Two scientists. One unforgettable view of our planet. What's it like to see the Artemis II Earthrise image through the eyes of a lunar scientist? How about an oceanographer? Jacob Richardson & Ivona Cetinic are here to tell us. Explore Artemis II data: go.nasa.gov/Artemis2LunarSci…

Antarctica’s Thwaites Glacier could contribute more to sea level rise by the end of the century than some previous estimates. @NASAJPL helped develop a model that better accounts for seawater moving beneath the ice, improving simulations of the glacier’s retreat.

An island on the move! In July 2026, a forested island the size of 2 football fields appeared in Canada’s Williston Reservoir and then vanished. 🏝️ See how scientists used Landsat and Sentinel satellite data to track its 19-mile journey! 🛰️

This summer, @NASA scientists spent six weeks chasing fire clouds. 🔥☁️ Using planes and trucks, the team studied several dangerous, smoke-infused clouds generated by wildfires. The data will help predict where these clouds may form and improve climate and atmospheric models.

Above the smoke layer are puffy white clouds, including a puff of very tall clouds. Credit: INSPYRE / Bernadett Weinzierl

Albedo keeps us cool — literally! Parts of Earth with high albedo, like sea ice or clouds, reflect sunlight, which helps regulate Earth’s temperature.
NASA Goddard
@NASAGoddardOct 5
Let's reflect... Albedo is a measure of how much light and heat a surface reflects. Lighter objects tend to have higher albedo, and darker objects have lower. This reflectivity plays an important role in studying the makeup of the surface of bodies like the Moon.

NASA can see penguin poop from space. Also, it’s pink. 💩 The exact shade can tell scientists a lot about Adélie penguins and their Antarctic environment. The results come from a study of over 100 penguin sites and about 30 years’ worth of @nasa @usgs Landsat satellite images.

2026 has been a busy season for tropical cyclones in the northeastern and central Pacific basins. This image from NASA’s EPIC camera on the DSCOVR satellite shows four named storms churning on Sept. 27: Nolo, Odalys, Polo, and Rachel.

The Intertropical Convergence Zone appears as a band of puffy white clouds near the equator. The storms are all near this area. Credit: NASA

Arctic sea ice grows and melts with the seasons, reaching an annual minimum extent at the end of summer in the northern hemisphere. On Sept. 12, Arctic sea ice reached its annual minimum extent, tying for the 10th lowest in the satellite record. go.nasa.gov/4AwNBcg

The brown bears in @KatmaiNPS are some of the chonkiest on Earth but, even so, @NASA satellites still can’t see them from space. But we can see their home! Satellite images can help determine how healthy the bears’ environment is, which provides clues to how big they may get. 🐻
Satellite image of Katmai National Park and Preserve in Alaska on September 23, 2014. The landscape is mostly green and brown. The area is mountainous and there is a long mountain range along the right side of the image that is capped with white snow. One of these is Mount Katmai. The jagged shoreline and blue ocean water can be seen in the lower right corner. Credit: NASA
