"This new image of NGC 2264, also known as the 'Christmas Tree Cluster,' shows the shape of a cosmic tree with the glow of stellar lights. NGC 2264 is, in fact, a cluster of young stars — with ages between about one and five million years old — in our Milky Way about 2,500 light-years away from Earth. The stars in NGC 2264 are both smaller and larger than the Sun, ranging from some with less than a tenth the mass of the Sun to others containing about seven solar masses.

This new composite image enhances the resemblance to a Christmas tree through choices of color and rotation. The blue and white lights (which blink in the animated version of this image) are young stars that give off X-rays detected by NASA’s Chandra X-ray Observatory. Optical data from the National Science Foundation’s WIYN 0.9-meter telescope on Kitt Peak shows gas in the nebula in green, corresponding to the 'pine needles' of the tree, and infrared data from the Two Micron All Sky Survey shows foreground and background stars in white. This image has been rotated clockwise by about 160 degrees from the astronomer’s standard of North pointing upward, so that it appears like the top of the tree is toward the top of the image.

Young stars, like those in NGC 2264, are volatile and undergo strong flares in X-rays and other types of variations seen in different types of light. The coordinated, blinking variations shown in this animation, however, are artificial, to emphasize the locations of the stars seen in X-rays and highlight the similarity of this object to a Christmas tree. In reality the variations of the stars are not synchronized.

The variations observed by Chandra and other telescopes are caused by several different processes. Some of these are related to activity involving magnetic fields, including flares like those undergone by the Sun — but much more powerful — and hot spots and dark regions on the surfaces of the stars that go in and out of view as the stars rotate. There can also be changes in the thickness of gas obscuring the stars, and changes in the amount of material still falling onto the stars from disks of surrounding gas.

NASA’s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts."

«This week NASA unveiled a new image of NGC 2264, also known as the "Christmas Tree Cluster," (pictured below) which resembles a Christmas tree outlined by the radiance of stellar lights. Positioned roughly 2,500 light-years away from Earth, the cluster comprises stars between one to five million years old and sizes both smaller and larger than our Sun.»

Christmas Tree Cluster

A fascinating open star cluster with associated bright and dark nebulae.

… and the Cone Nebula NGC 2264 Complex in Monoceros Image exposure: 120 MinutesImage Size: 2.11 º x 1.4ºImage date:2024-03-05 The NGC 2264 complex is a huge nebula of hydrogen which forms a tenuous star-forming gas cloud approximately 25 light years across and some 2,300 light years distant. It also contains a dark nebula and an association of over a hundred hot young stars. Most of the…
