New Horizons flew past Pluto in 2015 but work continues on discovering its secrets. One area of study is the activity of so called cryovolcanoes, icy mounds spewing liquidy water and reshaping Pluto's surface. Dr. Kelsi Singer, deputy project scientist for New Horizons, joins Jake to talk about her recent paper on the subject.
