The Cone Nebula (NGC 2264) is the brightest part of a large emission nebula. The entire emission nebula extends across five degrees of the sky (about 190 light years). The region is ignited by a quadruple star system consisting of four young brilliant blue-white stars (classes O7, B7, B8 and A6). The main body of this hydrogen emission nebula includes regions known as the Christmas tree and Fox Fur nebula. Click here to see a cropped image identifying these regions.
