Shown Here: Hubble Space Telescope view of the distant quasar RXJ1131-1231. A foreground galaxy smears the image of the background quasar into a bright arc (left) and creates a total of four images — a phenomenon known as gravitational lensing. Such lensed views allowed scientists to come up with a new estimate for how fast the universe is expanding. Read the Full Story | Watch the Video .
