(series of high-velocity clouds associated with the Magellanic Clouds)
The Magellanic Stream is a high-velocity cloud (HVC) or series of HVCs
leading away from the Magellanic clouds.
In our view, it is a line across the celestial sphere extending
an angular distance of 180 degrees.
The clouds consist of gas, but a young stellar cluster has been
identified within them. The initially-discovered clouds tail the
movement of the Magellanic Clouds in their orbit around the
Milky Way, but the stream is now observed to extend forward along
this trajectory as well. They are presumed to have formed from
tidal force on the Magellanic Clouds from the Milky Way,
shaped by hydrodynamic forces within the Milky Way galactic halo.
