X-ray, Infrared & Optical Images of NGC 1333
NGC 1333 is a cluster that contains many stars that are less than two million years old, which is very young in astronomical terms. These images show the Chandra X-ray data of NGC 1333 as well as infrared data from Spitzer and visible light data from ground-based telescopes. The Chandra data reveal 95 young stars glowing in X-ray light, 41 of which had not been identified previously. In addition, X-ray observations can reveal information about the physical properties and behaviors of these very young stars.
