70 Ancient Dusty Galaxies at the Edge of the Universe Could Rewrite Cosmic History
A massive international collaboration using the James Webb Space Telescope and ALMA has identified 70 dusty galaxies from the universe's first billion years. These ancient objects appear to have formed stars far earlier than current models predict, potentially forcing a fundamental reassessment of how galaxies evolve.
Key Takeaways
- 48 astronomers from 14 countries identified 70 dusty galaxies from the universe's first billion years using JWST and ALMA
- The galaxies show surprising levels of metals and dust, suggesting multiple generations of stars had already lived and died
