How to find neutrinos in underground ice
For the first time in more than 25 years, scientists have detected neutrinos from outside our solar system. The neutrinos were caught in the act of zooming through a giant block of ice a mile below the South Pole. The IceCube Neutrino Observatory has detected 28 of the subatomic particles since it opened in 2010, according to a new report in the journal Science.

The IceCube Neutrino Observatory at the Amundsen-Scott South Pole station in Antarctica is the world's largest neutrino detector. Its computers collect raw data on neutrino activity from sensors in the ice that look for light emitted when neutrinos strike.
