Smith Cloud

(Smith's Cloud, Lockman Cloud)
(high-velocity cloud on collision course with Milky Way)

The Smith Cloud (or Smith's Cloud or Lockman Cloud) is a high-velocity cloud within the galactic halo of the Milky Way that apparently will collide with the Milky Way disk in 30 million years. It shows a comet-like tail.

Its trajectory to collide with the Milky Way disk gives credence to the notion that some star formation arises from such collisions, e.g., that of Gould's Belt.
