Super-luminal motion is found in radio galaxies. It's apparently faster than speed of light!
So what are radio galaxies? These are just those active galaxies which are highly illuminated at radio frequencies. Their illumination is of the order of 10^39 W, (at radio frequencies) which is approximately 10,000,000,000,000 times the illumination of our Sun!
