The question 鈥渨hat is life?鈥澨齣s foundational to biology and especially important to astrobiologists, who may one day encounter utterly alien life, and scientists trying to understand how life arises from nonliving chemicals under natural conditions.

On Thursday, Oct. 26, Professor Carol Cleland will present the听Think! talk "How to Search for Extraterrestrial Life."

If you go

Who: Open to the public
奥丑补迟:听Think! talk "How to Search for Extraterrestrial Life"
When: Thursday, Oct. 26, 7:30鈥9 p.m.
Where: Hellems Arts and Sciences, room 199

While the most popular approach to answering听鈥渨hat is life?鈥澨齣s to provide a definition听of life. Cleland will explain why this approach is mistaken: A scientifically compelling understanding of life presupposes an empirically adequate, universal theory of life, as opposed to definition of life. Unfortunately, a truly general theory of life does not exist, in part because our experience with life is limited to a single example (familiar Earth life).

In the second part of the talk, Cleland will sketch a strategy for searching for alien forms of life without the guidance of a definition or universal theory of life, closing听with an application to NASA鈥檚 fledgling search for extraterrestrial life.
