This talk explores the science surrounding the most important topic in Astronomy today, Exoplanet research. When we find alien Life we will find it not by listening for intelligent signals since these signals are lost amidst the galactic noise after traveling only 100 light years, but by looking for and finding Exoplanets with life signs evident in their imagery. The talk will answer questions such as: What are these “life” signs? How do we find them? What will it mean to us? Will we find another Earth? How likely is Life? These and more questions will be answered. Participants will leave armed with real science knowledge they can use to understand the methods we use to find ET.
