Answering Questions About Supernovas, with Michael Shara

When will the last supernova be? Neil deGrasse Tyson and Chuck Nice explore types of novas, freaky binary star systems, core collapse, standard candles, and the explosive future of Betelgeuse with astrophysicist Michael Shara. What’s the difference between a nova and a supernova? We explore the taxonomy of stellar explosions: dwarf novae, supernovae, hypernovae, and kilonovae. How can a white dwarf explode again and again without being destroyed? Why are some stars cannibals in binary systems? We explore neutron stars, black holes, and the deadly elegance of core collapse supernovae. What makes a pulsar pulse? Can some stars just disappear in a “dark supernova”? And what can a kilonova teach us about gold, platinum, and the origins of nitrogen in every breath we take? Plus, when will Betelgeuse explode? What’s a standard candle? We break down this vital method of measurement for astronomers and how it works. Can a star outshine the Moon? When will the last supernova go off? What shuts down star formation in galaxies? And why are astronomers obsessively watching the star T Coronae Borealis right now? All that, and more exploding-star goodness in this stellar episode of Cosmic Queries.
