A Star Ejected from the Milky Way's 'Heart of Darkness' Has Reached a Mind-Blowing Speed

As humankind's ancestors were learning to walk upright, a star was launched out of the supermassive black hole at the center of our galaxy at a staggering 3.7 million mph (6 million km/h).

Five million years after this dramatic ejection, a group of researchers, led by Sergey Koposov of Carnegie Mellon University's McWilliams Center for Cosmology, has spotted the star, known as S5-HVS1, in the Crane-shaped constellation Grus. The star was spotted traveling relatively close to Earth (29,000 light-years away) at unprecedented, searing speeds — about 10 times faster than most stars in our galaxy.

"The velocity of the discovered star is so high that it will inevitably leave the galaxy and never return," Douglas Boubert, a researcher at the University of Oxford and a co-author on the study, said in a statement.

"This is super exciting, as we have long suspected that black holes can eject stars with very high velocities. However, we never had an unambiguous association of such a fast star with the galactic center," Koposov said in the statement.

1. Too bad we can't eject tRump out of the Oval Office that fast.

Boom! Straight out into space and to infinity! 💫🌟💥

2. Thanks for the hearty chuckle....still chuckling.nt

3. He sees himself as a star. We'll just need a smaller Black Hole to roll up to the White House

to put him far enough away we can't hear him any longer, or read his nasty tweets.

Should keep it on hand for any stragglers, at a later time.

4. Amazing!

The wonders of the universe never cease to impress. it's incredible to think something could be ejected with such force that it leaves the galaxy.

Thanx for posting.

6. Even harder to image black holes than it was before now. Thanks. n/t

5. STAR SPOTTED FLYING THROUGH UNIVERSE AT BLISTERING SPEED AFTER BEING THROWN OUT BY BLACK HOLE

A star has been spotted speeding through the universe after it was thrown by a supermassive black hole.

It is going so fast that it will eventually be thrown out of the galaxy and never return, scientists said.

The star was thrown out of the black hole at the centre of our galaxy, known as Sagittarius A*. As such, scientists describe it as "a visitor from a strange land", having come relatively near to us from the very middle of our Milky Way.

The star was spotted in the constelltion of Grus, or the crane, by researchers from Carnegie Mellon University. They saw that the star was moving 10 times faster than most of the stars in our galaxy, and looked to study it for more information.

"The velocity of the discovered star is so high that it will inevitably leave the galaxy and never return," said Douglas Boubert from the University of Oxford, a co-author on the study.

High velocity stars of this kind were only discovered about 20 years ago, and remain mysterious to scientists. This is the first star of its kind ever seen, with astronomers never spotting one of the mysterious stars so fast and close by before.

7. Imagine living on a planet in orbit around that star

Known ng one day your world will be alone in the void between galaxies.
