What happened

Rubin Observatory opens a deep window on a famous cosmic field Swati Mestri Scientific Editor Robert Egan Senior Editor A new Vera C.

Why it matters

Rubin Observatory image featuring hundreds of thousands of distant galaxies in and around the COSMOS field marks the observatory's first LSST Camera image and catalog release for science.

Common ground

Packed into this single image from Rubin Observatory are many different kinds of galaxies: spirals with delicate arms, smooth elliptical galaxies, distorted merging galaxies, and faint red galaxies from the distant universe.
