Mars Was Once Covered by a Vast Ocean—Here’s the Evidence

Mars, the red planet we know today as cold, dry, and desolate, might not have always been this way. New research from the University of Arkansas suggests that, billions of years ago, Mars was home to massive rivers that flowed into a vast ocean in its northern hemisphere. This discovery, shared in a recent study published in Geophysical Research Letters, builds on earlier speculation about the presence of water on Mars, with evidence of rivers a…

Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of Arkansas found strong evidence in Mars’ geology of an ocean in the planet’s northern hemisphere. “We don’t know of any lifeforms on Earth, or anywhere in the universe, that don’t require liquid water. So the more liquid water we have on Mars, a simple argument could be made…
