700 million-year-old REBELS-25, the most distant rotating disc galaxy, was identified, disputing theories of chaotic early galaxies.
Astronomers have identified REBELS-25, the most distant rotating disc galaxy observed, dating back to just 700 million years after the Big Bang. Detected with the Atacama Large Millimeter/submillimeter Array (ALMA), its orderly structure challenges existing theories that early galaxies were chaotic. This finding may reshape our understanding of how galaxies evolved into the organized structures we see today. Further study with the James Webb Space Telescope is anticipated.
