Jay Pasachoff visits Planetary Society headquarters for a conversation about the latest edition of his and Alex Filippenko’s monumental textbook The Cosmos.  But that’s just the start of a discussion that explores solar astronomy, art and science, the history of astronomy and Jay’s nearly 60-year history of total solar eclipse observations.  The Planetary Society’s LightSail 2 may look like LightSail 1, but Jason Davis tells us there are important differences between these spacecraft, beginning with their missions. What’s Up brings another opportunity to win Alan Stern’s great book, Chasing New Horizons in the space trivia contest.  You can learn more about all of this week’s topics at:  http://www.planetary.org/multimedia/planetary-radio/show/2019/0529-2019-jay-pasachoff.htmlLearn more about your ad choices.
