As smaller galaxies collide with our own they’re slowly torn apart. By watching how they spread across the night’s sky we can infer an incredible amount about the shape of the galaxy and the nature of dark matter.
Astronomers have recently discovered a number of galaxies made almost entirely of dark matter. Today’s astrobite takes a closer look at one of them.
In the latest post on our sister site Particlebites, Chris Karwin writes about new observations of the gamma ray excess at the Galactic center from Fermi.
Today we feature a recent article from our sister site particlebites exploring new theory on dark matter interactions,

Since discovered last year, the origin of a disproportionate amount of extreme heavy elements in a dwarf galaxy has been a mystery. Could it be the work of an invisible hand?
