Neighborhood Lecture Series
Our Neighborhood Lectures provide an opportunity to explore the world from the perspective of scientists who are working at the leading edge of scientific discovery. The lectures begin at 6:30 PM EDT and last for approximately one hour, followed by a brief question and answer period. Please note that registration will be required to access the Zoom webinar. We will also be streaming to our YouTube channel.
What makes a planet habitable?
Speaker: Dr. Anat Shahar (Carnegie Institution for Science, Earth and Planets Laboratory)

Earth is a dynamic planet: from the surface teeming with life to the deepest interior that maintains the protective magnetic field. For over 4.5 billion years, giant impacts, volcanism, and surface tectonic motions have transformed the surface, oceans, and atmosphere. Despite, or perhaps because of, these extrinsic changes, life has thrived. Why is Earth habitable? Where will life be detected elsewhere? What type of planet is most likely to sustain life? Beyond Earth, what are the characteristics of a habitable planet? In one of the great discoveries of our lifetimes, the Galaxy turns out to be teeming with planets. For the first time in human history, we have a wide range of planets to consider as possible hosts for life.
