3C 303 is also a radio galaxy[3] It also contains an extragalactic radio source.[4] A clear defined jet is also seen, showing a polarization variation trend. With a diffuse patch of optical emission located at the intersection of the jet where a radio lobe is connected, the jet is confirmed to target a region of interstellar medium.[5]
