Neutrinos, tiny ghostlike particles billions of times lighter than atoms, are
unique messengers to the cosmos. They are created under exceptional
circumstances— from the nuclear fusion of the sun to the cores of exploding
stars. Unlike cosmic rays and gamma rays, neutrinos are chargeless and weakly
interacting, and arrive from the far reaches of the universe. Unfortunately, they
are notoriously difficult to detect, and their rare fluxes require enormous
detectors.
In this talk, I will describe the Askaryan Radio Array and IceCube Neutrino
Observatory. Both are detectors at the South Pole designed to find neutrinos by
looking for the Cherenkov light emitted in neutrino interactions with the ice. I
will highlight the exciting first decade of science in neutrino astronomy, and
describe the latest results from the experiments. I will conclude by discussing
prospects and plans for the extension to an even larger next generation
detector, IceCube-Gen2.
