Object Information:
The Cone Nebula ,
Object Type - Dark nebula highlighted by emission nebula,
Constellation - Monoceros,
Distance - 2,500 light years,
Size - Approximately 7 light years long. The tip is estimated to be 2.5
light years across.
Description: The Cone Nebula is a dark nebula located in the constellation of Monoceros, the Unicorn. The Cone Nebula is visible because it lies in front of the faint emission nebula NGC 2264 that makes up the background of this image. It is believed that the tip of the Cone Nebula is an area of active star formation and that the tip is slowly being eroded by the radiation pressure from the bright stars nearby.
