  The IceCube Neutrino Observatory is the world's largest neutrino detector,
instrumenting a cubic kilometer of ice at the geographic South Pole. The
detector probes neutrino energies from GeV to PeV, and collects high statistics
neutrino samples by virtue of its extremely large volume. IceCube was designed
to detect high-energy neutrinos from potential cosmic ray acceleration sites
such as active galactic nuclei, gamma ray bursts and supernova remnants.
IceCube announced the detection of a diffuse flux of astrophysical neutrinos in
2013, including the highest energy neutrinos ever detected. IceCube has since
developed a robust system of realtime alerts generated by astrophysical
neutrino candidates that trigger rapid follow-up observations by other
telescopes and detectors. In September 2017, IceCube observed a neutrino in
coincidence with a flaring blazar, signaling the era of neutrino astronomy and
widening the field of multi-messenger astronomy. The IceCube science program
extends beyond multi-messenger astronomy to include the fundamental physics of
neutrino oscillations and neutrino interactions with matter, cosmic ray
physics, and searches for particles and forces beyond the Standard Model. These
proceedings will cover the latest neutrino physics and astrophysics results
from IceCube and future prospects for the detector.
