 sses the origins and evolution of life in space and time. It is estimated 
 that life started on Earth approximately 3.9 billion years ago. By studyin
 g the evolution of our own planet and Sun\, it may give us some clues as t
 o what to look for life at other locations in our own solar system and in 
 the solar systems of other stars.\n\nComparative planetology tells us that
  terrestrial planetary atmospheres have been in a process of continual cha
 nge within an ever changing solar and galactic environment. We are finding
  some startling parallels that suggest both Venus and Mars had environment
 s that would have been habitable for life in their distant past. New obser
 vations in the outer part of our solar system indicate that Europa and Enc
 eladus have an ocean of liquid water beneath their icy crust in contact wi
 th mineral-rich rock. These icy moons may have the ingredients needed for 
 life as we know it.\n\nWith these discoveries\, and many others in mind\, 
 we are looking for potentially habitable exoplanets and have made some sig
 nificant discoveries.\nSpeaker's Biography:\nJim Green has worked at NASA 
 for 42 years before retiring in December 2022. He received his Ph.D. in Ph
 ysics from the University of Iowa in 1979 and worked at Marshall Space Fli
 ght Center\, Goddard Space Flight Center\, and NASA Headquarters. During J
 im's long career at NASA\, he has been NASA's Chief Scientist and was the 
 longest serving director of the Planetary Science Division with the overal
 l programmatic responsibility for the New Horizons spacecraft flyby of Plu
 to\, the Juno spacecraft to Jupiter\, and the landing of the Curiosity rov
 er on Mars\, just to name a few. He has written over 125 scientific articl
 es in refereed journals and over 80 technical and popular articles. In 201
 5\, Jim coordinated NASA's involvement with the film The Martian. In 2017 
 Asteroid 25913 was renamed Jamesgreen in his honor.
