Calling All Aliens

Are we alone in the universe? Is there other intelligence out there? COSMIC, the most ambitious SETI search yet, hopes to answer that. We hear updates on this novel signal detection project being conducted on the Very Large Array in the desert of New Mexico. Also, we chat with award-winning science fiction writer Ted Chiang about how he envisions making contact with aliens in his stories, including the one that was the basis for the movie Arrival. And find out why some scientists don’t want only to listen for signals, they want to deliberately transmit messages to aliens. Is that wise and, if we did it, what would we say?  

Guests: 

Chenoa Tremblay – Postdoc researcher in radio astronomy for the SETI Institute and member of COSMIC science team 

Ted Chiang – Nebula and Hugo award-winning science fiction writer, best known for his collections, Stories of Your Life and Others and Exhalation 

Douglas Vakoch – Founder and president of METI International, a nonprofit research and educational organization devoted to transmitting intentional signals to extraterrestrial civilizations 

Featuring music by Dewey Dellay and Jun Miyake
