Why is Methane Seeping on Mars? NASA Scientists Have New Ideas

The most surprising revelation from NASA’s Curiosity Mars Rover — that methane is seeping from the surface of Gale Crater — has scientists scratching their heads. Living creatures produce most of the methane on Earth. But scientists haven’t found convincing signs of current or ancient life on Mars, and thus didn’t expect to find methane […]

Hubble Goes Hunting for Small Main Belt Asteroids

Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don’t stop to be photographed as they zip along their orbits around the Sun. Astronomers recently used a trove of archived images taken by NASA’s Hubble […]

NASA’s Ingenuity Mars Helicopter Team Says Goodbye … for Now

The final downlink shift by the Ingenuity team was a time to reflect on a highly successful mission — and to prepare the first aircraft on another world for its new role. Engineers working on NASA’s Ingenuity Mars Helicopter assembled for one last time in a control room at the agency’s Jet Propulsion Laboratory in […]

NASA’s LRO Observes 2024 Solar Eclipse Shadow

Editor’s Note, April 16, 2024: This story has been updated to remove an unclear secondary image and caption. As the Moon blotted out the Sun to viewers across the United States during the April 8 solar eclipse, NASA’s Lunar Reconnaissance Orbiter (LRO) captured an image from some 223,000 miles away of the highly anticipated celestial […]

NASA’s LRO Finds Photo Op as It Zips Past SKorea’s Danuri Moon Orbiter

NASA’s LRO (Lunar Reconnaissance Orbiter), which has been circling and studying the Moon for 15 years, captured several images of Korea Aerospace Research Institute’s Danuri lunar orbiter last month. The two spacecraft, traveling in nearly parallel orbits, zipped past each other in opposite directions between March 5 and 6, 2024.

How NASA’s Roman Telescope Will Measure Ages of Stars

Guessing your age might be a popular carnival game, but for astronomers it’s a real challenge to determine the ages of stars. Once a star like our Sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for billions of years. One exception to that rule is the […]
