The Cone Nebula (NGC2264) is an active region of starbirth, where new stars form inside a cloud of dust and gas. The hot newborn stars shower the cloud with intense radiation, illuminating its interior while simultaneously eroding it. The Cone is about seven light years long, and the head is about 2½ light years across.
To the north (right) of the Cone lies a vast expanse of glowing gas and stars known as the Christmas Tree Cluster, only part of which is shown here. This image was exposed through a hydrogen-alpha filter emphasize the nebula's details.
