What’s in store for the Milky Way? Thanks to astronomers at the University of Sheffield, scientists may now be better able to answer this questions after solving an enduring puzzle related to the evolution of galaxies. Their findings are detailed in the journal Nature.
The supermassive black holes in the cores of some galaxies drive sizable outflows of molecular hydrogen gas. Consequently, much of the cold gas is discharged from the galaxies. Since cold gas in needed to develop new stars, this directly impacts the galaxies’ evolution.
