That’s So Second Millennium

Episode 082 - Extraterrestrial Life and Biosecurity with Jonathan Lunine

October 21, 2019

In this week's episode, we discuss the possibility of extraterrestrial life in our own solar system. Dr. Lunine talked about extraterrestrial life. It’s very possible that at least microbial life exists on other planets, he said, but the chances of complex, multicellular life are much more difficult to estimate.

We simply don't know what the possibilities are for life beyond the chemistry that it uses here on Earth. A potential tragedy that we would want to avoid at almost any cost would be the introduction of terrestrial microbes into a viable environment elsewhere, where they could become invasive species, grow and potentially outcompete the native life, which we would never get the chance to study and understand. NASA and other space agencies have policies in place to address this risk... hopefully, they will work.

Dr. Jonathan Lunine is the David C. Duncan Professor in the Physical Science and chair of the Department of Astronomy at Cornell University. He is also the vice president and a co-founder of the Society of Catholic Scientists.

Christianity and Extraterrestrials?: A Catholic Perspective , by Marie George, is a book worth reading, Dr. Lunine said.

He thanked all those who spoke at the 2019 conference of the Society of Catholic Scientists, and he commented on the high quality of the event. The website provides links to several TSSM episodes interviewing conference speakers.
