How and when did life originate on Earth? How many other Earth-like planets exist in our Solar System and universe?

This first of four forums focuses on planet formation and habitability. Invited participants engage with leading scientists as they elucidate their pioneering efforts to discover Earth-like extrasolar bodies that could harbor life. Planetary science experts are exploring the basic physical, chemical, and dynamical aspects that led to the formation of our own Solar System—an event that remains mysterious. Their ultimate goal is to determine if similar processes could be at work in newly discovered exoplanetary systems, which could then help predict Earth-like extrasolar bodies that could potentially harbor life.​
