Evidences proving the existence of an ancient ocean on early Mars are growing.
New results show that the giant meteor responsible for the 75-mile Lomonosov crater may have also produced a “mega-tsunami” that scarred ‘for life’ the Red Planet.
According to the new paper, the Lomonosov crater’s rim is the same height as the estimated depth of the ocean and resembles marine craters on Earth.
Moreover, a hole in the southern lip of the crater could have been the result of the ocean roaring back from that direction. Yes, a mega-tsunami!
Previous studies had presented evidences that the ocean’s shores had been shaped by at least one impact in the same general area as the Lomonosov crater. Now this more precise study has narrowed the hypothesis down to a specific impact site. Incredible, no?
Again and again, science is inexact and changes everyday – that’s actually what’s making it so fascinating and exciting to me – and scientists still say there’s no definitive proof that Mars had an ancient ocean billions of years ago.
But still, if I were them, I would closely look for traces of early life near the impact that created this mega tsunami in the Lomonosov crater. What about you?
