Dwarf Galaxy 3

Star trails take shape around the 14-story Mayall Telescope dome in this long-exposure image.

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

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.

Spacetime and quantum mechanics are the pillars of our modern understanding of fundamental physics.

Presented by Eric Charles. A single gamma ray carries millions of times the energy of a single photon of visible light. This means that gamma rays are produced only in the most convulsive environments in the universe – pulsars spinning...

Spacetime and quantum mechanics are the pillars of our modern understanding of fundamental physics. But there are storm clouds on the horizon indicating that these principles are approximate, and must be replaced with something deeper. The union of quantum mechanics...
