At a time when dinosaurs lived on Earth, our planet was in a completely different part of our galaxy, says NASA astrophysicist Dr. Jessie Christiansen.

An animation prepared by Christiansen shows how long dinosaurs had lived on Earth, and how short, comparing to the dinosaur era, is the existence of man. All this illustrates the movement of our planetary system around the galaxy.

 

The sun moves around the center of the Milkyway galaxy, and it takes about 250 million years to fully rotate around this center. At present, the Earth and the Sun, having made a tour along the galaxy, have returned to the same part where they were in the era of the Triassic period. It was in Triassic when dinosaurs only began to appear on Earth. That time, when the most famous dinosaurs appeared on our planet (stegosaurs, velociraptors, tyrannosaurs, etc.), our planet was in another part of the galaxy.

The animation depicted by Christiansen shows the movement of our planetary system around the center of the galaxy with points superimposed on the trajectory of movement, where certain types of dinosaurs appear.

Our entire galaxy is also moving and slowly approaching the Andromeda galaxy.

“The animation shows that we are back to the same point, but in reality, the whole galaxy has come a very long way,” emphasizes Dr. Christiansen. “Our solar system doesn’t travel to the center of the galaxy and then back again. We always stay about this distance away,” she added.

Therefore, our planetary system, after complete rotation around the center of the galaxy, is at a slightly different point than it was 250 million years ago.

Dr. Christiansen also indicates that our planetary system has not changed the distance from the center of the galaxy during its movement, and therefore, the conditions on Earth do not change.
