Story summary

A new study suggests the Galactic Center Excess (GCE) glow could indicate dark matter, increasing likelihood but not proof.
The GCE was detected by NASA's Fermi Gamma-ray Space Telescope in 2009, puzzling scientists since.
Researchers' simulations show dark matter distribution could explain the GCE's shape, previously thought to favor pulsars.
Future observations from the Cherenkov Telescope Array, set to begin in 2027, may clarify the glow's source.
