This composite image shows the nearby galaxy NGC 7793 that contains a powerful microquasar in its outskirts.

For over a decade, astronomers have been using the Chandra X-ray Observatory to monitor the supermassive black hole in the center of Andromeda, the Milky Way's sister galaxy.

We begin with a composite image of the nearby starburst galaxy M82 that contains X-rays from Chandra in blue, optical data from Hubble in green and orange, and infrared data from Spitzer in red.

This beautiful image shows N49, which is the aftermath of a supernova explosion in the Large Magellanic Cloud.

This composite image of the galaxy cluster Abell 3376 shows X-ray data from the Chandra X-ray Observatory and the ROSAT telescope along with an optical image from the Digitized Sky Survey and radio emission observed by the Very Large Array.

Data from the Chandra X-ray Observatory and the Spitzer Space Telescope were combined to create this image of the dusty remains of a collapsed star.
