Nearby relic galaxy NGC 1277 may hold clues to universe's first stars

Nearby relic galaxy NGC 1277 may hold clues to universe's first stars

The first stars that formed in the universe remain unseen, despite their obvious existence in cosmic history. These primordial stars were fundamentally different from the ones we observe today: they contained no metals, were extraordinarily massive, and nearly all ended their lives in supernovae. A nearby relic galaxy called NGC 1277 may offer astronomers their best opportunity yet to understand what those earliest generations looked like. Because this ancient galaxy has remained largely unchanged since the early universe, it preserves conditions and stellar populations that more closely resemble the cosmos's first epoch of star formation. Studying its composition, stellar ages, and structure could unlock insights into how the first stars ignited, evolved, and eventually seeded heavier elements throughout space. The search has become one of modern astronomy's most tantalizing puzzles: we know the first stars must have existed, but direct observation has eluded us.
