Just in time for the holidays, a new composite image of the Christmas Tree Cluster (NGC 2264) has been released. This image is a group effort: the blue and white stars in the cluster giving off X-rays are seen by Chandra, while the faint green nebula was imaged by the WIYN 0.9-meter telescope on Kitt Peak.

Astrophoto: Pulp Fiction by César Cantú

Astrophotographer César Cantú from the Chilidog Observatory in Monterrey, Mexico calls this image “Pulp Fiction” for its violent areas of hot, deadly gases being expelled by the young stars, solar windstorms, huge accumulations of cosmic dust. But the two features show here are actually are named after things much more peaceful in nature: The Cone Nebula and the Christmas Tree Cluster. This open cluster of stars was discovered by William Herschel in 1785 and is cataloged as NGC 2264 and lies at a distance of 2,600 light years from our solar system.

“This is an H II region located in the constellation Monoceros,” César says, “a region with much stardust. The picture shows also the Hubble Variable Nebula, like a little flash at the top right. This is a vast field reached with the telescope and focal reducer FSQ106, which gives a focal length of 385mm with great resolution. The camera used was the FLI8300, with 4:30 hours of exposure.”
