Flood inundation models are tools that predict where water flows, how deep it gets, how fast it moves and how long it remains during a flood event. But despite recent advances in flood inundation models, some flood modeling paradigms are being used beyond their range of applicability rather than leveraging the strengths of different methods. A new article in Review of Geophysics explores the...

Seen during Artemis II's lunar flyby on April 6, 2026, the Moon and Earth align in the same frame, each partially illuminated by the Sun. The Moon's surface appears in sharp detail in the foreground, while Earth sits much farther away, smaller and softly lit in the background. A faint reflection in the spacecraft window is also visible, subtly overlaying the scene. Though their phases differ, both are shaped by the same sunlight, revealing the geometry of the Sun-Earth-Moon system from deep space.

NASA's Artemis II mission will conclude its 10-day journey around the Moon on April 10, 2026, when the crew splashes down off the California coast. While additional imagery will continue to be processed after their return, the astronauts have already delivered a remarkable collection of photos. Among them is a shot of Earthset, echoing the iconic Earthrise photos taken by Apollo 8 astronauts in 1968.

When it comes to wildfires, the story may seem straightforward: As forests burn, they release greenhouse gases like carbon dioxide, carbon monoxide, and methane that warm the planet. But in the far northern parts of North America, wildfires don't always follow the same script. In a new study published in Nature Geoscience, researchers found that forest fires in Alaska tend to have a warming...

On the eastern, arid side of the Andes, the plains of southern Argentina stretch from the mountains to the Atlantic coast. The landscape often appears dry and brown, interrupted by colorful glacier-fed lakes, but a storm in early April 2026 blanketed swaths of the land in white. The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA's Terra satellite captured this image of the snowy Patagonian Desert on the morning of April 3.

Researchers have found evidence of a sandstorm on Mars that occurred about 3.6 billion years ago, marking the first time a sandstorm has been recognized in the Martian stratigraphic record. They published their findings in Geology. It's not that scientists didn't know that wind once blew on Mars. It does so now, and features on the planet's surface, like dry riverbeds...

Take a tour through volcanic history on the edge of the Sierra Nevada near Mammoth Lakes, California. Between the tall granite peaks to the west and the Basin and Range province to the east, overlapping volcanic complexes imprint the landscape with a collection of craters, cones, and calderas. The area, still restless today, draws interest from geologists studying Earth's processes and from planetary scientists exploring its commonalities with volcanic terrain elsewhere in our solar system.

Last Friday, President Trump released the fiscal year 2027 President's Budget Request. What we are seeing is devastating, and it demands a forceful response. As our policy team details on The Bridge, this budget is largely a repeat of last year's proposal, but repetition does not soften the blow. NASA's Science Mission Directorate is cut by nearly half its budget.
