Hello! Is anyone out there? As the scientific search for extraterrestrial intelligence marks its 50th anniversary, there’s been no contact as yet with alien beings. But SETI researchers maintain that we are not alone. Find out why in a SETI retrospective that looks at the past and future of the search.

We remember the first scientific SETI search… Carl Sagan… how the SETI Institute began… the WOW signal…and the 1993 NASA budget cuts.

We’ll also hear from critics of the search… scientists involved in optical SETI and SETI@home. Plus, international collaborations… and where the search is headed.

Guests:

  • Frank Drake – Director of the Carl Sagan Center for the Study of Life in the Universe, SETI Institute
  • Jill Tarter – Director of the Center for SETI Research, SETI Institute
  • Tom Pierson – CEO, SETI Institute
  • Paul Horowitz – Physicist, electrical engineer, Harvard University
  • Dan Werthimer – Chief Scientist, SETI@home, University of California, Berkeley
  • Ben Zuckerman – Physicist, Astronomer, UCLA

Podcast also available on PocketCasts, SoundCloud, Spotify, Google Podcasts, Apple Podcasts, and RSS.
