Astronomers at Texas A&M University have discovered a rare, tightly packed collision of galaxies in the early universe, suggesting that galaxies were interacting and shaping their surroundings far earlier than scientists had predicted. Using observations from the James Webb Space Telescope (JWST), the researchers identified an ongoing merger event of at least five galaxies about 800 million years after the Big Bang, along with evidence that the collision was redistributing heavy elements beyond the galaxies themselves.
