DescriptionSites and pages with material about the astronomical applications of the gravitational deflection of light predicted by general relativity: from the multiple and distorted images produced when the light of distant astronomical objects is deflected by the masses of less distant galaxies or other astronomical bodies, astronomers and cosmologists can extract information about the lensing system, the distant source, or even the cosmos as a whole.
