Prototype tests of the future SuperCDMS SNOLAB experiment are in full swing.

SLAC and Stanford astrophysicists made crucial contributions to the galaxy survey, showing that the universe clumps and expands as predicted by our best cosmological models.

A unique groundbreaking ceremony marked the start of construction of the Long-Baseline Neutrino Facility – future home of the Deep Underground Neutrino Experiment, which promises to shed new light on how the universe works and why matter exists.

The era of multi-messenger astronomy promises rich rewards—and a steep learning curve.

A NASA rocket experiment could use the Doppler effect to look for signs of dark matter in mysterious X-ray emissions from space.

In honor of Fermilab’s upcoming 50th birthday, Symmetry presents physics birthday cards.

Sensitive gamma-ray “eye” on NASA’s Fermi space telescope continues to provide unprecedented views of violent phenomena in the cosmos.

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.
