Rubin observatory peers deep into the famous COSMOS field

The COSMOS field, or Cosmic Evolution Survey Deep Field, is one of the most famous patches of the universe observed by astronomers. Located in the constellation Sextans, this region was photographed by the Hubble Space Telescope (HST) in segments from 2003 to 2005 using its Advanced Camera for Surveys (ACS). With support from ground-based and other space-based telescopes, the resulting images were then stitched together to create a stunning picture of cosmic evolution.
