Part of Mars broke off and fell on Earth. It has revealed a big secret

India Today  

Eleven million years ago, an asteroid slammed into Mars, scattering fragments of the red planet into space. In a groundbreaking discovery, scientists have determined that liquid water was present on Mars 742 million years ago, thanks to the meteorite found at Purdue University. The team's analysis revealed that these minerals formed 742 million years ago, a time when liquid water …
