Description
The discovery of TeV-PeV astrophysical neutrinos in 2013 by IceCube precipitated the decade of spectacular progress in which we thrive today. So far, we have found the first extragalactic transient and steady-state sources of high-energy astrophysical neutrinos, plus neutrinos from comparatively nearby, the Galactic Plane. I will review these discoveries, what we have learned about the first neutrino sources, and the larger insight we have garnered from them---and from the non-detection of neutrinos from other candidate sources---about the population of unresolved sources responsible for the bulk of the detected neutrinos. Finally, I will show fascinating prospects for the next decade or two: an enhanced, all-sky potential to discover much dimmer sources of high-energy neutrinos, thanks to a global distributed network of neutrino telescopes, and the discovery of long-sought ultra-high-energy neutrinos, above 100 PeV, which may finally reveal the origin of ultra-high-energy cosmic rays.
