This collection of images represents the thousands of observations that are permanently stored and accessible to the world in the Chandra Data Archive (CDA). This sample showcases the wide range of objects that Chandra has observed during its over 14-year mission, including the remains of exploded stars, cosmic nurseries where stars are being born, and galaxies both similar to our Milky Way and those that are much different. In each of these images, the Chandra data are blue or purple and have been combined with those from other wavelengths.
