It may sound abstruse, an “Einstein Ring”…

…but it proves yet again the validity of Einstein’s theories:

Near Perfect “Einstein Ring” Discovered

Summary – (Apr 29, 2005) 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.
