an extremely compact violently variable form of active galaxy
BL Lac object
(bē’ěl’ läk’)
A distant radio galaxy with an intensely bright active galactic nucleus that emits a jet of material directly toward the Earth. BL Lac objects may be a class of blazar, though there is evidence that they are an optical effect caused by gravitational lensing of some other bright object by an intervening galaxy. Also known as BL Lacertae objects.
