The Tarantula Nebula (also known as NGC 2070 or 30 Doradus) is the largest and most active star-forming region in the Local Group, located in the Large Magellanic Cloud about 160,000–170,000 light‑years away. Spanning roughly 600 light‑years, it hosts massive young star clusters like R136, contains some of the most massive stars known (up to ~200 M☉), and is shaped by intense radiation, stellar winds, and supernovae.

In the heart of monstrous Tarantula Nebula lies one of the most unusual star clusters. Known as NGC 2070 or R136, it is home to a great number of hot young stars. The energetic light from these stars continually ionizes nebula gas, while their energetic particle wind blows bubbles and defines intricate filaments. The new Spitzer Space Telescope took the above representative-color infrared image of this great LMC cluster. The image details the cluster's tumultuous center in gas, dust and young stars. The 30 Doradus nebula is one of the largest star-formation regions known, and has been creating unusually strong episodes of star formation every few million years. In the heart of this heart is a central knot of stars that is so dense it was once thought to be a single star.
