Milky Way is colliding with another galaxy...

In 1994, UK astronomers discovered a small galaxy just on the other side of our Milky Way galaxy, about to swallowed up by its larger neighbour.

Since then it has become clear that this Sagittarius dwarf galaxy, as it is been called, is actually orbiting over the poles of our own galaxy, with long streams of stars preceding and trailing the main body.

It was when dark matter expert Katherine Freese, from the University of Michigan, heard astronomer Heidi Jo Newberg, from the Rensselaer Polytechnic Institute, talk about these so-called tidal streams that an explanation for the puzzling seasonal Dama Wimp result started to crystallise.
