Discovery of a gravitational lens

A recently discovered, close pair of quasars were surprisingly similar in their characteristics. After rejecting other hypotheses, astronomers suggested that the pair is not a pair at all but two images of a single quasar formed by a gravitational lens, an elliptical galaxy halfway between the quasar and our galaxy. Improved calculations of the effects of an extended mass brought agreement between theory and experimental results. 11 figures. (RWR)
