List of stellar streams

Stellar streams in the Milky Way, discovered in 2007

This is a list of stellar streams. A stellar stream is an association of stars orbiting a galaxy taking the appearance of an elongated stream of stars. Stars that are part of stellar streams were often once part of a globular cluster or dwarf galaxy. However, their original system has now been torn apart and stretched out along its orbit by the tidal forces of the larger galaxy. An exception in the list about Milky Way streams given below is the Magellanic Stream, composed of gas (mostly hydrogen), although in 2023, a population of stars has been described inside it.
