Tarantula Nebula Postcard

Asset ID: 78403060 / Stocktrek / Tarantula Nebula _x000D_ _x000D_ The Tarantula Nebula (also known as 30 Doradus , or NGC 2070 ) is an H II region in the Large Magellanic Cloud (LMC). It was originally thought to be a star , but in 1751 Nicolas Louis de Lacaille recognized its nebular nature. _x000D_ The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 49 kpc (160,000 light years ), this is an extremely luminous non-stellar object. Its luminosity is so great that if it were as close to Earth as the Orion Nebula , the Tarantula Nebula would cast shadows. In fact, it is the most active starburst region known in the Local Group of galaxies . It is also the largest such region in the Local Group with an estimated diameter of 200 pc . The nebula resides on the leading edge of the LMC, where ram pressure , and the compression of the interstellar medium likely resulting from this, is at a maximum. At its core lies the compact star cluster R136 (approximate diameter 35 light years) that produces most of the energy that makes the nebula visible. The estimated mass of the cluster is 450,000 solar masses, suggesting it will likely become a globular cluster in the future. _x000D_ In addition to R136, the Tarantula Nebula also contains an older star cluster —catalogued as Hodge 301 —with an age of 20–25 million years. The most massive stars of this cluster have already exploded in supernovae . _x000D_ The closest supernova observed since the invention of the telescope, Supernova 1987A , occurred in the outskirts of the Tarantula Nebula. _x000D_ _x000D_ This page is not affiliated with, or endorsed by, anyone associated with the topic.
