Astronomers find a star that is 'gliding' across our Milky Way at 6 million km / h, and so this star will leave the Milky Way in 100 million years.
Astronomers from the Australian National University have studied why this star is in such a rush to leave the Milky Way galaxy. The results of their study appear in the Royal Astronomical Society's monthly journal, according to CNN.
This star is moving at a record speed - 10 times more than most other stars in the Milky Way, including our Sun.
'We track and see the star's journey from the center of the Milky Way - it's quite an interesting thing , ' says Gary Da Costa, research author and professor at the Australian National University. know.

Scientists believe that the star was 'kicked' off the edge of the Milky Way galaxy from the central black hole , called Sagittarius A *, which is 4.2 million times more massive than our Sun.
More specifically, this phenomenon is why the pair is so close to the black hole . Double stars are two stars that move around each other.
'When a double star gets too close to a black hole, the black hole can capture a star into orbit near the black hole and' kick 'the other star away at a very high speed ,' said Thomas Nordlander, co-author of the study and a professor at the Australian National University.
The star is 29,000 light-years from Earth and is 'kicked' out of the black hole Sagittarius A * 5 million years ago.
'On an astronomical scale, the star will soon leave the Milky Way and forever walk in the void between galaxies,' said Da Costa.
'It's nice to be able to confirm the 30-year theory that the star could be' kicked 'out of the galaxy by the supermassive black hole at the center of the galaxy.'
The center of galaxies is an area where it is difficult to see precisely. So, understanding the properties and composition of the 'kicked' star from the center of the galaxy will provide more information about this obscure region.
