Tracking the Origin of Water on Planet Earth

Life on Earth is comprised of water and organic molecules. University of Arizona planetary science professors Jessica Barnes and Pierre Haenecour discuss how some of these components could exist elsewhere in the solar system and how they contributed to the beginnings of life on our home planet.

Jessica Barnes and Pierre Haenecour spoke with Leslie Tolbert, Ph.D Regent's professor emerita at the University of Arizona. They are the first presenters in this year's UA College of Science public lecture series.
