Gravitational Lensing

Gravitational lensing is an astrophysical technique which uses the observed path of light  from distant objects to both infer characteristics of foreground mass distributions, and to image background sources at much higher resolution than is possible with normal telescopes.  Researchers at the University of Melbourne have a long history of developing innovative applications for gravitational lensing.
