Interacting galaxies 3C 321. Composite image of the two 3C 321 galaxies (pink, lower left) and a radio jet (blue) emerging towards upper right from the larger galaxy (bottom left) and being deflected as it hits the smaller galaxy. This jet of high-energy particles is from a supermassive black hole at the centre of the larger galaxy. The image data is from the Chandra X-ray Observatory (X-ray, purple), the Hubble Space Telescope (visible, orange; ultraviolet, red) and the Very Large Array and MERLIN (radio, blue). Earth, in the constellation Serpens Caput. For the separate images of 3C 321, from a study carried out in 2007, see images R826/124 to R826/130.
