A star was found traveling through our galaxy at 3.7 million miles an hour and scientists had questions. After trying to piece it together, they realized that the star had actually come too close to a gigantic black hole at the center of our galaxy and was propelled, as if by a slingshot, out of the galaxy.
Scientists were delighted to discover a star within our own galaxy to have been propelled by a black hole. According to the lead author of the study:
This is super exciting as we have long suspected that black holes can eject stars with very high velocities. However, we never before had a clear association of such a fast star with the Galactic Centre.Professor Koposov
Currently the star, known as S5-HVS1 is only about 29,000 light years away from us but was in the center of our galaxy at one point. To put this in perspective, here are some comparisons of speed:
As you can see, Earth’s fastest plane, which travels at 2,193 mph does not even chart. Even Oumuamua, the super mysterious interstellar comet that shot through our solar system last year does not remotely approach it and that is the fastest object we have seen from Earth with normal telescopes.
