Astronomers Discover a Ghostly River of Stars That Could Reveal Dark Matter
Reported bySciTechDaily ↗·Sourced by Goodlede
An international team led by researchers from the University of Copenhagen and Technical University of Denmark identified the first known globular cluster stellar stream in another galaxy, a ribbon of stars around the ultra-diffuse galaxy UGC 9050-Dw1 located 115 million light-years away, discovered in archival Hubble Space Telescope images and reported in Nature.
The stellar stream itself is observable; the dark matter it may reveal remains to be fully characterized through further gravitational modeling.
