An excess of gamma rays at the center of the Milky Way, previously discussed as a sign of dark matter, is likely caused by the superdense remains of ancient stars.

Astrophysicists Eric Charles and Mattia Di Mauro discuss the surprising glow of our neighbor galaxy.

Three recent studies using data from the Fermi Gamma-ray Space Telescope have expanded the hunt for unexplained signals coming from beyond our galaxy.

The center of our galaxy is a busy place. But it might be one of the best sites to hunt for dark matter.

Dark matter hunters around the world pursue three approaches to look for fingerprints of ghostly WIMPs: on the Earth’s surface, underground and in space.

Fermi scientist Matthew Wood discusses major improvements to the Fermi Large Area Telescope, including increasing its sensitivity to the equivalent of launching another LAT.

A recent uptick in the discovery of the smallest, oldest galaxies benefits studies of dark matter, galaxy formation and the evolution of the unive

Observations of this kind could lead scientists to the source of ultra-high-energy cosmic rays.

The Fermi Gamma-ray Space Telescope creates maps of the gamma-ray sky.

A batch of newly discovered satellite dwarf galaxies orbiting the Milky Way should help scientists better grasp the evolution of the universe while also honing in on dark matter's identity.

Indirect detection experiments might be the key to discovering invisible dark matter.
