For the first time, researchers have discovered a globular cluster stellar stream in a galaxy beyond the Milky Way – specifically in an ultra-diffuse galaxy. The discovery opens up new possibilities for studying dark matter, one of the greatest unsolved mysteries in modern astrophysics. The finding was made by researchers from the University of Copenhagen and has just been published in Nature.

Deep Hubble Space Telescope imaging of the ultra-diffuse galaxy UGC 9050-Dw1 reveals an extragalactic globular cluster stream, with analysis and modelling probing the rich dark…
