NASA Scientist Shows Dinosaurs Roamed Earth on The Other Side of The Milky Way

Posted by in category: space

When dinosaurs ruled the Earth, the planet was on a completely different side of the galaxy.

A new animation by NASA scientist Jessie Christiansen shows just how long the dinosaurs’ reign lasted, and how short the era of humans has been in comparison, by tracing our solar system’s movement through the Milky Way.

Our Sun orbits the galaxy’s centre, completing its rotation every 250 million years or so. So Christiansen’s animation shows that last time our Solar System was at its current point in the galaxy, the Triassic Period was in full swing and dinosaurs were just beginning to emerge.
