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 center of star-forming region 30 Doradus lies a huge cluster of the largest, hottest, most massive stars known. These stars, known as the star cluster R136, and part of the surrounding nebula are captured here in this gorgeous visible-light image from the Hubble Space Telescope. Gas and dust clouds in 30 Doradus, also known as the Tarantula Nebula, have been sculpted into elongated shapes by powerful winds and ultraviolet radiation from these hot cluster stars. The 30 Doradus Nebula lies within a neighboring galaxy, the Large Magellanic Cloud, located a mere 170,000 light-years away.
