Something mysterious is lighting up the Milky Way. Could it be dark matter?

Scientists at Johns Hopkins may be closing in on dark matter’s elusive trail, uncovering a mysterious gamma ray glow at the heart of our galaxy that could signal unseen matter colliding — or perhaps the frantic spin of dying stars. Using advanced simulations that account for the Milky Way’s ancient formation, researchers found a near-perfect match between theoretical and observed gamma ray maps, tightening the link between dark matter and this puzzling energy. Yet the mystery remains: could these signals come from millisecond pulsars instead?
