About this Image

The Large Magellanic Cloud (LMC) is an irregular dwarf galaxy orbiting our Milky Way galaxy, and thus is a member of our Local Group of galaxies.
Near the northeastern edge a complex area of emission nebulae, dominated by the bright Tarantula Nebula (NGC 2020) is situated. To the lower right corner the star density increases approaching the LMC.

This area, also named 30 Doradus is actually an immense star forming region. The region's spidery appearance is responsible for its popular name, the Tarantula Nebula in the southern constellation Dorado. If the Tarantual Nebula were at the distance of the Orion Nebula (1,500 light-years), the nearest stellar nursery to Earth, it would appear to cover about 30 degrees on the sky or 60 full moons. The spindly arms of the Tarantula Nebula surround NGC 2070, a cluster that contains some of the intrinsically brightest, most massive stars known. The colors are very much differing from common emission areas, showing its chaotic structure.
The distance to this area is estimated at 179,000 light years. North is up.
