NGC 2237-46 - Rosette Nebula

 

NGC 2237-46

 

NGC 2237-46 is a large area of star formation, clustering, and gas, called the Rosette Nebula. NGC 2244 is the designation of the galactic star cluster at the image's center, where the nebula already has condensed into stars and has thus been "hollowed out". It is surrounded by the red glow of excited hydrogen. This is one of many sites in the Milky Way where "Bok Globules" can be found. These are small, dark, and usually spherical condensations of matter which contain young protostars. The Rosette Nebula and its attendant star cluster lie at a distance of about 6.000 light years and the nebula has a true diameter of about 160 light years, one of the largest galactic nebulae known.
