Scientists baffled by huge mysterious hole in Milky Way

Scientists have been left baffled by a giant hole in the Milky Way's Halo, reports Newsweek. But researchers at Harvard University, in the United States, have put forward some theories about how it may have happened.

One possibility, is that it was created by some massive impact that 'punched' through the Halo, but the object would need to have a mass - a million times bigger than our own Sun. Mysteriously, there is nothing in our galaxy which comes near to that.

Other theories have included a possible super-massive black hole, but researchers believe that this would have been detected due to its massive gravitational presence.

Studies continue to try to determine what may have ripped a gapping hole in the halo at the centre of our galaxy.
