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.
The COSMOS field, or Cosmic Evolution Survey Deep Field, is one of the most famous patches of the universe observed by astronomers.
The short version
- 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.

What happened
Editors have highlighted the following attributes while ensuring the content's credibility: The COSMOS field, or Cosmic Evolution Survey Deep Field, is one of the most famous patches of the universe observed by astronomers. Astronomers have studied the COSMOS field for more than two decades, directing many of the world's leading telescopes to observe it in different wavelengths (optical, radio, ultraviolet, X-rays, etc.).
Why it matters
Because it is so well studied, it has served as a reference point for testing new instruments, comparing measurements and combining observations.
