Mars

NASA's Perseverance rover is exploring a new Mars region called Krokodillen, which is thought to harbor some of the oldest and most intriguing rocks on the Red Planet.

NASA's Perseverance rover recently captured a photo of green auroras shining in the Martian sky for the first time. The alien light show, previously assumed to be impossible, could be visible to future astronauts.

By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid water to flood the planet with an ocean thousands of feet deep.

Wave-like soil patterns on the Martian surface match those found in Earth's cold, mountain regions, which could help scientists better understand the Red Planet's climate history and search for signs of life.

NASA's Perseverance rover on Mars has discovered unusual "float" rocks on the rim of Jezero Crater while searching for signs of ancient microbial life. Scientists are investigating their origin.

Researchers bombarded lichens with a year's worth of Martian radiation in just 5 hours — and they survived, hinting that the extremophiles could potentially live on the Red Planet.

NASA's Curiosity Rover has discovered long carbon chains on Mars. On Earth, molecules like these are overwhelmingly produced by biological processes.

Samples drilled by the Curiosity rover on Mars have revealed abundant signs of a carbon cycle that remained hidden from orbital scans, alongside clues of how life may have been wiped out on the planet.

Video footage captured by NASA's Perseverance rover shows a small "dust devil" merging with a much larger twister on the surface of Mars.
