Chasing Darkness: Total Eclipses of the Sun and The Great American Solar Eclipse of  April 8, 2024

February 22 @ 7:00 pm - 8:30 pm

Dr. Laurence Marschall, Professor of Physics Emeritus, Gettysburg College, returns to The Institute annually to discuss a topic of astronomical interest. Dr. Marschall has provided fun, educational and entertaining astronomy programs for us for many, many years!

Dr. Marcshall has relocated out of the area, and we are delighted to offer his program virtually.
Arranged in partnership with the Tri-State Astronomers, the program is free and offered via Zoom. 

Chasing Darkness: Total Eclipses of the Sun and The Great American Solar Eclipse of April 8, 2024

“Total eclipses of the sun are among the most wondrous and awe-inspiring of celestial events, but they don’t often occur in convenient locations,” Dr. Marschall said.

Eclipse chasers normally have to travel to exotic spots like Siberia, Southern Africa, or Central America to experience a few minutes of blissful darkness, but we are fortunate, this year. On April 8, 2024, the shadow of the moon will sweep across the entire United States from the Texas-Mexico border through the midwest to upstate New York and New England over the course of several hours, bringing totality to many major population centers.

“In this colorfully-illustrated talk, we’ll explore the astronomical nature of solar eclipses, their historical significance, and their significance in the scientific age. We’ll also give tips on how and where to view the eclipse and what to watch for before, during, and after totality,” Dr. Marschall said.

A professor of astronomy and physics for many years, Marschall was a visiting research scientist at the Harvard-Smithsonian Center for Astrophysics, the University of Canterbury in New Zealand, and at Yale University Observatory. He wrote The Supernova Story, published by Princeton University Press. Marschall has a bachelor’s degree in engineering physics from Cornell University and a Ph.D in astronomy and astrophysics from University of Chicago.
