Telescope: Stellarvue SVX102T-R Raptor 102mm Carbon Fiber Triplet & SFFR-74-102T Focal Reducer Flattener | Designation: A two panel mosaic of The Rosette Nebula (also known as Caldwell 49) an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The complex has the following New General Catalogue (NGC) designations: NGC 2237 – Part of the nebulous region (Also used to denote whole nebula) NGC 2238 – Part of the nebulous region NGC 2239 – Part of the nebulous region NGC 2244 – The open cluster within the nebula The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses. A diffuse X-ray glow is also seen between the stars in the bubble, which has been attributed to a super-hot plasma with temperatures ranging from 1 to 10 million K. This is significantly hotter than the 10,000 K plasmas seen in HII regions, and is likely attributed to the shock-heated winds from the massive O-type stars. On April 16, 2019 the Oklahoma Legislature passed HB1292 making the Rosette Nebula as the official state astronomical object. Oklahoma Governor Kevin Stitt signed it into law April 22, 2019. (WIKI) |
