Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing new data from NASA’s Fermi Gamma-ray Space Telescope has detected a halo of high-energy gamma rays that closely matches what theories predict should be released when dark matter particles collide and annihilate. The energy levels, intensity patterns, and shape of this glow align strikingly well with long-standing models of weakly interacting massive particles, making it one of the most compelling leads yet in the hunt for the universe’s invisible mass.
