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.

A panel met at SLAC National Accelerator Laboratory to look for promising routes to the study of dark matter, dark energy and other phenomena.

How is it possible to look at the earliest moments of the universe?

Public lecture presented by Julie Hlavacek-Larrondo

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.

In scientific circles, “mock” is not always a four-letter word. To test that they’re interpreting their massive amounts of data correctly, astrophysicists create even more data: “mock” data. And while that may be counterintuitive at first, it actually makes a...

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.

On Dec. 2-4, scientists from around the United States will meet at SLAC to discuss some of the most pressing scientific questions in particle physics and the experiments needed to answer them. You’re invited!

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.

Particle astrophysicists are helping illuminate the dark side of the universe for a new show at the American Museum of Natural History in New York City.

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.
