The world's brightest X-ray source sprang to life last week at the U.S. Department of Energy's SLAC National Accelerator Laboratory.

SLAC National Accelerator Laboratory is home to a two-mile linear accelerator—the longest in the world. Originally a particle physics research center, SLAC is now a multipurpose laboratory for astrophysics, photon science, accelerator and particle physics research.

With the greatest total energy, the fastest motions, and the highest-energy initial emissions ever before seen, a gamma-ray burst recently observed by the Fermi Gamma-ray Space Telescope is one for the record books.

Physicists have set a new world record for the smallest writing, with features of letters as small as 0.3 nanometers, or roughly one third of a billionth of a meter.

A keystone of evolutionary history, the Thermopolis Archaeopteryx fossil, has come to the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory to undergo a revolutionary type of analysis.

About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. This object, known as a pulsar, is the first one known to "blink" only in gamma rays, and was discovered by the Large Area...

The U.S. Department of Energy (DOE) has renamed Stanford Linear Accelerator Center the SLAC National Accelerator Laboratory.

The U.S. Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays.

Thirty years ago, particle physics delighted in discovering the "bottomonium" family—the set of particles that contain both a bottom quark and an anti-bottom quark but are bound together with different energies.

After their journey into the cold reaches of space, instruments on the Gamma-ray Large Area Space Telescope have been woken up ready to begin operations.
