A ghostly ribbon of stars reveals hidden dark matter
SMRTR summary
Astronomers have spotted the first stellar stream outside the Milky Way, a faint ribbon of stars shed by a dissolving cluster in the galaxy UGC 9050-Dw1, located 115 million light-years away. By running thousands of computer simulations, researchers used the stream's shape to map dark matter's distribution in the galaxy. This technique could eventually be applied across many galaxies, deepening our understanding of dark matter's fundamental nature.
