Recently captured images from two of NASA’s space telescopes offer a festive view of the cosmos, demonstrating how the light from young stars can transform space into a holiday spectacle.
One set of observations from the Chandra X-ray Observatory reveals groupings of stars arranged in a pattern resembling a Christmas tree, adorned with radiant lights. In a separate set of images taken by the Hubble Space Telescope, a celestial arrangement resembling a scintillating snow globe is on display, adding to the cosmic holiday cheer.
NGC 2264, which is about 2,500 light-years from Earth, is also called the “Christmas Tree Cluster,” where a group of young stars surrounded by the gaseous cloud of a nebula call to mind a cosmic evergreen decorated with twinkling lights. Recently captured images
The stars featured in these festive cosmic images are relatively young, ranging from 1 million to 5 million years old, and exhibit a variety of sizes—some smaller and others larger than our sun. The composite image, adjusted by 160 degrees to position the top of the tree upright, combines different wavelengths of light detected by the Chandra X-ray Observatory along with data from ground-based surveys.
In an animated version of the image, the blinking blue and white lights signify the X-ray emissions from the young stars, as captured by Chandra. Simultaneously, the green glow of the gas cloud resembling a Christmas tree is depicted in optical light, observed through the National Science Foundation’s WIYN 0.9-meter telescope on Kitt Peak in the Arizona-Sonoran Desert.
The white stars scattered throughout the image were unveiled through observations in infrared light, courtesy of the Two Micron All Sky Survey, which operated from 1997 to 2001. The study of young stars, exemplified by those within the Christmas Tree Cluster, provides valuable insights into their dynamic nature. These youthful stars have the potential to release powerful flares exceeding the intensity of those produced by our sun, and astronomers continue to explore and understand this phenomenon.
