US EditionLargest Map of the Universe Announced Revealing 800,000 Galaxies, Challenging Early Cosmos Theories
- On June 5, 2025, astronomers from the COSMOS collaboration unveiled the most extensive cosmic map ever created, spanning 0.54 square degrees within the COSMOS field.
- The map was created from 255 hours of James Webb Space Telescope observations to image nearly 800,000 galaxies spanning almost all cosmic time back 13.5 billion years.
- The COSMOS-Web project aimed to reveal early galaxies within their cosmic environments to understand star and black hole formation during the Reionization Era.
- Co-Lead Caitlin Casey highlighted that JWST observations have detected about ten times more distant galaxies than previously anticipated, raising questions about whether these findings challenge existing cosmological models.
- The publicly released map and interactive catalog democratize science, enabling global research while raising new questions about the early universe's rapid star formation.

Largest-ever map of the universe reveals 10x more early galaxies than expected
An international team of scientists has unveiled the largest and most detailed map of the universe ever created using the James Webb Space Telescope, revealing nearly 800,000 galaxies stretching back to almost the beginning of time. The COSMOS-Web project not only challenges long-held beliefs about galaxy formation in the early universe but also unexpectedly revealed 10 times more galaxies than anticipated along with supermassive black holes Hub…
The multinational scientific collaboration COSMOS has published the data supporting the largest map of the universe: a catalogue of nearly 800,000 galaxies covering almost all cosmic time.
Most intricate map of the universe contains nearly 800,000 galaxies stretching back to the dawn of time
The largest map of the universe, created with data from the James Webb Space Telescope, shows almost 800,000 galaxies crammed into a tiny piece of sky and spanning almost all of time.
