Activity from a supermassive black hole is responsible for the intriguing appearance of this galaxy, 3C305, located about 600 million light years away from Earth. The structures in red and light blue are X-ray and optical images from the Chandra X-ray Observatory and Hubble Space Telescope respectively. The optical data is from oxygen emission only, and therefore the full extent of the galaxy is not seen. Radio data are shown in darker blue and are from the National Science Foundation's Very Large Array in New Mexico, as well as the Multi-Element Radio-Linked Interferometer Network in the United Kingdom.

3C305

An unexpected feature of this multiwavelength image of 3C305 is that the radio emission -- produced by a jet from the central black hole -- does not closely overlap with the X-ray data. The X-ray emission does, however, seem to be associated with the optical emission.
