Hubble finds double Einstein ring

A very rare phenomenon found with the Hubble Space Telescope may offer insights into dark matter, dark energy, the nature of distant galaxies, and even the curvature of the Universe, according to an international team of astronomers who are reporting at the 211th meeting of the American Astronomical Society in Austin, Texas.

This effect is created when three (four, if you count ours) galaxies line up perfectly behind each other while being great distances apart, the phenomena is an observable proof of Einstein’s general relativity. It’s not often you get to see a picture of space-time being warped by gravity, eh?
