Observations of dwarf galaxies around the Milky Way have yielded simultaneous constraints on three popular theories of dark matter.

Blandford’s major contributions range from energetic jets ripping forth from colossal black holes to cosmic “magnifying” glasses to gravitational waves.

Physicists at SLAC and Stanford propose that the influence of cosmic rays on early life may explain nature’s preference for a uniform “handedness” among biology’s critical molecules.

The SLAC/Stanford scientists are among 120 new members of an organization that advises the nation on science and technology issues.

Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100...

Matching up maps of matter and light from the Dark Energy Survey and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint cosmic gamma-ray glow.

The Large Synoptic Survey Telescope will be named for an influential astronomer who left the field better than she found it.

As the massive LSST camera project reaches its culmination, Hannah Pollek is one of the engineers in the clean room each day putting the pieces together.

His work aims to deepen our understanding of dark matter, dark energy and other secrets of the universe.

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.

Early-career physicist Jonathan LeyVa helps build one of the world’s most sensitive dark matter detectors.

An “out there” theory inspired the development of the Dark Matter Radio, a device that could explain the mysterious matter that makes up 85 percent of the mass of our universe.
