotted white lines show Mennonite colonies. All other regions of development are non-Mennonite industrial soybean farms.

Natural vegetation formations in this image are delineated with black lines. Solid black lines show the locations of Northern Chaco Woodlands and dashed black lines show Cerrado regions.

For more information, see this previous Image of the Day regarding Bolivian deforestation.

This image from Landsat7, acquired on August 1, 2000, shows the new agricultural settlements east of Santa Cruz de la Sierra, Bolivia in an area of tropical dry forest.

Since the mid-1980s, this region has been rapidly deforested as a result of the resettlement of people from the Altiplano (the Andean high plains) and a large agricultural development effort, called the Tierras Baja project. The pie or radial patterned fields (left) are part of the San Javier resettlement scheme. At the center of each unit is a small community including a church, bar/cafe, school, and soccer field-the essentials of life in rural Bolivia. The rectilinear, light-colored areas (right) are fields of soybeans cultivated for export that are mostly funded by foreign loans. The dark strips running through these fields are wind breaks. These are advantageous because the soils in this area are fine and prone to wind erosion.

Earth – 30th Anniversary of the Eruption of Mt. St. Helens

Earth – 30th Anniversary of the Eruption of Mt. St. Helens

(Earthtopomaps – 30th Anniversary). 12 1978

(Earthtopomaps – 30th Anniversary). 03 1980

In mid-March 1980, a series of small earthquakes began shaking the ground at Mt. St. Helens in southern Washington.

Over the next two months, the northern flank of the mountain was deformed by a large bulge a sign that upwelling magma was pushing up on the rock from below. On the morning of May 18, an earthquake caused the entire north flank of the volcano to collapse in a massive avalanche. Relieved of the overlying pressure, the volcano ejected a blast of rocks, ash, gas, and steam that blew down and buried several hundred square miles of forest.

) Earth – 30th Anniversary of the Eruption of Mt. St. Helens

This trio of false-color Landsat satellite images is part of a 30-year time series documenting the destruction and recovery at Mt. St. Helens.

Earthtopomaps - 30th Anniversary

) Earth – 30th Anniversary). August 29, 1979

Vegetation is red, bare rock and volcanic debris are gray, and clear water is dark blue. (In the complete time series, images from 1984 onward are in photo-like natural color.) The 1979 view (top) shows the snow-covered summit of the perfectly shaped stratovolcano, and the mixture of forest types surrounding the mountain. The darkest red areas are likely undisturbed forests (e.g., north of the volcano), while to the east is a patchwork of forest and logging clear cuts. Lighter red vegetation northwest and west of the volcano are probably tree plantations.

(Earthtopomaps – 30th Anniversary). September 24, 1980

The image from September 24, 1980 (middle), shows the devastation of the May 18 eruption.

The northern flank of the mountain collapsed, producing the largest landslide in recorded history. The avalanche buried 14 miles (23 kilometers) of the North Fork Toutle River with an average of 150 feet (46 meters)—but in places up to 600 feet (180 meters)—of rocks, dirt, and trees. The blast spread rock and ash (gray in the images) over 230 square miles (600 square kilometers). A raft of dead trees floats across Spirit Lake. Volcanic mudflows (lahars) poured down rivers and gullies around the intact flanks.

Large Image: 8192 X 4006 ( click on the image to enlarge )

Earthtopomaps - 30th Anniversary

Three decades later, the image from September 10, 2009, shows the recovery in the blast zone. Most of the landscape within the blast zone has at least a tinge of red, meaning vegetation has recolonized the ground. The flanks of the volcano itself are still bare, as is a broad expanse north of the volcano called the Pumice Plain.

Directly in the path of the landslide and several pyroclastic flows, this area has been slowest to recover.

Ground surveys, however, have found even this seemingly barren area is coming back to life: the first plant to re-appear was a prairie lupine, which can take nitrogen—a critical plant nutrient—straight from the air rather than from the soil. These small wildflowers begin the crucial task of rebuilding the soil and attracting insects and herbivores. This process is underway on the Pumice Plain, even though it is not yet visible from space.

Located near the east coast of Italy’s province of Sicily, Mount Etna is Europe’s most active volcano. And is one of the world’s largest continental volcanoes, standing about 3,350 m (10,991 feet) tall. Mount Etna has a broad base (or shield) spanning roughly 60 by 40 km (36 by 24 miles). And reaching an altitude of about 2,900 m (9,500 feet). The remaining 400 m (1,200 feet) at its top is a stratovolcano made from several vents that have coalesced.

The Continuing Eruption of Mt

Most of the surface of Mount Etna. Is covered by historic lava flows dating back to eruptions as old as 300,000 years.

The Continuing Eruption of Mt

Scientists believe Mount Etna. Started as a submarine volcano that gradually grew to stand above sea level on layer upon layer of solidified lava.

Among all the world’s volcanoes. Mount Etna has the longest recorded history of eruptions. Dating back to 1500 B.C. Since then, the volcano has erupted about 200 times. And has been very active in recent decades. In particular, 2001 was a busy year for Mount Etna. As there were 16 eruptive episodes by the time a new spate of activity began on July 13, 2001. That eruption was accompanied by earthquakes. And the opening of at least five vents on the volcano that released thick lava flows. And vast columns of steam and smoke. Officials were watching closely as the lava flowed to within 5 km (3 miles) of the town of:. Nicolosi (as of July 21).

Concerning the lunar month of approximately 29.53 days as viewed from Earth. The lunar phase or Moon phase is the shape of the Moon‘s directly sunlit portion. Which can be expressed quantitatively using areas or angles. Or described qualitatively using the terminology of the four major phases (new moon, first quarter:. Full moon, last quarter) and four minor phases (waxing crescent, waxing gibbous, waning gibbous, and waning crescent).

Earthtopomaps – Moon Phases 2020 – Southern Hemisphere – 4K
Earthtopomaps – Moon Phases 2020 – Southern Hemisphere – 4K

The lunar phases gradually change over a synodic month (c. 29.53 days) as the orbital positions of the Moon around Earth, and Earth around the Sun, shift. The visible side of the Moon is variously sunlit, depending on the position of the Moon in its orbit. With the sunlit portion varying from 0% (at new moon) to nearly 100% (at full moon).

Each of the four major lunar phases is approximately 7.4 days±19 hours ( 6.58–8.24 days ) the variation being due to the eccentricity of the Moon’s orbit and thus it orbiting at varying speeds.

NASA-Led Project Tracking Changes to Water, Ecosystems, Land Surface.

NASA-Led Project Tracking Changes to Water, Ecosystems, Land

A drought-stricken Lake Powell, the second largest reservoir in the U.S., is captured here in 2014 by the Landsat 8 satellite. Bleached rock along the edges shows the reservoir’s shoreline when at capacity. NASA’s OPERA project brings together multiple space missions to track such water and land changes.

Merging data from multiple satellites. OPERA can help government agencies. Disaster responders. And the public access data about natural and human impacts to the land.

Where are flood waters flowing after major storms? Where are the changes in tree and plant cover after droughts, wildfires, deforestation, or mining? How much did the land move during an earthquake or volcanic eruption? Scientists routinely rely on data-intensive analysis and visualization of satellite observations to track Earth’s ever-changing surface. A new project will make it possible for anyone with an internet connection to begin to answer these questions. And more about changes to our dynamic planet.

The OPERA (Observational Products for End-Users from Remote Sensing Analysis) project is managed by NASA’s Jet Propulsion Laboratory.

NASA-Led Project Tracking

With partners from NASA’s Goddard Space Flight Center, the U.S. Geological Survey (USGS), the University of Maryland, the University of Alaska Fairbanks, and Southern Methodist University. Scientists conceived OPERA in 2020 to address satellite data needs across different federal agencies. And to enable better access to information on everything from water management to wildfire monitoring. The goal is to make specific satellite-based observations free and timely for users. The first offerings will be available in April 2023, with more to follow.

NASA-Led Project Tracking Changes to Water

As a series of atmospheric river events deluged parts of California this winter. OPERA’s surface water maps recorded the potential overflow of several dams in a region that is home to millions of people.

“Quite often satellite missions are driven by science, applications, or technology demonstration. In OPERA, we focus on fulfilling the operational needs identified by federal agencies who rely on our work.” Said David Bekaert, OPERA project manager based at JPL. “We leverage cloud computing to turn massive amounts of satellite observations into analysis-ready products relevant to our federal stakeholders. Shortening the path from satellite observation to stakeholder decision is a key driver behind the overall implementation and execution of OPERA.”

OPERA is aggregating a unique combination of user-friendly data about Earth’s dynamic surface water and land. Noted John Jones, a USGS scientist and OPERA project partner.

“The magic of OPERA is that it transcends any one space mission,” said Gerald Bawden. Program scientist at NASA Headquarters in Washington. Who helped envision the project as part of the interagency Satellite Needs Working Group. Created by the Office of Management and Budget and the U.S. Group on Earth Observations. The Satellite Needs Working Group seeks to identify the satellite needs of U.S. federal agencies. And develop new remote sensing products that fulfill their observational gaps.

NASA-Led Project Tracking Changes to Water, Ecosystems, Land

The first round of OPERA products ties together visible and infrared measurements from the:. ESA (European Space Agency) Sentinel-2 A/B satellites. And from Landsat 8, built by NASA and operated by the USGS. These instruments will soon be augmented by data from the cloud-penetrating radars on:. ESA’s Sentinel-1 A/B satellites and the recently launched Surface Water. And Ocean Topography (SWOT) satellite, a partnership between NASA and the French space agency CNES (Centre National d’Études Spatiales). OPERA will eventually ingest satellite radar data from the NASA-Indian Space Research Organisation Synthetic Aperture Radar (NISAR) satellite. Planned for launch in 2024.

The OPERA Land Surface Disturbance Alert provisional product showed vegetation loss west of:. Lake Tahoe following California’s largest fire of 2022. The red and purple colors indicate significant loss.

Mapping Surface Water

OPERA’s Dynamic Surface Water eXtent product suite offers what may be the most comprehensive data source for monitoring Lakes. Rivers, Reservoirs And Streams. The first phase relies on Harmonized Landsat Sentinel-2 (HLS) optical data to generate near-global surface water mapping every few days at a 30-meter spatial resolution. Subsequent phases will use Sentinel-1, SWOT, and NISAR radar observations to map surface water more often (because radar can penetrate cloud cover).

For example, when a series of nine atmospheric river events brought heavy rain and snow to California in the winter of 2022-23, several flood-control dams faced risks of overflowing. OPERA’s surface water maps chronicled the dramatic filling of these reservoirs.

Monitoring Surface Disturbance

OPERA’s products offer new insights into both environmental and geological processes taking place on Earth’s land surfaces. Complementing its water product suite, OPERA’s Surface Disturbance product uses HLS data to map changes in vegetation cover. It could be used to observe the scars and regrowth after wildfires, track growing cities, or even discover insect infestations in forests.

“We are very excited to employ integrated Landsat and Sentinel-2 data,” said Matt Hansen, a professor at the University of Maryland and OPERA project partner. “The combined observations provide an unprecedented capability and, we expect, an unprecedented record of global land change.”

NASA-Led Project Tracking Changes to Water, Ecosystems, Land

For example, the Mosquito Fire was detected on Sept. 6, 2022, and burned predominantly in the Tahoe and Eldorado National Forests. OPERA’s surface disturbance data product shows vegetation losses due to the fire – California’s largest of the year – which covered some 76,788 acres and lasted for 50 days.

Measuring North America Surface Displacement

OPERA’s third product, slated for release in late 2024, will provide a history of how much land surfaces in North America have moved, or deformed, due to geologic and human activities. The surface displacement product will map surface motion that is otherwise imperceptible without a vast network of GPS instruments.

“This is a transformative product for detecting landslides, sinkholes, earthquakes, volcanoes – anything that is changing the land surface,” said Bawden. “Using these satellites, we’re able to measure motions on the ground surface less than an inch. And we can begin to explore how those motions are impacting everything living there.”

NASA-Led Project Tracking Changes to Water, Ecosystems, Land

All OPERA products are publicly accessible. The surface water and surface disturbance products are currently available through NASA Distributed Active Archive Centers, Physical Oceanography Distributed Active Archive Center and Land Processes Distributed Active Archive Center, respectively.

Earthtopomaps – Patagonian Plankton Swirls, Phytoplankton

Earthtopomaps – Patagonian Plankton Swirls, Phytoplankton

What are Phytoplankton?

Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.

Earthtopomaps – Patagonian Plankton Swirls, Phytoplankton

Some phytoplankton are bacteria, some are protists, and most are single-celled plants. Among the common kinds are cyanobacteria, silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.

Earthtopomaps - Patagonian Plankton Swirls

Phytoplankton are extremely diverse, varying from photosynthesizing bacteria (cyanobacteria), to plant-like diatoms, to armor-plated coccolithophores (drawings not to scale). (Collage adapted from drawings and micrographs by Sally Bensusen, NASA EOS Project Science Office.)

Earthtopomaps – Patagonian Plankton Swirls, Phytoplankton

Like land plants, phytoplankton have chlorophyll to capture sunlight, and they use photosynthesis to turn it into chemical energy. They consume carbon dioxide, and release oxygen. All phytoplankton photosynthesize, but some get additional energy by consuming other organisms.

Earthtopomaps - Patagonian Plankton Swirls Phytoplankton create rich blooms of color in the Atlantic Ocean near South America

Phytoplankton growth depends on the availability of carbon dioxide, sunlight, and nutrients. Phytoplankton, like land plants, require nutrients such as nitrate, phosphate, silicate, and calcium at various levels depending on the species. Some phytoplankton can fix nitrogen and can grow in areas where nitrate concentrations are low. They also require trace amounts of iron which limits phytoplankton growth in large areas of the ocean because iron concentrations are very low. Other factors influence phytoplankton growth rates, including water temperature and salinity, water depth, wind, and what kinds of predators are grazing on them.

A giant planet where it rains glass HD 189733 b – Earthtopomaps

DISCOVERED 2005

PLANET TYPE: Gas Giant

This far-off blue planet may look like a friendly haven – but don’t be deceived!. Weather here is deadly. The planet’s cobalt blue color comes from a hazy, blow-torched atmosphere containing clouds laced with glass. Howling winds send the storming glass sideways at 5,400 mph (2km/s), whipping all in a sickening spiral. It’s death by a million cuts on this slasher planet!

HD 189733 b is a gas giant exoplanet that orbits a K-type star. Its mass is 1.13 Jupiters, it takes 2.2 days to complete one orbit of its star, and is 0.0313 AU from its star. Its discovery was announced in 2005.

Huble’s Space Telescope Imaging Spectrograph measured changes in the color of light from the planet before, during and after a pass behind its star. There was a small drop in light and a slight change in the color of the light. “We saw the light becoming less bright in the blue but not in the green or red. Light was missing in the blue but not in the red when it was hidden,” said research team member Frederic Pont of the University of Exeter in South West England.” This means that the object that disappeared was blue.”

Earlier observations have reported evidence for scattering of blue light on the planet. Hubble observations confirmsed the evidence.

A giant planet

If seen directly, this planet would look like a deep blue dot, reminiscent of Earth’s color as seen from space. That is where the comparison ends.

On this turbulent alien world, the daytime temperature is nearly 2,000 degrees Fahrenheit, and it possibly rains glass — sideways in howling, 4,500-mph winds. The cobalt blue color comes not from the reflection of a tropical ocean as it does on Earth, but rather a hazy, blow-torched atmosphere containing high clouds laced with silicate particles. Silicates condensing in the heat could form very small drops of glass that scatter blue light more than red light.

Hubble and other observatories have made intensive studies of HD 189733 b and found its atmosphere to be changeable.

Detection Method: Radial Velocity

The radial velocity method measures slight changes in a star’s velocity as the star and the planet move about their common center of mass. Astronomers can detect these variances by analyzing the spectrum of starlight. In an effect known as Doppler shift, light waves from a star moving toward us are shifted toward the blue end of the spectrum.

If the star is moving away, the light waves shift toward the red end of the spectrum.

This happens because the waves become compressed when the star is approaching the observer and spread out when the star is receding. The effect is similar to the change in pitch we hear in a train’s whistle as it approaches and passes.

The radial velocity method measures slight changes in a star’s velocity as the star and the planet move about their common center of mass. Astronomers can detect these variances by analyzing the spectrum of starlight. In an effect known as Doppler shift, light waves from a star moving toward us are shifted toward the blue end of the spectrum. If the star is moving away, the light waves shift toward the red end of the spectrum. This happens because the waves become compressed when the star is approaching the observer and spread out when the star is receding. The effect is similar to the change in pitch we hear in a train’s whistle as it approaches and passes.

Earthtopomaps Popocatépetl Volcano Keeps on Puffing – Earth

Earthtopomaps Popocatépetl Volcano Keeps on Puffing.

Popocatépetl is one of Mexico’s most active volcanoes. During the mountain’s current period of eruption, ongoing since 2005, volcanic emissions frequently billow from its summit crater.

In spring 2023, striking plumes were captured in images acquired by satellites and astronauts, both orbiting hundreds of kilometers above Earth’s surface.

The Operational Land Imager (OLI) on Landsat 8 acquired this image (above) on April 14, 2023.

Monitoring systems on that day detected water vapor, volcanic gases, and ash, according to Mexico’s National Center for Disaster Prevention. (CENAPRED).

The volcano still puffed on May 2, 2023. When an astronaut on the International Space Station took this photograph (below). It shows a wider view of the region that includes Iztaccihuatl a dormant volcanic mountain. And the nearby town of Puebla. Mexico City (not pictured) is about 70 kilometers (40 miles) northwest of Popocatépetl.

The source of the other plume, located between the two volcanoes, is unclear based on this photograph. 

Past research has suggested that satellite-detected hotspots on the volcano’s slopes could be due to fire. Also notice the green vegetated areas surrounding the peaks. Conifer forests and high-mountain prairies are an important part of the area’s ecosystem.

Around the time of these images, volcanic plumes rose as high as 7.3 kilometers (24,000 feet), according to the Washington Volcanic Ash Advisory Center.

As of May 4, the volcanic alert level remained yellow (the middle level of a three-color scale).

NASA Earth Observatory image by Lauren Dauphin, using Landsat data from the U.S. Geological Survey. Astronaut photograph ISS069-E-8304 was acquired on May 2, 2023, with a Nikon D5 digital camera using an 400 millimeter lens and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 69 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed.

The International Space Station Program supports the laboratory as part of the ISS National Lab  to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Kathryn Hansen.

These changes are in part because of climate change amplifying environmental disturbances.
Google Earth a more detailed understanding of earth’s land than ever before.
( Google Earth Pro ): So current datasets might classify a satellite image of a city as ‘built-up,’. But visit any city and you’ll see our world is far more dynamic. While you might see lots of buildings. You’ll also see trees or even snow on the ground from a recent storm.
Manage and restore land and monitor the effectiveness of those plans using alert systems to notify when unforeseen land changes are taking place.
Not only is our world more dynamic than individual land types it’s also constantly changing.
This means that not only is the land cover information in Dynamic World more detailed. Week or month than existing datasets. This level of detail allows scientists and policymakers to detect and quantify the extent of recent events anywhere on the globe such as snowstorms, wildfires or volcanic eruptions within days.

For example a map that analyzes crop harvests between particular dates.

Dynamic World is also useful for understanding longer-term trends of seasonal ecosystem change. As seen in the Okavango Delta. An area that attracts thirsty wildlife when it floods in July and August and then dries from September to October.
Whether it’s forests in the Amazon, agriculture in Asia, urban development in Europe or seasonal water resources in North America. With this information, people like scientists and policymakers can monitor and understand land and ecosystems so they can make more accurate predictions and effective plans to protect our planet in the future.

PLANET TYPE: Super Earth

55 Cancri e , also known as Janssen , orbits a star called Copernicus only 41 light years away.

The molten surface is completely uninhabitable, but above the burning horizon, Janssen’s sister planet, Galileo, hangs in a dark sky. Silicates in the atmosphere would condense into clouds on the tidally-locked planet’s darkside reflecting the lava below. So, the skies would sparkle.

Detection Method: Transit

If a planet passes directly between a star and an observer’s line of sight. It blocks out a tiny portion of the star’s light. Thus reducing its apparent brightness. Sensitive instruments can detect this periodic dip in brightness. From the period and depth of the transits. The orbit and size of the planetary companions can be calculated. Smaller planets will produce a smaller effect, and vice-versa. A terrestrial planet in an Earth-like orbit, for example, would produce a minute dip in stellar brightness that would last just a few hours.

In 2019 the presence of water vapour in K2-18b’s atmosphere was discovered, drawing attention to this system. Its atmosphere may have an unexpectedly small concentration of methane, although observation uncertainties preclude a definitive determination. K2-18b has been studied as a potential habitable word that, temperature aside, resembles more a gas planet like Uranus or Neptune than Earth.
