You are welcome to attend the live stream of NSF–DOE Vera C. Rubin Observatory’s First Look event, taking place on 23 June 2025 at 11:00 a.m. EDT. At this international celebration the Rubin Observatory team will unveil the observatory’s first spectacular images. The event will be live streamed via YouTube in English and Spanish. Links to the live streams will be made available on rubinobservatory.org.

Want to attend an in-person celebration? Hundreds of venues around the globe will be hosting watch parties that include a public viewing of the live stream. Check out the Rubin First Look Watch Party website to find a location near you.

NSF–DOE Vera C. Rubin Observatory is jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy’s Office of Science . 

The First Look event will feature the unveiling of a set of large, ultra-high-definition images and videos that showcase Rubin’s extraordinary capabilities to the world for the first time. This will mark the beginning of a new era in astronomy and astrophysics.

These images and videos will be the first of many that Rubin will release over the course of the next decade as it conducts the Legacy Survey of Space and Time (LSST). Equipped with the world’s largest digital camera, Rubin will sweep the entire visible southern sky every three to four nights. In doing so, Rubin will produce the most detailed time-lapse view of the cosmos that has ever existed.

This unique movie will bring the cosmos to life, yielding a treasure trove of discoveries: asteroids and comets, pulsating stars, and supernova explosions. With Rubin data, we will better understand the Universe, chronicle its evolution, delve into the mysteries of dark energy and dark matter, and reveal answers to questions we have yet to imagine.

Rubin Observatory is a joint Program of NSF NOIRLab and SLAC National Accelerator Laboratory (SLAC), who will cooperatively operate Rubin.
