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.

A new study has identified an exoplanet that is just 3 million years old — around 1,500 times younger than Earth — alongside a misaligned protoplanetary disk that researchers cannot explain.

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

Astronomers using the James Webb Space Telescope have detected possible signs of gases released by volcanic activity on a distant exoplanet.

Voyager 2's 1986 flyby of Uranus, the main source of our knowledge of the icy planet, could have come at the same time as a weird plasma burst from the sun.

Pluto was demoted from a planet to a dwarf planet in 2006. So why is its status still so controversial today?

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.

Surface features of Uranus' icy moon Miranda point to the existence of a once deep ocean, one that still may exist today.
