IceCube is providing a unique view into the universe

~ Greg Moore

IceCube is a neutrino detector at the South Pole that uses 5,160 light sensors to detect the tiny light flashes that result when neutrinos interact with ice. Neutrinos are hard-to-detect subatomic particles with nearly no mass that are created by the sun, radioactive decay, cosmic rays, and violent events such as exploding stars. The detector—sometimes referred to as a telescope …
