The University of Delaware is helping to build a huge neutrino telescope called "IceCube" in a cubic kilometer of ice at the South Pole. The telescope will detect elusive particles called neutrinos that can travel millions of miles through space passing right through planets. IceCube will provide new information about some of the most distant and violent events in the cosmos. "Chill out" with our UD team as they build the telescope's surface array of detectors called "IceTop."
