Alan Stern joined us last April to discuss his book Chasing New Horizons: Inside the Epic First Mission to Pluto, co-written with David Grinspoon. Today we update the 2019 news from New Horizons and replay the interview with Stern. New Horizons captured images (just 33 minutes into the new year) of an icy world at the edge of our universe called Ultima Thule.
