There's evidence that Venus, Earth, and Mars all had oceans of water in their past. Why is Earth the only rocky planet that still has oceans today? Scientists think that part of the reason might have to do with the way some planets are like giant magnets. Join our special guest Dr. Dave Brain to learn more about how water, air, and magnetic planets might help us answer this question.

About the speaker:
Dr. Brain is an associate professor at the University of Colorado Boulder and a researcher at the Laboratory for Atmospheric and Space Physics. He is also the Principal Investigator for NASA's Magnetic fields, Atmospheres, and the Connection to Habitability (MACH) DRIVE Science Center. For more information on the center, click here: mach-center.org
Some of Dr. Brain's research interests include how planetary atmospheres evolve, whether or not magnetic fields are required for habitability, and how the solar wind impacts and shapes planets and their atmospheres.
About the navigator:
Jeremy is a CU Boulder alumnus and works as an education assistant at Fiske Planetarium. He is also a presenter and navigator at Fiske.
