James Webb telescope reveals 'Sleeping Beauty' galaxies in the early universe — snoozing where they weren't supposed to exist

Using data from the James Webb Space Telescope, astronomers have discovered dormant galaxies with a wide range of masses in the first billion years after the Big Bang, moving one step closer to understanding how early galaxies grow.

James Webb Discovers 'Sleeping Beauty' Galaxies in the Early Universe

The discovery of dormant galaxies, located in the first billion years after the Big Bang, is shaking up our understanding of galaxy evolution. This remarkable finding comes from the cutting-edge observations made by the James Webb Space Telescope (JWST), which revealed galaxies that had ceased their star formation at an unexpectedly early stage in the universe’s history. While these galaxies are thought to be in a brief “quiet phase,” they offer…
