For example, our nearest neighbour, the
Andromeda galaxy, devoured galaxies weighing nearly 30 times more than those consumed by the Milky Way.
The timing of the merger may also explain the thickening of the disk of the
Andromeda galaxy as well as a burst of star formation two billion years ago, a finding which was independently reached by French researchers earlier this year.

Large galaxies generally have a retinue of dwarf galaxies orbiting them, and the
Andromeda Galaxy shows two in the same low-power field.
At 2.5 million light years from our own galaxy (the Milky Way) the
Andromeda Galaxy is our closest giant neighbour.

Our Milky Way galaxy may be on a crash course with the

To be nearly visible to the unaided eye from the vast distance of the
Andromeda galaxy, it had to be enormously more luminous than the run-of-the-mill novas that had been seen since Kepler's time.
