Scientists from the Kavli Institute for Particle Astrophysics and Cosmology are helping build cameras for the Cherenkov Telescope Array, an advanced, ground-based gamma-ray observatory.

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

The Cosmic Microwave Background, leftover light from the big bang, carries a wealth of information about the universe—for those who can read it.

Two scientists at Stanford University and SLAC National Accelerator Laboratory made key contributions to the discovery of the first direct evidence for cosmic inflation – the rapid expansion of the infant universe in the first trillionth of a trillionth of...

Researchers from the BICEP2 collaboration have announced the first direct evidence supporting the theory of cosmic inflation. Their data also represent the first images of gravitational waves, or ripples in space-time. These waves have been described as the "first tremors...

Particle Fever is a documentary that follows scientists involved in research at the Large Hadron Collider, including the ATLAS Experiment in which SLAC participates. The film opens this week in select theaters across the United States.

Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system...

In a SLAC test facility, scientists have set the stage for an experiment that mimics what happens when incredibly energetic cosmic ray particles hit our atmosphere. While the experiment is part of ANITA, which sends balloon-borne instruments into the upper...

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

The distant universe looks a little clearer, thanks to tens of thousands of citizen scientists who classified more than 6 million images over the past three days.

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.
