Question

Quizplus · Accepted Answer

Star streams around the Milky Way Galaxy are likely the result of tidal interactions with satellite galaxies. These interactions can cause tidal tails of stars to form, which appear as streams of stars around the galaxy. Star streams orbiting the Milky Way are most likely caused by the tidal forces of smaller satellite galaxies that have been assimilated by the Milky Way over time.
