The Large Cloud of Magellan

Explanation: Magellan and his crew had plenty of time to study the southern sky during their famous voyage around the world. As a result, two fuzzy cloud like objects, nestled among the southern constellations of Doradus and Tucana are now known as the Clouds of Magellan. The Magellanic Clouds are small irregular galaxies , satellites of our larger Milky Way spiral galaxy. The Large Magellanic Cloud (LMC) pictured above is the closest galaxy to our own Milky Way, at a distance of about 180,000 light years. The Magellanic Clouds are joined to the Milky Way by a stream of cold hydrogen gas whose origin is still controversial. An unusual effect called gravitational lensing has recently been detected in a few LMC stars, and there is hope this could tell us important information about the true composition of our universe.
