Astronomers Identify First Extragalactic Globular Cluster Stellar Stream

Astronomers have identified the first globular cluster stellar stream outside the Milky Way, named Oyashio, unraveling around galaxy UGC 9050-Dw1 using archival Hubble images. This discovery provides a novel method to map invisible dark matter in distant galaxies, validating theoretical expectations and enhancing our understanding of galactic structure and evolution.
