Despite the team's success in dating the water-rock interaction, the researchers don't think Mars was teeming with water at ...

The Lafayette meteorite was discovered in a drawer at Purdue University in 1931, with no clear indication of how it got there. A new analysis of the rock reveals evidence of liquid water on Mars ...

There, geological evidence of eight impact events, which occurred between 3.6 billion and 3.2 billion years ago, can be found in the rocks and traced through tiny meteorite impact particles called ...

In the layers, researchers can see spherules — tiny, glass-like orbs that form when a meteorite impact melts silica-containing rock. They also see conglomerates, or rocks made of other chunks of ...
