Are there dark doings near the center of the Milky Way? That may be so when it comes to the collision of dark matter particles. Although such particles are invisible, we could still theoretically see the mess they make when they collide. It’s this idea that leads physicists to scour the galaxy for some glimmer of dark matter collisions. Spot a line produced by a pair of gamma-rays emanating from just the right spot and you may have found coveted clues to the dark matter mystery.

Now a collaboration of scientists using the Fermi Gamma-Ray Spacecraft’s Large Area Telescope instrument (Fermi–LAT) has confirmed seeing an unusual gamma-ray line near the galactic center. If the finding stands up to further scrutiny, it’s possible this line comes from the annihilation of dark matter.
