Observational searches for exoplanets and statistical properties

Explore the Drake equation's implications for the ubiquity of life, focusing on direct imaging, microlensing, astrometry, and other observational methods in the search for exoplanets. Learn about the Kepler Mission's aim to discover Earth-like planets through photometry of numerous stars.
