==**Explanation:** Would the [|Rosette Nebula] by any other [|name] //look// as [|sweet]? The bland [|New General Catalog] designation of [|NGC 2237] doesn't appear to diminish the appearance of [|this] flowery [|emission nebula]. Inside the nebula lies an [|open cluster] of bright young stars designated [|NGC 2244]. These stars [|formed about four million years ago] from the nebular material and their [|stellar winds] are clearing a hole in the nebula's center, insulated by a layer of [|dust] and hot gas. [|Ultraviolet light] from the hot cluster stars causes the surrounding nebula to [|glow]. The [|Rosette Nebula] spans about 100 [|light-years] across, lies [|about 5000 light-years away], and can be seen with a small telescope towards the [|constellation] of the Unicorn ([|Monoceros]).==
