Solar System Mimics Ours; The Big Empty; Closest Human Relative?

May 3, 2017

Nearby Planetary System Mimics our Solar System A group of scientists using NASA’s airborne Stratospheric Observatory for Infrared Astronomy or SOFIA recently completed a study that confirmed their previous findings of a young and nearby planetary system. The researchers found that the system surrounding the star Epsilon Eridani, which is about 10.5 light years away […]

Cosmic Impact May Have Caused Prehistoric ‘Big Freeze’

September 3, 2013

Scientists say they may have found a link between a dramatic climate shift nearly 13,000 years ago and an asteroid or comet that struck the Canadian province of Quebec. Researchers at Dartmouth College say the comet/asteroid strike took place at the beginning of a global cooling event known as the Younger Dryas stadial or the […]
