CANCELED: Free Astronomy Lecture | Castro

Once monthly, the SFAA hosts distinguished guest speakers who are leaders in the fields of astronomy, physics and related disciplines and they present to SFAA Members the latest developments from cutting-edge scientific programs.

Held in the Randall Museum Theater on the third Wednesday of every month, come early for coffee and a light snack at 7:30 PM followed by the general meeting at 7:45 PM. The lecture begins at 8:00 PM.

Objects with masses (<0.08 solar masses) too small to sustain hydrogen fusion were theorized to exist five decades ago, and discovered 30 years later, due to their extreme faintness. Even less massive (<13 Jupiter or <0.01 solar masses) are the planetary mass objects (PMOs), so-called because they are not orbiting a star. We have discovered large populations of such free-floating PMOs and brown dwarfs in the nearest star-forming regions to Earth, when they are at their brightest and most amenable to detection. Do such objects outnumber the stars in the Galaxy? Do they have their own planetary or moon systems? Could these sustain surface or subsurface liquid water for eons via tidal heating and thus provide environments conducive for the development of microbial life?

Dr. Mary Barsony is a Principal Investigator at the Carl Sagan Center for the Study of Life in the Universe at the SETI Institute and Adjunct Professor of Physics and Astronomy at San Francisco State University. She has served as a faculty member at USC, Harvey Mudd College, and U.C. Riverside. She earned her Ph.D. in physics from Caltech,and her S.B. in physics from MIT.
