MILKY WAY IS A COSMIC THIEF
New simulations show the Milky Way may have stolen its most distant stars from the Sagittarius dwarf galaxy. Simulations indicate that the dwarf could have lost a third of its stars to ours. Over time this may have created three streams of stars, radiating as far as a million lightyears from the galactic centre. “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,” says Marion Dierickx from the Harvard Smithsonian Center for Astrophysics.
