Also known as 30 Doradus or NGC 2070, the Tarantula Nebula, so called because it resembles a web, is a HII region (red/pink shows hydrogen) about 1,000 light-years in length, located in the Great Magellanic Cloud , a small satellite galaxy of the Milky Way, at an estimated distance of 170,000 light-years from Earth.

Despite the splendor of this image, we are facing an extremely hostile place for life. Here the stars form, evolve, and end their lives rapidly, often violently. The photograph contains stars at different stages of its evolution, some newly formed (about 2 million years old), still hidden in dense, dark gas bubbles, as well as the remnant of giants that ended their cycle in supernova explosions.
