Ancient explosion of ocean life wasn’t triggered by space rock bombardment: study

Explosion of ocean life nearly 471 million years ago, known as the Great Ordovician Biodiversification Event (GOBE), wasn’t triggered by a meteorite bombardment of Earth, an international team of researchers found in a new study.

Challenging the widely-accepted theory, the new study by researchers from Sweden and Denmark suggested that the ancient ocean creature expansion started roughly 2 million years before the space rock bombardment.

Debris created by prehistoric space collision still falling on Earth

A Connecticut-sized space rock’s collision with another object millions of years ago sent shrapnel raining down on Earth; and even today, they make up the biggest group of meteorites that land on our planet.

That 466-miillion-year-old collision, which is considered to be the biggest cataclysm to occur in our celestial neighborhood in nearly 3 billion years, broke the large space rocks into millions of pieces. Those pieces continued to slam into one another, creating more debris.

U.S. Air Force’s missile-detection satellite successfully put in orbit

The United Launch Alliance (ULA) Atlas V rocket successfully put the U.S. Air Force’s Space-Based Infrared System Geosynchronous Earth Orbit Satellite (SBIRS Geo-3) in high orbit, on its way to a surveillance post more than 22,000 miles above Earth’s surface.

The Atlas V rocket took off from Florida’s Cape Canaveral Air Force Station at 7:42 p.m. ET on Friday, and dropped off the missile detection and early warning satellite in orbit 44 minutes later.
