«We typically see apparent speeds in blazar jets that are about five times the speed of light, and that corresponds to a true speed of more than 98 percent of light speed,» Piner said. (public.nrao.edu)
Their measurements showed that features in the blazar jets were moving at apparent speeds more than 25 times greater than that of light. (public.nrao.edu)
«Now, based on independent confirmation by two groups of astronomers, we see these three blazars with apparent speeds greater than 25 times that of light,» Piner added. (public.nrao.edu)
