Roamed Earth When It Was on the Other Side of the Milky Way

When dinosaurs ruled the Earth, the planet was on a completely different side of the Milky Way galaxy. This was revealed by NASA a few years back through an animation.

The Animation by NASA

In November 2019, an animation by NASA scientist Dr Jessie Christiansen showed just how long the dinosaurs’ reign lasted, and how short the era of humans has been in comparison, by tracing the solar system’s movement through the galaxy.

Sun Orbits the Centre of the Milky Way

The sun orbits the Milky Way’s centre, completing its rotation every 250 million years or so. And, the animation by Dr Christiansen showed that last time the solar system was at its current point in the galaxy, the Triassic period was in full swing and dinosaurs were just beginning to emerge.

How did this Animation Come Up?

Christiansen got the idea to develop this animation when she was leading a stargazing party at California Institute of Technology in Pasadena.
