NASA's Fermi Makes First Gamma-ray Study of a Gravitational Lens
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.
This accomplishment opens new avenues for research, including a novel way to probe emission regions near supermassive black holes. It may even be possible to find other gravitational lenses with data from the Fermi Gamma-ray Space Telescope.

The trick is to not use https when trying to embed YouTube videos.
Just call me "geck" because "zilla" is like a last name.
