Star cluster NGC 2264, also called the "Christmas tree cluster," is an array of young stars that are between one and five million years old. We know what you're thinking: young?! For a little comparison, the Sun is a middle-aged star about 5 billion years old about 1,000 times older than the stars in this cluster.
This image combines data from Chandra (red, green, and blue) with optical data (green and white) captured by astrophotographer Michael Clow with his telescope in Arizona in November 2024.
