Video Honk if you love neutrinos
Actually, don’t honk — it would be rude — but enjoy the UW–Madison IceCube Neutrino Observatory display at Madison’s Holiday Fantasy in Lights in Olin Park. IceCube, located at the South Pole, surveys a billion tons of Antarctic ice for signs of the ghostly subatomic particles known as neutrinos. At left in the display is a representation of a supermassive exploding star — a hypernova — one source of neutrinos in the universe. In the center, a depiction of the array of optical sensors buried deep beneath the South Pole that capture telltale flashes of blue light whenever a neutrino strikes an ice particle. IceCube is made up of over 5,000 light sensors strung on long cables. At right is an outline of the IceCube Neutrino Observatory.
