The growing field of neutrino astronomy searches for the origins of high-energy (> 1 TeV), astrophysical neutrinos using cubic-kilometer-scale detector arrays. One such array, the IceCube neutrino observatory, uses the glacial ice at the South Pole to detect Cherenkov light from neutrino interaction products. Neutrinos can provide unique information about the cosmic ray acceleration processes that occur in the most extreme environments of the universe. In 2013, IceCube measured the astrophysical neutrino flux for the first time. Since then, IceCube has searched for the specific neutrino sources and found evidence for neutrino emission from the blazar TXS 0506+056, the X-ray bright Seyfert galaxy NGC 1068, and the Galactic plane. Most recently, the field was energized by KM3NeT's detection of the highest-energy neutrino ever recorded–likely exceeding 100 PeV–using their partially constructed detector in the Mediterranean Sea. This talk will provide an overview of the recent progress in neutrino astrophysics and prospects for future discoveries.
