The Search for 100 Earths

The Search for 100 Earths

Yale astronomer Debra Fischer has spent decades hunting for exoplanets. Now she leads the 100 Earths project that includes the Lowell Observatory and astrophysicist Joe Llama. Debra and Joe join us for a conversation about this search for worlds that could be like our own. There’s big space news in this week’s edition of The Downlink at the top of the show, and Bruce Betts takes us on his weekly tour of the night sky, though it’s the pre-dawn sky that may hold the most wonder. Try your hand at the space trivia contest! Learn more and enter the contest at https://www.planetary.org/multimedia/planetary-radio/show/2020/0226-2020-debra-fischer-joe-llama-100-earths.html
