SLAC scientists played key roles in leadership, survey design, cosmological  applications, studies of dark matter and of links to the cosmic microwave background.

An international team of researchers simulated magnetic forces in the early universe and found they could bridge the gap between the observed and calculated rates of the universe’s expansion.

NSF-DOE Rubin Observatory has issued its first scientific alerts, marking a historic milestone in astrophysics and kicking off a new era of dynamic, real-time observation of the night sky.

The team developed a platform that uses powerful X-rays from the lab’s LCLS X-ray laser to resolve for the first time the evolution of instabilities in high-density plasmas. 

The latest results combined weak lensing and galaxy clustering and incorporated four dark energy probes from a single experiment for the first time.

First peer-reviewed paper using data from SLAC-built LSST Camera identifies an asteroid, nearly the size of eight football fields, rotating every two minutes.

The state-of-the-art ‘big-data facility’ unveils its first images and video, bringing the night sky to life like never before.

NSF–DOE Vera C. Rubin Observatory is about to embark on its quest to capture the cosmos, marking the culmination of decades of work by thousands of people across the globe.

NSF–DOE Vera C. Rubin Observatory will add an unprecedented amount of cosmological data to the study of the structure and expansion of the Universe.

A look inside the data processing infrastructure built by the NSF–DOE Vera C. Rubin Observatory to handle the Universe’s greatest data challenge.

Now that NSF–DOE Vera C. Rubin Observatory’s LSST Camera has been installed, what’s next?

Using the largest digital camera in the world, Rubin Observatory will soon be ready to capture more data than any other observatory in history.
