This is Cone Nebula (NGC 2264), located in the constellation of Monoceros, the Unicorn! The approximate distance from Earth is 2,700 light years and it is located in the Orion Arm of the milky Way surrounding the NGC 2264 star cluster. It is a triagular dark nebula near the bottom of the nebula. The bright star at the center of this image is 15 Monocerotis (or ’S Monocerotis). it is a quadruple star system consisting of four brilliant blue-white stars (classes O7, B7, B8 and A6) and it is partly responsible for causing the nebula to glow. It is the brightest part of a large emision nebula in the list with accurate sistance.It is a cousin of the M16 pillars. They are common in large regions of star birth. Both are incubators for developing stars.
The Cone Nebula has an apparent length of 10 arcminutes, corresponding to a spatial extension of about 7 light years. It is faint when observed visually, however it is really interesting to be photographed.
