The Mars we know today is dry, dusty, and (probably) devoid of life, but that wasn’t always the case. Scientists believe Mars was once a wet world, with vast oceans that may have or may not have supported life. Now, a new study suggests that if there was any life hanging out on the Red Planet three billion years ago, it had to deal with a massive asteroid impact and the tsunami that followed.
The study, which was published in the American Geophysical Union’s Journal of Geophysical Research, focuses on a colossal 75-mile-wide impact site known as the Lomonosov crater. The gigantic scar on the planet’s surface is what remains of the incredibly destructive event, but there’s still plenty it can teach us.
