How Gravitational Lensing Works (image) University of Arizona Caption A galaxy along the line of sight between Earth and another, much more distant galaxy, bends the light from the distant galaxy under its gravitational field, providing astronomers with a magnified and distorted image of the distant galaxy. An analysis of the distortion has revealed that some of the distant star-forming galaxies are as bright as 40 trillion suns, and have been magnified by the gravitational lens by up to 22 times.
