Researchers have uncovered what may be the oldest direct evidence of hot water activity on Mars, suggesting the red planet could have supported life billions of years ago.
Scientists at Australia’s Curtin University made the discovery while studying a famous Martian meteorite — nicknamed “Black Beauty” — that was found in the Sahara Desert in 2011. The rock, which was created by rapidly cooled lava, contains 10 times more water than other Martian meteorites and formed more than 2 billion years ago.
