In astronomy, superluminal motion is the apparently faster-than-light motion seen in some radio galaxies, BL Lac objects, quasars, blazars and recently also in some galactic sources called microquasars.Bursts of energy moving out along the relativistic jets emitted from these objects can have a proper motion that appears greater than the speed of light.
