The latest results put the strongest constraints on the expansion of the universe ever obtained with DES supernova data.

A new experiment suggests that this exotic precipitation forms at even lower pressures and temperatures than previously thought and could influence the unusual magnetic fields of Neptune and Uranus.

Margaux Lopez is helping prepare the Vera Rubin Observatory for the arrival of the largest digital camera ever built for astrophysics and cosmology.

Supermassive black holes at the hearts of distant galaxies – and even our own sun – shine in the new movie. 

The High Energy Physics Advisory Panel has approved the recommendations of the P5 Report.

A new report outlines suggestions for federal investments needed for the next generation of transformative discoveries in particle physics and cosmology, including priority projects at SLAC.

SLAC will partner in two collaborations that aim to speed up progress in fusion energy science and technology.

Vera C. Rubin Observatory’s fast-moving telescope and huge digital camera will illuminate the faint glow of free-floating stars within galaxy clusters, providing unprecedented insight into the evolution of these dynamic structures.

Four engineers discuss their journeys to working at SLAC and counsel those following in their footsteps.

Three SLAC scientists explain what they do to ensure the world's largest digital camera for astronomy is ready for the big time.

With up to a million X-ray flashes per second, 8,000 times more than its predecessor, it transforms the ability of scientists to explore atomic-scale, ultrafast phenomena that are key to a broad range of applications, from quantum materials to clean...

Line intensity mapping measurements taken with a new instrument will allow astrophysicists to study galaxies too far away for traditional methods.
