... It is an emission nebula surrounding a cluster of hot, young stars called the 30 Doradus super cluster. This cluster may contain the most massive stars known (about 50 times the mass of the Sun). Such massive stars put out more than 100 times as much energy as our Sun. The bright "star" (lower right) is actually Supernova 1987a and is a harbinger of things to come for the stars within the Tarantula. ... Publications with keywords: supernova .
