A "telescope" buried deep under Antarctic ice has detected the first signals that scientists hope will allow them to identify the source of mysterious particles that bombard Earth from outer space.
For the past ten years scientists have been planning and building an ambitious experiment to explain the mystery of what produces the cosmic rays and elusive particles known as neutrinos, which constantly pepper our planet.
They have buried thousands of sensors more than a mile below the surface of Antarctica's ice cap to record fleeting flashes of blue light that are given off when these high energy particles and rays collide with atoms in the ice.
By recording the pattern of light from the collisions, the sensors can plot the trajectory of the particles and rays, allowing scientists to pinpoint where in the galaxy they came from.
