AI Insight
NASA's Hubble Space Telescope has observed LH 95, a stellar nursery containing approximately 2,500 young stars in various stages of formation. Research reveals that these developing stars can continue accumulating gas and dust for millions of years, which extends a critical phase of stellar evolution longer than previously understood. The region exhibits multiple generations of stars coexisting in the same area, providing new insights into the timeline and processes of star formation.
Why it matters
This discovery refines our understanding of how stars form and evolve, particularly the duration of their gas and dust accumulation phase. Observing multiple stellar generations together allows scientists to better reconstruct the chronological sequence of star formation and improve models of galactic evolution.
Understand the Science
Hubble has captured a spectacular view of LH 95, where about 2,500 young stars are still on their journey to becoming full-fledged stars. Scientists discovered these growing stars can keep pulling in gas and dust for millions of years, extending an important stage of stellar development. The region also contains multiple generations of stars living side by side, offering fresh clues about how star formation unfolds over time.
