The Tarantula Nebula is more than 1,000 light-years across - a giant emission nebula within our neighboring galaxy the Large Magellanic Cloud. Inside this cosmic arachnid lies a central young cluster of massivestars, cataloged as R136, whose intense radiation and strong winds have helped energize the nebular glow and shape the spidery filaments.
