Traces of iron spread smoothly throughout a massive galaxy cluster tell the 10 billion-year-old story of exploding supernovae and fierce outbursts from supermassive black holes sowing heavy elements throughout the early cosmos.

On June 11, 2008, what was then the Gamma-ray Large Area Space Telescope rode a Delta II rocket into low-Earth orbit. After two months of tests and checks and calibrations, on August 11, 2008, NASA declared GLAST open for business...

For the 41st annual Particle Physics & Astrophysics Department’s SLAC Summer Institute (SSI), organizers introduced a successful new feature.

Theorists from the Kavli Institute for Particle Astrophysics and Cosmology are helping dark matter sleuths decide where to start their search.

A record-setting blast of gamma rays from a dying star in a distant galaxy has wowed astronomers around the world.

A new study confirms what scientists have long suspected: Cosmic rays – energetic particles that pelt Earth from all directions – are born in the violent aftermath of supernovas, exploding stars throughout the galaxy.

Black holes are the ultimate Bogeyman.

The search for dark matter runs deep with physicists Blas Cabrera and Bernard Sadoulet, who have chased this mystery far underground and will be recognized for their work as joint recipients of the 2013 W.K.H. Panofsky Prize in Experimental Particle...

Menlo Park, Calif. — A 3.2 billion-pixel digital camera designed by SLAC National Accelerator Laboratory is now one step closer to reality.
