Astronomers Found Star Stream 115 Million Light-Years Away That Could Unlock Dark Matter

A thin ribbon of stars in a distant galaxy is the first stellar stream seen outside the Milky Way, and it could help map invisible dark matter. The post Astronomers Found Star Stream 115 Million Light-Years Away That Could Unlock Dark Matter appeared first on StudyFinds.

Astronomers detect first stellar stream from a globular cluster outside the Milky Way

Astronomers have detected the first stellar stream associated with a globular cluster outside the Milky Way. The structure, named Oyashio, was found in the ultra-faint galaxy UGC 9050-Dw1 and formed as tidal forces stripped stars from a dense cluster. This discovery provides researchers with a new method to estimate the mass of dark matter halos in such systems. The Oyashio Stream Stellar streams are elongated structures created when a more mass…
