The Magellanic Stream is a vast river of hydrogen gas flowing into our galaxy from the dwarf satellite galaxies known as the Magellanic Clouds. Astronomers had thought that it contained about a billion solar masses’ worth of gas. Now, however, observations by the Hubble Space Telescope suggest that the actual number could be as high as 14 billion. That’s good news for our Milky Way galaxy, because the Magellanic Stream (shown as a red streak in sky map above) will be its main source of building material for future stars.
