Every second, trillions of ghostly particles called neutrinos move through the universe—and through our bodies, though we don't notice them. A tiny fraction leave a trace in IceCube, the giant cubic-kilometer-deep telescope built into the South Pole’s Antarctic ice to catch them. Neutrinos can escape from the areas around black holes and the hearts of stars, and thus carry information about the most violent processes in the universe—and may shed light on the nature of dark matter. Anna Franckowiak completed her Ph.D. in neutrino astronomy and spent four weeks at the South Pole working on IceCube; she now works at the SLAC National Accelerator Laboratory in Menlo Park, studying astronomy with the Fermi Gamma-Ray Space Telescope.
