Scientists think that our close neighbor – Mars – once experienced one experienced a collision with an asteroid, just like Earth. It happened around 3.4 billion years ago and might have caused a mega-tsunami on the Red Planet. Before the latest studies, the exact location of the impact crater wasn't verified – it was just a theory. To confirm it, a team of astronomers simulated a comet and asteroid collision in the area where they supposed the impact crater was. Could there have been life on Mars before the collision?
