In a new study, SLAC researchers suggest a small-scale solution could be the key to solving a large-scale mystery.

Vera C. Rubin Observatory’s detailed, big-picture view of our Solar System and ability to quickly detect and track moving objects will provide a gold mine of data to benefit space mission planning and preparation.

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

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

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.

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.

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

It takes a lot of meetings, travel logistics and even tracking down some parts to keep a large team collaborating on a project like the LSST Camera. That’s where administrator Regina Matter comes in.

The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to mine. Taken during the experiment’s “survey validation” phase, the data include distant galaxies and quasars as well as stars in our own Milky...

Just because matter is visible doesn’t mean it’s easy to see.

An astronomy festival will mark the milestone.

A new study probing the structure and evolution of galaxy clusters shows good agreement with the predictions of standard cosmological models.
