Hubble Telescope Detects First Globular Stellar Stream Beyond Milky Way

NASA's Hubble Space Telescope has identified the first extragalactic globular stellar stream, located in the galaxy UGC 9050-Dw1, approximately 115 million light-years away. This faint trail of stars, found in archival data, is believed to be the remnants of a star cluster disrupted by its host galaxy. The discovery offers new methods for mapping a galaxy's mass, including its dark matter distribution, enhancing our understanding of galactic dynamics.
