Mars

Was alien life in "hot water" on Mars billions of years ago? New evidence from the Martian meteorite "Black Beauty" suggests so.

Curiosity has just finished the latest leg of its 12-year Mars mission and will now set out to explore miles of web-like surface features left behind by ancient water on the Red Planet. The zig-zagging rocks could also provide clues about whether Mars once harbored extraterrestrial life.

Data from China's Zhurong rover has revealed what appears to be an ancient shoreline streaking through Mars' northern hemisphere.

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving life a longer window to take hold on the Red Planet.

NASA's Perseverance Mars rover was treated to a 'googly eye' solar eclipse on Sept. 30 as the planet's moon Phobos passed in front of the sun.

NASA's Perseverance rover found strange green spots in Martian rock, potentially indicating a past interaction with liquid water.

On Sept. 30, NASA's Perseverance rover turned its eyes toward the sky and photographed a solar eclipse from Mars, capturing the tiny moon Phobos crossing the sun's face.

A new NASA-led study suggests that photosynthetic microbes could thrive in hidden bubbles of meltwater below patches of ice on Mars. This could be one of the easiest places to search for extraterrestrial life "anywhere in the universe," the team says.

"Some of these features are surprisingly dark compared with their icy surroundings, earning their nickname of 'cryptic terrain.'"
