The Cone Nebula from Hubble

Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264. The Cone was captured in unprecedented detail in this close-up composite of several observations from the Earth-orbiting Hubble Space Telescope. While the Cone Nebula, about 2,500 light-years away in Monoceros, is around 7 light-years long, the region pictured here surrounding the cone’s blunted head is a mere 2.5 light-years across. In our neck of the galaxy that distance is just over half way from the Sun to its nearest stellar neighbor, the Alpha Centauri star system. The massive star NGC 2264 IRS, seen by Hubble’s infrared camera in 1997, is the likely source of the wind sculpting the Cone Nebula and lies off the top of the image. The Cone Nebula’s reddish veil is produced by glowing hydrogen gas.

NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object:

  • the Cone Nebula,
  • the Christmas Tree Cluster,

Two other objects are within this designation but not officially included:

  • Snowflake Cluster,
  • and the Fox Fur Nebula.

All of the objects are located in the Monoceros constellation and are located about 800 parsecs or 2600 light-years from Earth.

NGC 2264 is sometimes referred to as the Christmas Tree Cluster and the Cone Nebula.

Star forming region NGC 2264: The Cone Nebula and the Christmas Tree Cluster

The Cone Nebula is an H II region in the constellation of Monoceros. It was discovered by William Herschel on December 26, 1785, at which time he designated it H V.27. The nebula is located about 830 parsecs or 2,700 light-years away from Earth. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. The designation of NGC 2264 in the New General Catalogue refers to both objects and not the nebula alone. The diffuse Cone Nebula, so named because of its apparent shape, lies in the southern part of NGC 2264, the northern part being the magnitude-3.9 Christmas Tree Cluster. It is in the northern part of Monoceros, just north of the midpoint of a line from Procyon to Betelgeuse.
