Galactic Thief

The 11 most distant stars in our galaxy lie about 300,000 light-years from Earth, stretching far outside the Milky Way’s spiral disk.

But half of these stars might not even belong to the Milky Way.

They have been ripped from another galaxy, the Sagittarius dwarf, according to a new study, captured by our galaxy’s immense gravity.

The stars belong to an extending arm one million light-years across space, or 10 times the width of our galaxy, flung out by our galaxy.

But there could be many more, the researchers have said.

‘The star streams that have been mapped so far are like creeks compared to the giant river of stars we predict will be observed eventually,’ said lead author Marion Dierickx, from the Harvard-Smithsonian Center for Astrophysics (CfA).
