Deep under the ice of the South Pole, an observatory made of thousands of threaded sensors is hunting for ghostly particles called neutrinos, which are forged by some of the most energetic processes in the universe.

Since it first began operations a decade ago, the IceCube Neutrino Observatory has captured dozens of neutrinos created in explosive events such as supernovae or radiant eruptions driven by supermassive black holes. As the biggest neutrino detector in the world, IceCube has opened a new window into the high-energy universe and the bombastic events that occur in it.
