The Magellanic Stream is a filament of neutral hydrogen, spanning roughly 300,000 light-years, that may have been torn out of the Magellanic Clouds by the Milky Way Galaxy some 200 million years ago. It forms an arc in the southern sky about 150° long, stretching from the region between the Magellanic Clouds and passing close to the south galactic pole.
