Who hasn’t looked up at the stars at some point and thought maybe there are other intelligent creatures out there? Astronomers scan the cosmos and they’ve found plenty of intriguing but inconclusive signals so far. Are they no more than magnetic waves from far off dead planets, or something more?

Dr. Franck Marchis, Senior Planetary Astronomer at the SETI Institute (Search for Extraterrestrial Intelligence), tells Luke Turner about the groundbreaking research the institute is doing and how you can play your part in the search for extraterrestrial intelligence.

Guest: Dr Franck Marchis
