Radio map of the double quasar (0957+561),taken with the Very Large Array (VLA) radio telescope,New Mexico. These two images of a single distant quasar are the result of the gravitational bending of light from the quasar by an intervening body. Image A is the dark blue source at upper centre,which is emitting radio jets (yellow & blue) on either side. Image B is the dark blue object directly below A; the jets have not been doubly imaged. The faint yellow image just above B coincides with the centre of a large galaxy observed in optical light,which,along with the rich cluster of galaxies it lies in,is believed to be acting as the gravitational lens | |
