The Particle Physics Project Prioritization Panel’s recommendations will set the course for the future of particle physics in the United States.

Scientists say collisions between dark matter particles might be the cause of a curious excess of gamma-ray light coming from the center of our ga

Scientists studying five years of data from the Fermi Gamma-ray Space Telescope have found the first gamma-ray variable pulsar.

Using an entire galaxy as a lens to look at an object in the far distance, researchers are learning more about powerful jets emitted when matter f

Editors of the journal Science, published by the American Association for the Advancement of Science, have selected their annual Top 10 Science Breakthroughs of the Year. On the list: Work by SLAC researchers pinning down the origin of cosmic rays.

SLAC's Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) recently hosted many of the top scientists in the field to discuss the most important questions to confront in the coming decade.

As volunteers for a project called Einstein@Home, citizen scientists unleashed the unused cycles of their home computers on data from the Large Area Telescope, the SLAC-operated main instrument of the Fermi Gamma-ray Space Telescope, and found four new pulsars.

SLAC and Stanford physicists played a key role in monitoring and analyzing the brightest gamma ray burst ever measured, and suggest that its never-before-seen features could call for a rewrite of current theories.

Scientists in SLAC's Integrated Circuits Department reach a new frontier in ultrafast X-ray science with intricately designed signal-processing chips that translate particles of light into bits of data.

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...

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

Two SLAC-affiliated professors were recently elected members of the American Academy of Arts and Sciences.
