Fimbulthul stream is shown in blue. The ω Cen cluster is just below it.

Fimbulthul is a tidal stellar stream torn off from Omega Centauri, the largest globular cluster of our Milky Way galaxy. The stream contains 309 known stars stretching over 18° in the constellations of Hydra and Centaurus, matching the same age as the globular cluster. Omega Centauri is thought to be the nucleus of a dwarf galaxy that merged with the Milky Way.[1]

The stream was discovered in the Gaia DR2 star database that determined the direction, distances and motion of over one billion stars.[2]

The name Fimbulthul is a river in Norse mythology.
