NGC 2244 (also known as Caldwell 50 or the Satellite Cluster) is an open star cluster in the Rosette Nebula, located in the constellation Monoceros. ngc 2244 (also known as Caldwell 50 or the Satellite Cluster) is an open star cluster in the Rosette Nebula, located in the constellation Monoceros. In close proximity to the “southeast” of the cluster is a field of K-class stars (The Orange Giant Fields); they do not form part of the cluster, but within a radius of 1000 LY their density is relatively high. NGC 2244 (also known as Caldwell 50 or the Satellite Cluster) is an open star cluster in the Rosette Nebula, located in the constellation Monoceros.
Wikipedia In the heart of the Rosette Nebula lies a bright open star cluster that illuminates the nebula. Wikipedia At the heart of the Rosette Nebula is a bright open star cluster that illuminates the nebula. The image shown here, taken in January using multiple exposures and very specific colours of sulphur (shaded red), hydrogen (green) and oxygen (blue), captures the central region in enormous detail.
Who discovered NGC 2244?
Astronomers divide the two into NGC 2174 and NGC 2175, but the object is most commonly seen under the designation NGC 2175.Spectrum synthesis using a line synthesis code that takes into account the effects of the strong magnetic field shows that He is underrepresented by about 1.5 dex and C, O and Mg by about 0.1-0.4 dex, while Si, Mn and Fe are overrepresented by about 1 dex and Cr and Ti are overrepresented by nearly 2 dex. Astronomers subdivide them into NGC 2174 and NGC 2175, respectively, but most often the object is referred to as NGC 2175. Spectrum synthesis using a line synthesis code that takes into account the effects of the strong magnetic field shows that He is underabundant by about 1.5 dex and C, O and Mg by about 0.1-0.4 dex, while Si, Mn and Fe are overabundant by about 1 dex and Cr and Ti are overabundant by almost 2 dex. The centre of the Rosette Nebula measures about 50 light-years in diameter, lies about 5,200 light-years away, and is visible with binoculars in the direction of the constellation Unicorn (Monoceros). The nebula is a large cloud of gas and dust located near a large molecular cloud and is closely associated with the open star cluster NGC 2244, whose stars were formed from the nebula’s matter over the last five million years.
What is NGC 3603 classified as?
NGC 3603 is a nebula in the Carina-Sagittarius arm of the Milky Way, about 20 000 light years from the Solar System. In astronomy it is common to use the Roman numeral I for neutral atoms, II for singly ionised H II is H in other sciences III for doubly ionised, e.g. NGC 3603-A1 (HD 97950A is a binary star system in the centre of the star cluster HD 97950 in the star forming region NGC 3603, about 25 000 light years from Earth. It was discovered by Sir John Herschel in 1834 and is the largest nebula visible in visible light in the Milky Way.
How big is the Rosette Nebula?
The Rosette Ne bula is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The centre of the Rosette Nebula is about 1.8 degrees below the galactic plane whose glow can be seen in the upper left (northeast) corner of this image. The young stars at the centre of the nebula are bound together by gravity; they form an open cluster of stars composed of the nebula’s material. To observe the Rosette Nebula visually, you need to point your telescope at the constellation Monoceros and find an extremely dark, moonless sky.
Who gave the Rosette Nebula its name?
The giant column of gas and dust was named after its conical shape, which results from a dark nebula absorbing light from an emission nebula behind it. This open star cluster was discovered by John Flamsteed in 1690, but the discovery of the Rosette Nebula required much more effort. A survey of the nebula with the Chandra X-ray Observatory revealed the presence of numerous newborn stars in the Optical Rosette Nebula, distributed in a dense molecular cloud. This large cloud of gas and dust is about 5,000 light years from Earth, although other estimates of the Rosetta Nebula’s distance are as little as 1,500 light years.
