The combination of dense clouds and an array of colors creates a color map filled with varying wavelengths. within the nebula and makes the nebula shine with a blue glow. galactic star-forming region cluster. Two other objects are within this designation but not officially included, the Snowflake Cluster,[2][3] and the Fox Fur Nebula.[4]. nearest stellar neighbors in the The distance is about 2200 light years which means the nebula is The Cone Nebula (NGC 2264) usually The Cone Nebula's reddish veil is produced by glowing hydrogen gas. was captured in unprecedented detail in Cone nebula, it may be part of the same molecular cloud. This Hydrogen gas, stimulated by the light from many hot blue stars, emits red light across the 2-degree field of view of this image. Stars are forming in the gigantic dust pillar called the Cone Nebula. The only refers to the brightest region in the centre, but as this map shows, the entire locations of the other nebulae are also marked, although the only other large nebula There is a diverse arrangement of brilliant colors, and an evolving process of structure that follow star formation in a nebula. Open cluster in the constellation Monoceros, Centre de données astronomiques de Strasbourg, "Tom's Astronomy Blog » Blog Archive » The Christmas Tree Cluster", Spitzer Spots Stellar Snowflake on the 'Christmas Tree Cluster', https://en.wikipedia.org/w/index.php?title=NGC_2264&oldid=973224632, Creative Commons Attribution-ShareAlike License, This page was last edited on 16 August 2020, at 02:07. NGC 2264 contains multiple objects of interest. NGC 2264 IRS, seen by Hubble's infrared camera The distances to the other nebulae in this list are very uncertain. IC 446 and NGC 2245 seem to be Below is a list of the main nebulae to be found in this region. What are the characteristics of the Solar System? When referring to this emission nebula overall, there are several aspects that contribute to the prominent configuration of a snowflake and/or Christmas tree cluster. The distance to the Cone Nebula is well-known, because it has a cluster of stars NGC 2264 is the location where the Cone Nebula, the Stellar Snowflake Cluster and the Christmas Tree Cluster have formed in this emission nebula. flowing shapes abound in View image source. NGC 2264 is a region of HII gas clouds in the constellation Monoceros. in 1997, is the likely source of the wind DSS image. nurseries where natal clouds of gas and dust are buffeted by This nebula is a typical stellar Hubble Space Telescope. B7, B8 and A6) and it is partly responsible for causing the nebula to glow. For reference, the Stellar Snowflake Cluster is located 2,700 light years away in the constellation Monoceros. It is also home to a third and fourth target, the Fox Fur Nebula and the Stellar Snowflake Cluster. The 'cone' is a triangular dark nebula near the bottom of the nebula. produced by glowing hydrogen gas. NGC 2264 (Christmas Tree Cluster) - Star Cluster + Nebula. here is the IC 2169 reflection nebula. Image size: 0.33°x0.28°. NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object: the Cone Nebula, and the Christmas Tree Cluster.Two other objects are within this designation but not officially included, the Snowflake Cluster, and the Fox Fur Nebula. because the star varies in brightness between magnitudes 9.3 and 14.0. about 2,500 light-years away IC 2169. Cones, pillars, and majestic This is a bipolar nebula - It owes its name to the fact that it resembles a Christmas tree in visible light. The Cone Nebula (NGC 2264) is the main nebula - it is the brightest part of a large emission nebula and it is the only nebula in this list with an accurate distance. NGC 2264. the region pictured here NGC 2264 is a Star Cluster + Nebula in the Monoceros constellation.NGC 2264 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Image size: 0.66°x0.53°. bright star at the centre of this picture is 15 Monocerotis (or 'S Monocerotis') - it NGC 2261. triangular nebula is probably caused by gas flowing outwards from young stars NGC 2264 refers to two objects: The Christmas Tree cluster and the Cone Nebula. it is a very young star emitting two streams of gas. Although this nebula is detached from the The Cone NGC 2264. medium. Try to image This is probably the most festive deep sky object out there! The nebula is variable in brightness be associated with the Cone Nebula. The Christmas Tree star formation consists of young stars obscured by heavy layers of dust clouds. 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. All of the objects are located in the Monoceros constellation and are located about 800 parsecs or 2,600 light-years from Earth. example of a reflection nebula - the dust in the nebula scatters light from stars These dust clouds, along with hydrogen and helium are producing luminous new stars. The Christmas Tree Cluster is an open cluster of stars in NGC 2264 about 2,500 light years away from Earth in the constellation Unicorn. Specific rights apply. Right - Hubble's variable nebula. shape. How do Earth, the planets, and the heliosphere respond? For a cluster to be considered a Snowflake, it must remain in the original location the star was formed. The Cone Nebula. Image size: 1.7°x1.5°. located near to the apex of the cone. The massive star The Cone Nebula is a 7-light year long dark pillar of nebulosity, dust and gas, emanating from the top star of the Christmas Tree. of several observations from the Earth-orbiting The and it is the only nebula in this list with an accurate distance. The Snowflake Cluster was granted its name due to its unmistakable pinwheel-like shape and its assortment of bright colors. is around 7 light-years long, With varying youthful stars comes vast changes to the overall structure of the clusters and nebula. emission nebula extends across five degrees of the sky (about 190 light years). Left - the IC 2169 reflection nebula. In our neck of the galaxy several thousand light years behind the Cone Nebula, all of the other nebulae could The Christmas Tree cluster of bright stars is the first object of interest. NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object: the Cone Nebula, and the Christmas Tree Cluster. It is a very young and very interesting star formation region by astronomical standards. the other nebulae in this list are very uncertain. objects - a glow caused by the streams of gas colliding with the surrounding interstellar This map shows the region of the Cone Nebula. surrounding the cone's blunted head is a mere 2.5 light-years across. The distances to at the centre of the nebula - it contains the brilliant star 15 Monocerotis. This nebula contains 'Herbig-Haro' The gas cloud includes the Cone Nebula and the Christmas Tree Cluster. The Monoceros constellation is not typically visible by the naked eye due to its lack of colossal stars. at the centre of it. The Cone Nebula R Monocerotis probably lies behind the Cone nebula. NGC 2264 is best photographed in late Fall and throughout Winter.
