The Milky Way May Already Be Colliding With Another Galaxy

A team of scientists have used Hubble to discover that our galaxy the Milky Way could already be in the process of colliding with another galaxy.

Nicolas Lehner of the University of Notre Dame, Indiana and his team discovered a giant invisible halo of gas around our nearest neighbour the Andromeda galaxy.

While they knew about the halo before, what they didn’t realise was just how large it was. It’s enormous, 1000 times more enormous in fact than previously thought.

By using this data, the team were able to predict that our own galaxy probably has this same halo effect. If true, that means the Milky Way and Andromeda galaxies could already be touching, pre-empting a collision that wasn’t due to start for around 4 billion years.
