SLAC and Stanford astrophysicists made crucial contributions to the galaxy survey, showing that the universe clumps and expands as predicted by our best cosmological...

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

In its infancy, the universe was awash in fundamental particles. Over billions of years, matter cooled and clumped into stars and galaxies, tied together by a cosmic web of dark matter.

To explore the birth of the universe, the formation of stars and galaxies and the fundamental structure of space and time, SLAC researchers develop cutting-edge technologies for sensitive experiments located deep underground, on the surface and in space.
