NSF-DOE Rubin Observatory Opens Deep Window on Famous Cosmic Field

This zoom shows an exceptionally deep image from NSF–DOE Vera C. Rubin Observatory of the renowned COSMOS field and its surroundings in the constellation Sextans. The view is crowded with galaxies and galaxy clusters spanning an immense range of distances and cosmic ages, while only a handful of foreground stars belong to our own Milky Way. It was created by combining multiple observations from Rubin’s LSST Camera into a deep co-added image and is being released to mark Early Data Preview 2, the first Rubin data preview based on LSST Camera observations.
