PASADENA, Calif., Oct. 22 (UPI) -- A pattern of light twisted during a journey of billions of years from the very early universe, has been detected for the first time, astronomers say.
During its long travel to Earth, the ancient light was distorted by the pull of matter, leading to a twisted light pattern called B-modes that astronomers have been able to detect using the National Science Foundation's South Pole Telescope and the Herschel space observatory, NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Tuesday.
