Ancient Flood Channels Cut Deep into Mars

Relatively recently, water blasted out from an underground aquifer on Mars, carving out deep flood channels in the surface that were later buried by lava flows, radar images complied from an orbiting NASA probe shows.

In a nutshell, the Mars Reconnaissance Orbiter has used radar to look inside Mars’ crust, under a layer of ancient lava, exposing a valley that was formed by a huge surge of water! If that’s not crazycool, I don’t know what is.
