Galactic Center GeV excess

The Galactic Center GEV excess is a mysterious area of the sky that glows brighter than it should in certain kinds of light. Scientists think that it might be caused by dark matter, which is a kind of matter that we can't see but that we think might make up most of the stuff in the universe. The light from the Galactic Center GEV excess might help scientists learn more about dark matter and how it works.
