LVAAS General Meeting

Sunday February 5, 3 p.m. at Muhlenberg College

Trumbower Science Building, Room 130

and on Zoom


A History of Lunar Observation and Exploration


Gary DeLeo

Emeritus Professor of Physics, Lehigh University

As a child of the 1950’s and 60’s, Gary has been awed by the observations and explorations of our nearest solar-system neighbor, the Moon. He will describe the evolution of our understanding of the Moon, beginning long before he was born, going through centuries of telescopic observations, and through missions to explore the surface of the Moon. Gary will include facts, and some fiction, both insightful and ridiculous. He will bring us up to date on recent robotic missions and, hopefully, a human return to the Moon.

Professor Gary DeLeo was a member of the Lehigh University faculty in the Department of Physics for forty years before retiring at the end of 2019. He received his Ph.D. from the University of Connecticut with a specialty in theoretical solid-state physics. He has served as Associate Dean in the College of Arts and Sciences, and as Chair and Associate Chair of the Department of Physics. His passion for astronomy – a field that he has followed closely for about fifty years – led to his change in research area to astrophysics, with a focus on binary stars. Professor DeLeo has run a significant number of science outreach programs, and he is the recipient of seven teaching awards and honors.

THE LEHIGH VALLEY AMATEUR ASTRONOMICAL SOCIETY -- 620B East Rock Road -- Allentown, PA 18103 -- 610-797-3476 --


Founded in 1957, the Lehigh Valley Amateur Astronomical Society (LVAAS) is one of the oldest continuously-operating amateur astronomy organizations in the U.S. The mission of LVAAS is to promote the study of Astronomy and to maintain a meeting space, observatories, and a planetarium.

LVAAS operates two astronomy sites: The South Mountain site in Salisbury Township is the headquarters of the Society. It has a planetarium with a Spitz A3P projector, a 21 foot dome, meeting space, the Red Shift store, library, workshop space, and three observatories. The Pulpit Rock site near Hamburg is LVAAS's members-only dark sky site. At 1600 feet above sea level, the site features five observatories and a pad for member's scopes.

Members who receive training on the scopes may obtain keys to the observatories. LVAAS also maintains a rental "fleet" of telescopes that members may rent at low cost. Members also receive access to The Observer, our online newsletter, as well as reduced subscription prices to Sky and Telescope and Astronomy Magazine. If you want to learn more about astronomy and LVAAS, please join us at our next public star party.
