NASA's Fermi makes first gamma-ray study of a gravitational lens
"Jan. 6, 2014 An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source."
rest at link (beyond me, but know there are geekier than I here)
