This episode covers the discovery (strictly speaking, "strong evidence") for high-energy (astrophysical) neutrinos. The discovery was announced on 22 November 2013. In this episode we talk with DESY's Markus Ackermann about the the evidence for astrophysical neutrinos and why they are important. We also discuss how the the IceCube Neutrino Observatory works, which opened up this new field of astronomy. We conclude with a brief conversation about traveling to, and living at the south pole, where IceCube is located.
