The Cone nebula is part of an enormous cloud of hydrogen and tiny solid particles assocaited with the loose open cluster, NGC 2264 in the equatorial constellation of Monoceros. More of this region is seen in image AAT 14. Within and around this cloud are many recently formed stars, some completely hidden within the dense interstellar matter. They can be detected by special infra-red techniques which are able to penetrate the obscuration. The largest of the dust clouds is the curious straight-sided feature which gives this object its name.
