The Large and Small Magellanic Clouds are dwarf galaxies and satellites of the Milky Way. The Magellanic Bridge is a “fog” of hydrogen gas connecting the two small galaxies, while the Magellanic Stream streams behind them and nearly encircles the Milky Way. Though the galaxies were once thought to be on a closed elliptical orbit (red) around the Milky Way, astronomers recently discovered they are on a parabolic orbit (blue) bringing them close to our galaxy for perhaps the first time.
