Are we alone? Or are there other worlds out there, like the Earth, that can support life? The field of exoplanet research has seen unprecedented progress over the last decade with over 3500 planets now been detected outside our Solar System. Further more, this number is expected to rise exponentially over the next few years with new and improved ground- and space-based telescopes set to take center-stage. Recent advances on this front suggest that small, Earth-sized, planets are abundant in our galaxy with many thought to lie in the host star’s habitable zone where the conditions on the planet are optimal to have liquid water on the surface. This realization, coupled with the ongoing discovery of new organisms on Earth in environments previously thought to be inhospitable for life, suggests that extraterrestrial life could be far more commonplace than previously imagined. In this talk, Dr. Hegde will explore some of the methods that can be used in characterizing an Earth-like planet for potential habitability and life by providing a link between geomicrobiology and observational astronomy.
