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...

Teachers are using Google+ to bring their classes behind the scenes at national laboratories and to teach students about careers in STEM.

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.

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

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.

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.
