Day 23 of the 2012 Hubble Space Telescope Advent Calendar - - Thanks to the presence of a natural "zoom lens" in space, this is a close-up look at one of the brightest distant "magnified" galaxies in the universe known to date. It is one of the most striking examples of gravitational lensing, where the gravitational field of a foreground galaxy bends and amplifies the light of a more distant background galaxy. In this image the light from a distant galaxy, nearly 10 billion light-years away, has been warped into a nearly 90-degree arc of light in the galaxy cluster RCS2 032727-132623. - Via In Focus:
