Star Stream
Featured on June 18, 2021
A computer simulation shows several streamers of stars flowing outside the disk of the Milky Way Galaxy. The recently discovered Jhelum Stream is in orange. Its stars may be the remnants of a small galaxy or a star cluster that was ripped apart by the Milky Way's powerful gravity. The stream is in the Milky Way's halo, which surrounds its bright disk.
