ABOUT THE LECTURE:  

Astrobiology is the study of life in the universe: its fundamental nature, origins, evolution, distribution and ultimate fate. The search for life beyond Earth is central to this discipline. In this talk, I will discuss how extraterrestrial life may be discovered. If life exists on Mars, in the subglacial oceans of the outer solar system, or on exoplanets, it is likely to produce biosignatures: proxies that we can detect even if we can’t get the organisms themselves under a microscope. But what are biosignatures? How can we find them? And what are the pitfalls?
