• A ghostly particle detected in Antarctica has led astronomers to a super-massive spinning black hole called a 'blazar'

    The origin of the universe's most powerful cosmic rays , or high-speed particles, has been difficult to determine for decades.
    Astronomers recently used ghostly particles called neutrinos to verify the source of high-energy cosmic rays.
    IceCube , a huge detector embedded in the ice of Antarctica, led to the discovery.
    Enormous, rapidly spinning black holes called blazars appear to emit cosmic rays.
    Astronomers say they've more or less confirmed a key source of cosmic rays - some of the highest-energy yet most enigmatic radiation in the universe - with the detection of a single "ghostly...
