The Dark Energy Spectroscopic Instrument begins final testing, setting the stage for a 5-year survey that will analyze the light of 35 million galaxies.

Scientists are designing a next-generation experiment to map the Big Bang’s relic afterglow.

A SLAC/Stanford study of the population of satellite galaxies orbiting the Milky Way provides new clues about the particle nature of dark matter.

Four large meshes made from 2 miles of metal wire will extract potential signals of dark matter particles.

SLAC completed its work on ComCam, a commissioning device to be installed in Chile later this year.

Building the Large Synoptic Survey Telescope also means solving extraordinary technological challenges.

The Large Synoptic Survey Telescope will track billions of objects for 10 years, creating unprecedented opportunities for studies of cosmic mysteries.

Scientists, including researchers at SLAC, have only just begun to study the remarkably detailed map they created of a portion of the sky.

Our best model of particle physics explains only about 5 percent of the universe.

To keep up with an impending astronomical increase in data about our universe, astrophysicists turn to machine learning.

Astrophysicists use a catalog of extended gamma-ray sources spotted by Fermi spacecraft to home in on mysterious properties of deep space.

The event attracted 124 participants and explores the successes and challenges of the theory that describes subatomic particles and fundamental forces.
