article_snippet.sent: Gravitational lensing occurs when a massive galaxy or cluster of galaxies bends the light emitted from a more distant galaxy, forming a highly magnified, though much distorted image.
article_snippet.sent: Einstein's theory predicts that the gravitational effects of the nearer galaxy will bend the light of the more distant one.
article_snippet.sent: Gravitational lensing is used in astronomy to study the very distant, very early Universe because it gives even our best telescopes an impressive boost in power,' said Alma Deputy Program Scientist Catherine Vlahakis. '
article_snippet.sent: This unravelling of the bending of light done by the gravitational lens will allow us to study the actual shape and internal motion of the intervening lensing galaxy much more clearly than has been possible until now.'
