• 48 astronomers from 14 nations uncover dusty, star‑forming galaxies at universe’s edge. • These galaxies formed just one billion years after the Big Bang, 13.7 billion years ago. • They may bridge the gap between ultradistant bright galaxies and early quiescent galaxies. • The discovery offers a snapshot of galaxy evolution in the universe’s first billion years. • Findings highlight the role of dust in early star‑forming galaxies. • Research led by University of Massachusetts Amherst showcases international collaboration.
Article Summaries:
- A team of 48 astronomers from 14 countries, led by the University of Massachusetts Amherst, has discovered a population of dusty, star-forming galaxies at the far edges of the universe that formed only a billion years after the Big Bang, believed to have occurred 13.7 billion years ago. The galaxies may represent a snapshot in the galactic life cycle, linking recently discovered ultradistant bright galaxies formed 13.3 billion years ago with early “quiescent” (dead) galaxies that stopped forming stars about two billion years after the Big Bang.
