Swift Team Finds Bright Burst

Facebook X LinkedIn Email
LEICESTER, England, March 21, 2008 -- Astronomers have found by far the most distant object ever seen by the naked eye -- a gamma ray burst from 7.5 billion light-travel years away. "The object that exploded produced more optical light than anything else we have ever seen," said Paul O'Brien, a senior lecturer of physics and astronomy at Leicester University in Leicester, England, in an e-mail. "It was, at peak, approximately equivalent to a few hundred million billion suns!" O'Brien is one of a large team of scientists around the world who continually monitor gamma-ray bursts, or GRBs, found by the Swift satellite. Swift...Read full article

    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
