Near Perfect "Einstein Ring" Discovered

Near Perfect "Einstein Ring" Discovered: "Gravitational lensing happens when the gravity of a relatively close galaxy acts as a telescope lens to focus the light from a more distant galaxy. It allows astronomers to see distant objects they could never have a hope of observing with current instruments, essentially looking back to moments after the Big Bang (cosmically speaking). The galaxies are never perfectly lined up, though, and the 'natural telescope' is a bit blurry. But now astronomer Remi Cabanac has found one of the most complete lenses ever discovered: a near perfect Einstein Ring, magnifying a distant galaxy with incredible clarity."
