List of stellar streams

A stellar stream is an association of stars orbiting a galaxy.

It was once a globular cluster or dwarf galaxy that has now been torn apart and stretched out along its orbit by tidal forces.

[2] Due to new deeper sky surveys, such as the DESI Legacy Imaging Survey, a large number of streams are to be expected to be discovered in the future.

They plan to search about 3100 galaxies, which might yield hundreds of candidates.

In the pasts less sensitive surveys such as SDSS were only able to detect the brightest stellar streams.
