Milky Way on ‘collision course’ with nearby ‘monster’ galaxy
[NYPOST] The home to all life as we know it, the Milky Way galaxy, is on a “collision course” with its cosmic neighbor, Andromeda, according to a new study.
That does it! I'm leaving!
But you needn’t fret, astronomers say — it won’t happen for about 4.5 billion years.
You mean I have time to pack?
The research noted that Andromeda’s size, significantly larger than the Milky Way, likely makes it a “cannibalistic” neighbor, swallowing up more galaxies in its past than it was previously given credit for.
A rogue galaxy? What will they come up with next?
“The Milky Way is on a collision course with Andromeda in about four billion years. So knowing what kind of a monster our galaxy is up against is useful in finding out the Milky Way’s ultimate fate,” said Australian National University researcher Dougal Mackey in a statement.

“Andromeda has a much bigger and more complex stellar halo than the Milky Way, which indicates that it has cannibalized many more galaxies, possibly larger ones,” Mackey added.
