Mars

NASA shares an iconic image of carbon dioxide ice erupting in geysers when Martian winter turns to spring.

Mars' southern hemisphere absorbs a lot of the sun's energy during the Red Planet's spring, and that may be causing Mars' dust storms, a new study suggests.

Data collected by NASA's InSight lander suggest that ancient internal processes are responsible for the "Martian dichotomy" that splits the Red Planet into two distinct halves.

Tonight (Jan. 13), bright Mars will disappear behind the full Wolf Moon for several hours before reappearing on the other side. It's the only lunar occultation of Mars visible from the U.S. this year. Here's how to get the most out of it.

A NASA satellite has spotted frozen "kidney beans" on Mars' sand dunes trapped in place until springtime. Photographing them can help us determine if there was ever enough water on Mars to sustain life.

As Mars approaches opposition this week, it will become a dazzling spectacle in the night sky. See it at its best now, or wait until 2027.

NASA will explore two different strategies for fetching Mars rocks collected by the Perseverance rover, and there's a chance these samples contain evidence of alien life.

From arachnid-like formations and mysterious blobs to an underground ocean and a giant volcano, here are our 10 favorite things scientists discovered on Mars this year.

Researchers believe dark rocks at the site of a future Mars rover landing mission may be left over from ancient volcanic eruptions, and may be protecting signs of life — if there ever was life on Mars.
