Batagaika Crater Expands

The walls of this immense crater look as though they could have been scooped out of ice cream, but for the protruding ends of plant roots. And at more than 85 meters (275 feet) tall in places, Batagaika’s cliff-faces keep growing while the crater below becomes deeper and wider.

Batagaika Crater has formed as rising temperatures have thawed the permafrost in Siberia....

Tsunami Study Challenges Long-held Formation Theory

A new NASA study is challenging a long-held theory on how tsunamis form and offering a new method for forecasting the powerful waves. Most tsunamis result from a massive shifting of the seafloor -- usually from the subduction, or sliding, of one tectonic plate under another during an earthquake. Using a large wave tank, researchers...

On the rust-colored north flank of one of Earth’s largest volcanoes, a backpack-sized instrument monitors our atmosphere and, at the same time, helps set the stage for possible human exploration of other worlds.

Designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the instrument tracks levels of methane and carbon dioxide, two gases crucial for studying the...

Satellites Eye Winter Cover Crops

For the second year in a row, farmers in Maryland planted a record amount of winter cover crops in 2016-17. These cold-tolerant crops—including wheat, rye, barley, and radish—are planted in the fall. In addition to increasing soil health and boosting yields, cover crops reduce soil erosion and absorb nutrients such as nitrogen that could otherwise affect...

A Rare Clear Day on Mount Washington

Summer and fall generally bring the clearest skies of the year to the Presidential Range, the highest peaks in New England. Clouds were certainly scarce on October 3, 2014, when the Operational Land Imager (OLI) on Landsat 8 collected the data that was used in this three-dimensional image.

For much of the rest of the year, weather tends to be foul at the...

Another View of Petermann Glacier’s New Crack

In early April, remote sensing scientist Stef Lhermitte examined Sentinel-2 satellite images and saw a new crack developing on Greenland’s Petermann Glacier. About two weeks later, Landsat 8 also got a look.

But the space-based view is not the only evidence of a new crack in the large glacier. NASA’s Operation IceBridge has been making science...

South Australia, Wet and Dry

An astronaut aboard the International Space Station captured these photographs of agricultural patterns in the Riverland region of South Australia. The use of a powerful lens makes it possible to see individual buildings in the small towns, a bridge joining the towns, and one of the many locks on the river.

Renmark is one of the major towns in a line of...

Winter at Karazhanbas Oil Field

Kazakhstan has roughly 3 percent of the world’s crude oil reserves. With proven reserves of 30 billion barrels, the large, land-locked country has the second most in Eurasia and the twelfth most in the world, just behind the United States.

The oil is spread between 172 oil fields, mainly in the western part of the country. The Operational Land Imager (OLI) on...

NASA's fleet of Earth science satellites, along with Earth science instruments on the International Space Station, surveys the whole globe, even the most remote parts that are difficult if not impossible to visit. With instruments in space, scientists can get data for the whole globe in detail that they can't get anywhere else. This visualization shows the NASA fleet in 2017, from low Earth...

Sierra Snowpack Bigger Than Last Four Years Combined

New NASA data show that snowpack in Tuolumne River Basin—a major source of water for San Francisco and California’s Central Valley—is currently greater than that of the four previous years combined. NASA’s Airborne Snow Observatory (ASO) measured snowpack in the Tuolumne Basin of the Sierra Nevada at 1.5 cubic kilometers (1.2 million...

Lava Glows Atop Nishinoshima

Once again, Nishinoshima Island promises to gain ground. Roughly 1,000 kilometers (more than 600 miles) south of Tokyo, the island has been growing steadily since 2013, when the volcano broke the water line.

This image of fresh lava was created on April 19, 2017 by combining data from the Thermal Infrared Sensor (TIRS) and Operational Land Imager (OLI) on the...

From the Ground Up: Building an Earth Science Satellite (HyspIRI Hawaii, Part 4)

Noxious sulfur dioxide gas and other pollutants emitted from Kilauea Volcano on the Island of Hawai`i react with oxygen and atmospheric moisture to produce volcanic smog (vog) and acid rain. These forms of pollution are recurrent health issues for the citizens of Hawaii. Vog can aggravate preexisting respiratory...

An Optimistic View For Earth Day

As we arrive at Earth Day 2017, reporting on Earth science can sometimes feel like a gloomy affair. Global temperatures are at record highs. Arctic sea ice is in pretty bad shape. Bleaching events are taking a toll on coral reefs. And as an interesting article in EOS recently noted, humanity is affecting the very shape of Earth’s surface in unprecedented...

California Reservoirs Rise from Drought to Deluge

A five-year drought in California ended spectacularly this winter, with the state emerging from one of its driest periods on record by enduring one of its wettest. Reservoirs, lakes, and mountainsides are now brimming with water and snow, though scientists caution that the unseen reservoirs—underground aquifers—are a long way from having the...

Mystery Solved: Dust—Not Volcanic Ash—on Larsen C Ice Shelf

On April 4, 2017, archaeologist Mark Walters tweeted an intriguing set of satellite images of a dark smear on the Larsen C Ice Shelf. Was it volcanic ash from a recently active volcanic vent, he wondered?

The tweet — and especially a bright, red spot in an infrared image (lower right in the first image) — generated interest among...
