OJ287 kiloparsec-scale jet
Above: BL Lac object OJ287, at a redshift of 0.306 (distance of 5.15 billion light-years), so that 1" corresponds to 15,000 light-years
False color: X-ray image from the Chandra X-ray Observatory;
contours: 1.4 GHz radio image from the Very Large Array. Click here to view a similar jet in a quasar.
