A Glowing Mystery at Our Galaxy's Center Has a Mind-Blowing Explanation, Physicists Believe

AdvertisementDi Mauro is not the first to suggest that dark matter might account for the unexplained gamma rays, which are collectively known as the Galactic Center GeV Excess (GCE). But in 2009, scientists combing through observations made by NASA’s Fermi space telescope noticed that the galactic center was much brighter in high-energy gamma ray radiation than any models had predicted. Though nobody has seen light emitted by this enigmatic material, scientists have spent many years searching for luminous by-products of so-called “dark matter annihilations,” events that could finally unmask the true nature of dark matter. However, the sheer complexity of the galactic center, combined with the frustratingly elusive nature of dark matter, should temper our expectations that this puzzle will be solved anytime soon. Update: The story has been updated to include comments from study author Mattia Di Mauro.
