Rubin Observatory Debuts Deep-Sky Mosaic Covering 500,000 Galaxies

The Rubin Observatory released its first science image from the LSST, a deep view of the COSMOS field featuring more than 500,000 galaxies (and about 50,000 foreground stars) captured with the 3.2-gigapixel LSST Camera. Part of Early Data Preview 2, the image previews the decade-long Legacy Survey of Space and Time and will be followed by repeated observations to study galaxy evolution and transient events like supernovae, building what scientists describe as the most comprehensive cinematic record of the universe.

Rubin Observatory Captures 650,000 Galaxies in a Single COSMOS View

A new Rubin Observatory image of the COSMOS field captures more than 650,000 galaxies and 50,000 stars in a single deep view, thanks to its 3.2-gigapixel camera. Rubin will image this patch repeatedly over its decade-long LSST survey, enabling comparisons with Hubble and Webb and advancing studies of dark matter, dark energy, supernovae, and near-Earth asteroids.

3.2-gigapixel Rubin image maps over half a million galaxies in COSMOS field

Astronomers using the Vera C. Rubin Observatory released a stacked 3.2‑gigapixel image of the COSMOS field—the deepest wide view of the sky to date—captured with the LSST Camera on the 8.4‑meter telescope. By stacking hundreds of exposures, the image reveals more than 500,000 galaxies and over 50,000 stars, with the foreground Milky Way stars providing contrast. This Early Data Preview 2 (EDP2) from Rubin’s Legacy Survey of Space and Time (LSST) marks the first data release from Rubin’s decade‑long survey and will enable studies of cosmic evolution and transient events like supernovae as more data are collected over time.
