Solar System once had ‘evil twin’ sun which may have wiped out dinosaurs

Recommended Posts


The Solar System once had two suns, scientists believe, and one of them may have wiped out the dinosaur

A theoretical physicist at the University of California and an astronomer from Harvard University have discovered that most stars are born with a ‘brother’ and our own Sun is likely to be no exception.

In fact, this ‘evil twin’ which has been dubbed Nemesis, may have been responsible for kicking an asteroid into Earth’s orbit which led to the extinction of the dinosaurs.
