Dark Energy Survey scientists have released a detailed map of dark matter – crucial information for a better understanding of galaxy formation and dark energy.

Reports by groups including Dark Energy Survey and Large Area Telescope scientists may provide new clues about the properties of mysterious dark matter.

Two recent meetings at SLAC brought together experts working on computer hardware and software for LSST – a future telescope that will provide unprecedented views of the sky and may solve some of the biggest mysteries of the universe.

When SuperCDMS SNOLAB turns on in 2018 at the underground science laboratory in Canada, it will be able to see dark matter particles 10 times lighter than previous searches.

Plans to build the world’s largest digital camera at SLAC have reached a major milestone, with funding approval for the 3,200-megapixel camera. The camera will be the centerpiece of the Large Synoptic Survey Telescope (LSST), which will provide unprecedented details...

LSST Will Capture Unprecedented View of Night Sky

With two SLAC researchers in the lead, an analysis of the enigmatic Fermi bubbles has narrowed down the number of possibilities for their origin, but hasn't completely solved the puzzle.

About 550 visitors from all over the Bay Area came to explore a wide range of the institute’s cosmic research topics.

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...

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.

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.
