Galactic Collision Now on Video

Scientists have long known that the nearby galaxy Andromeda and our own Milky Way galaxy will collide in four to five billion years, but now a new computer simulation from the International Centre for Radio Astronomy Research in Western Australia shows what the colossal crash may look like.

The simulation is part of new research showing that massive galaxies like Andromeda tend to grow by cannibalizing smaller galaxies.

This should be fun:

An article describing the research was published online in the Monthly Notices of the Royal Astronomical Society on September 18, 2014.
