Abstract

The discovery of exoplanets is a small part of the array of scientific arguments for and against the existence of extraterrestrial intelligence. Yet the recent stunning achievement of this program of observational astronomy has had a significant effect on scientific opinion and public interest. It also raises some key theological questions. New observing techniques are leading to the discovery of extrasolar planets daily. Earth-like planets outside of our Solar System can now be identified and in future years explored for signs of life. This article maps the history of these discoveries and highlights some of the theological issues which are important to bring into dialogue with these scientific insights.
