Caption: 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). 3C 321 is 1. 25 billion light years from 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.
