A Tour Around the Summer Triangle with Jeff Miller -

7 p.m. Friday July 31

The Summer Triangle is marked in the sky by a bright star in each of three constellations: Cygnus, the Swan; Aquila, the Eagle; and Lyra, the Harp. Each constellation contains beautiful and mysterious objects: colorful stars, the remains of an exploded star, a black hole. We’ll use planetarium software to explore these objects and we’ll learn about the Greek mythology behind these constellations. As a bonus, we’ll find the current location of Comet NEOWISE.

Einstein, Eclipses, and Multimessenger Astronomy with Dr. Aileen O'Donoghue -

7 p.m. Friday August 7

Dr. O’Donoghue will touch on the basics of Einstein’s General Relativity, including confirmations of the theory by solar eclipses (including the one coming in 2024) and GPS satellites. She will explain gravitational waves, their detection by the Laser Interferometer Gravitational Wave Observatory (LIGO), what events they, satellite and ground-based observatories have revealed about the universe and why this is a new era in astronomy.

Spectroscopy of Stars: Riddle in the Rainbow

7 p.m. Friday August 14

Presented by Joshua Thomas, Assistant Professor/Director of Reynolds Observatory from the Department of Physics of Clarkson University.

Josh will give a brief introduction to the entire rainbow of light, how it's measured, and what astronomers learn from it. The audience will hear a little about types of stars, and how we know the chemical compositions of stars, and how we know how fast stars are going. The talk will round out by solving the riddle of what information stellar rainbows contain.
