Scientists Astonished by Glimpse of Huge, Ancient Ocean on Mars

Scientists have long suspected that Mars was once teeming with water, a tropical oasis with vast river systems that may have been able to support life billions of years ago.
To get a better picture of what such a lush ocean world could’ve looked like, an international team of researchers used satellite data to simulate the sea level in a colossal geographic feature called Coprates Chasma, which is part of the Valles Marineris, the largest canyon in the entire solar system.
While examining the satellite imagery, the team concl
