False colour X-ray image of quasar 3C 273 and its jet, recorded by the Eistein Observatory satellite. Earth at a distance of 2100 million light years. The quasar is a powerful emitter of radiation at all wavelengths. It emits over a million times more X-rays than our Milky Way galaxy. In this image, X-ray brightness is coded according to intensity, with the most intense areas in white and red. The red spot at lower right is the jet . The spokes around the quasar are due to the imaging system.
