Rosette Nebula Nebulae in the Milky Way

Rosette Nebula Nebulae in the Milky Way

Could the Rosette Nebula have any other name that looks so sweet? The bland designation by the New General Catalog of NGC 2237 does not appear to diminish the appearance of this flowering emission nebula.

Inside the nebula lies an open cluster of bright young stars designated as NGC 2244. These stars, formed four million years ago from nebular material and stellar winds, are clearly visible in a hole in the center of the nebula, isolated by a layer of dust and hot gas. The ultraviolet light that comes from the hot cluster causes the brightness of the nebula around it.

The Rosette Nebula expands 100 light years and is around 5000 light years from us, it can be seen through small telescopes to the constellation Monoceros.
