Hubble Uncovers Multi-Age Stars in Ancient Cluster, Reshaping Galaxy Origins

Astronomers call ancient star clusters like NGC 1786 “time capsules” for their galaxy, preserving some of its oldest stars. A new image from NASA's Hubble Space Telescope offers an unprecedented close-up of this dense cluster 160,000 light-years away in the Large Magellanic Cloud. Hubble's data show that NGC 1786 contains stars of different ages – a surprising find, since such clusters were once thought to hold a single stellar generation. This multi-age discovery is reshaping our view of how galaxies built their first stars, and suggests more complex early history. Mixed-Age Stars in a Galactic Time Capsule According to the official source, this Hubble image shows the globular cluster NGC 1786, a ball of densely packed stars in the Large Magellanic Cloud about 160,000 light-years from Earth. Astronomers captured this picture as part of a program comparing ancient clusters in nearby dwarf galaxies (like the LMC) with clusters in our own Milky Way. The surprising discovery is th...
