Large Magellanic Cloud
The Large Magellanic Cloud (LMC) is a dwarf satellite galaxy of the Milky Way, located about 160,000–200,000 light‑years away in the southern constellations Dorado and Mensa. Roughly 10,000 light‑years across, it is rich in star-forming regions—such as the Tarantula Nebula—and contains billions of stars.

The Large Cloud of Magellan
10/05/2006
Portuguese navigator Fernando de Magellan and his crew had plenty of time to study the southern sky during the first circumnavigation of planet Earth. As a result, two fuzzy cloud-like objects easily visible for southern hemisphere skygazers are known as the Clouds of Magellan. Of course, these star clouds are now understood to be dwarf irregular galaxies, satellites of our larger spiral Milky Way galaxy. The Large Magellanic Cloud (LMC) pictured above is only about 180,000 light-years distant in the constellation Dorado. Spanning about 15,000 light-years or so, it is the most massive of the Milky Way's satellite galaxies and is the site of the closest supernova in modern times. The prominent red knot on the left is 30 Doradus, or the Tarantula Nebula, a giant star-forming region in the Large Magellanic Cloud.
