| Notes | A large, faint emission nebula and bright galactic association of stars known as The Christmas Tree Cluster form object NGC 2264, which itself contains a unique feature known as the Cone Nebula. The Cone Nebula’s shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by nearby star S Monocerotos, the brightest star of NGC 2264. The faint nebula is approximately seven light-years long and is 2,700 light-years away from Earth. It was discovered by the famed English astronomer William Herschel on December 26, 1785. |
