Physicists from Carnegie Mellon University, Brown University, and Cambridge University have submitted a finding in the journal Physical Review Letters to suggest the discovery of a dwarf galaxy orbiting our Milky Way – and seeming to emit gamma rays, which the team of scientists find rather unusual. However, if anything, they think the high-energy light might just be indicative of some dark matter within the center of the galaxy.

According to Alex Geringer-Sameth, a postdoctoral research associate in CMU’s Department of Physics and the paper’s lead author, “Something in the direction of this dwarf galaxy is emitting gamma rays. There’s no conventional reason this galaxy should be giving off gamma rays, so it’s potentially a ...
