Bending Light is cool.

"Einstein predicted that the gravity of a massive object such as a galaxy will bend light like a lens. In some cases, the lensing can image distant objects that lie behind the galaxy. Astronomers have studied such gravitational lenses for decades. Now they are ready to turn them into a powerful tool to test the latest theories of the structure and evolution of the universe."
