Michael Person – Seasonal Change on Pluto & Triton

Join us in the WAS Classroom on October 20, 2026 for this live lecture with Dr. Michael J. Person. The event will be live-streamed on YouTube and as a Webinar on Zoom, but we’d love to see you in the classroom at the Westport Observatory. As always, the talk will be posted on our YouTube channel afterwards.

Dr. Person will discuss the use of stellar occultations to monitor the tenuous atmospheres of Plkuto and Triton.

Michael Person is a senior lecturer & research scientist with the Department of Earth, Atmospheric, and Planetary Sciences and director of the George R. Wallace, Jr. Astrophysical Observatory at the Massachusetts Institute of Technology. Dr. Person is an observational astronomer studying the atmospheres, compositions, and shapes of distant bodies in our solar system. His work centers on stellar occultations, eclipses, and transits — using high-precision astrometry and high-time-resolution photometry to measure objects that are otherwise too small or too far away to resolve from Earth.
