Physicists Snare Neutrinos From the Cosmos

Staff Writer

After 40 years of trying, physicists have detected subatomic particles called neutrinos zinging in at high energies from beyond our solar system. The observation comes from a detector called IceCube, built into 1 cubic kilometer of ice at the South Pole, and some physicists say it marks the birth of neutrino astronomy. However, IceCube sees high-energy neutrinos at such a low rate that it may not be able to map individual sources of them in the sky, the ultimate goal. That may require an even bigger detector.
