WASHINGTON D.C. — The Perseverance Rover on Mars may have stumbled upon the oldest rocks humans have ever seen and, possibly, evidence of a new setting that ancient Martian organisms could have inhabited, if they ever existed. “This is really one of the most exciting things that this mission is going to do, is to

The time frame in which Neandertals and Homo sapiens heavily intermingled just got a little clearer.

The findings narrow the time frame in which this

Twenty years ago, the seafloor west of Indonesia abruptly pushed upward as a deep undersea fault, where two of Earth’s tectonic plates meet, slipped. The upward shove violently shifted the seawater above, transferring deadly energy from ground to water, and sending the water speeding toward land. The series of tsunamis generated by that magnitude 9.2
