Read our privacy policy 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. “These elements were added as the zircon formed 4.45 billion years ago, suggesting water was present during early Martian magmatic activity,” Cavosie explained. It formed billions of years ago Cavosie said the research showed that even though Mars’ crust was hit by massive meteorites that caused a major upheaval of the planet’s surface, water was present during the early Pre-Noachian period, prior to about 4.1 billion years ago.
