“Water Proof”

A research team from the University of Colorado at Boulder has discovered the ridged shoreline of a dry lake on Mars. Proof that the red planet once had water implies that it may have been able to sustain life at one time. Since the planet is dry today, scientists looking for lake evidence from the past are now excitedly hoping to find paddle boats.

Researchers say the lake formed 3.4 billion years ago. Evidence suggests that, Mars is not so different from Earth. For instance, once the lake dried up, all that beach-front real estate became worthless.
