Coronet Cluster Keychain

This composite image shows the Coronet in X-rays from Chandra (purple) and infrared emission from Spitzer (orange, green, and cyan). The Spitzer image shows young stars plus diffuse emission from dust. In the Chandra data only, many of these young stars appear as blue objects, revealing their output of high-energy X-rays and the amount of obscuring dust and gas in the region. | "Smithsonian" and the Smithsonian logo are registered trademarks owned by Smithsonian Institution.
