Cause of Galactic Death: Strangulation

Cause of Galactic Death: Strangulation

As murder mysteries go, it's a big one: how do galaxies die and what kills them? A new study, published today in the journal Nature, has found that the primary cause of galactic death is strangulation, which occurs after galaxies are cut off from the raw materials needed to make new stars.
