Neutrino Hunters: Searching for Ghostly Particles in Antarctic Ice, with Abigail Vieregg

Episode Summary

Deep beneath the ice of Antarctica and high above its frozen expanse, University of Chicago astrophysicist Abby Vieregg is hunting for neutrinos—some of the most elusive particles in the universe. Often called "ghost particles," these tiny messengers travel across billions of light-years, passing right through ordinary matter unnoticed. She is among the many scientists hunting for high-energy neutrinos—an area of research that was awarded the 2026 Nobel Prize in Physics. In this episode, Vieregg discusses how her team designs and launches cutting-edge radio detectors—from high-altitude NASA balloons over the South Pole to massive ice-drilling arrays in Greenland. She explains what these mysterious cosmic signals can teach us about black holes, exploding stars, and the fundamental laws of physics governing our universe.
