IceCube reaches 20-year milestone in quest to uncover the makeup of ultra-high-energy cosmic rays
Cosmic rays are charged particles that rain down on Earth from space, with energies that can reach as high as a fast-thrown baseball packed into a single subatomic particle. Although a lot is known about cosmic rays, their origin still remains a century-old mystery. The highest energy particles, called ultra-high-energy…
IceCube’s first hunt for neutrino sources using two types of signals
The origins of cosmic rays—and the astrophysical sources responsible for producing and accelerating them—remain an open question in science. However, high-energy neutrinos, nearly massless subatomic particles, may hold the key to resolving this long-standing mystery. At the South Pole, the IceCube Neutrino Observatory occupies a cubic kilometer of ice in…
Week 26 at the Pole
There’s a lot of snow around at the South Pole for a place that’s classified as a desert. That’s because it is carried in from strong winds that blow across the continent. And the blowing snow accumulates around the station and all the structures located at the Pole, including the…
