Researchers discover one of the brightest galaxies ever seen
Scientists at the Instituto de Astrofisica de Canarias, a research institute in the Canary Islands, just discovered one of the brightest galaxies we've ever come across. It's around a thousand times brighter than our galaxy, has a very high rate of star formation and is 10 thousand million light years away.
Rare galactic alignment produces beautiful light 'ring'
First predicted by Einstein's theory of General Relativity, an "Einstein Ring" is a rarely observed, but incredibly interesting astronomical phenomenon that occurs when two distant galaxies are perfectly aligned, millions of light years apart. The light from the more distant "source" galaxy becomes bent and distorted as it passes through the gravitational field caused by the mass of the less-distant "lens" galaxy, resulting in a circle of light around the glow of the lens.
