Mars

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.

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.

On March 11, NASA's Perseverance Mars rover spotted a mysterious rock made of hundreds of tiny spheres that resemble spider eggs. Studying its formation could help us look for fossilized remains of microbial life on Mars.

China's Zhurong rover has found evidence of an ancient shoreline buried deep beneath the planet. That could point to an ocean, a beach, and to life.

New research has revealed that Martian dust's red hue comes from reactions that occurred in wet — not dry — conditions, and it could have implications for the possibility of life on the planet.
