Overview
- The peer-reviewed COSMOS-Web study maps large-scale structure across 164,000 galaxies reaching back to about one billion years after the Big Bang.
- The survey spans a contiguous patch of sky about the size of three full Moons and stands as JWST’s largest General Observer program.
- Compared with Hubble views of the same region, the new data resolve multiple filaments that earlier images blurred into single structures.
- Sharper maps come from detecting many more faint galaxies and placing them in tighter time slices using more precise distance measurements.
- The team has released the pipeline, galaxy catalog, density maps, and an evolution video to the public, and reports early signs that the web shapes growth and may suppress star formation in older galaxies.
