Huge gas cloud will hit Milky Way. A giant cloud of hydrogen gas is racing towards a collision with the Milky Way, astronomers have announced.

Huge gas cloud will hit Milky Way

Dubbed "Smith's Cloud", it may set off spectacular fireworks when it smacks into our galaxy in 20-40 million years. It contains enough hydrogen to produce a million stars like our Sun, researchers believe. When it does fully interact with our galaxy, the cloud could indeed set off a new burst of star formation in the Milky Way. Details of the work, by a team at the US National Radio Astronomy Observatory and the University of Wisconsin-Whitewater, were unveiled at the 211th meeting of the American Astronomical Society in Austin, Texas.
