The 30 Doradus region in the Large Magellanic Cloud (LMC) is the largest known star forming region in the local group of galaxies. R136 in the center of NGC 2070 (Tarantula Nebula) is an extremely dense cluster of stars (121 stars within a diameter of 15 Lj) that produces about half of the ionization energy for 30 Doradus. The cluster has a total mass of roughly 450'000 solar masses and containes some of the largest known stars (the largest with about 300 solar masses).
