Methane Dunes on Pluto

Guest: Jani Radebaugh, PhD, Associate Professor of Geology, BYU New Horizons spacecraft sent back the first high-resolution photos of Pluto back in 2015. Looking at these pictures, BYU planetary scientist Jani Radebaugh thought something seemed familiar. Parts of Pluto looked an awful lot like the dunes of Death Valley, California, where she often takes her students on field trips. But Pluto was supposed to a frozen planet, not one with a shifting surface.
