Astronomy Series: #4 Measuring Distance in the Universe


Adult / Interactive Groups -
Fall 2025

Get ready for a journey across space and time as we uncover humanity’s quest to measure the universe! This engaging course takes you on a whirlwind tour of how people figured out the distances to planets, stars, and galaxies. You’ll discover how ancient Greeks used geometry and lunar eclipses, how Renaissance astronomers harnessed the telescope and planetary parallax, and how 20th-century scientists relied on pulsating stars and exploding supernovae to map the vast cosmos. Along the way, you’ll see how each leap in measurement not only shrank or expanded our sense of the universe, but also rewrote our ideas about its past and its astonishing future.

(the largest amateur astronomy exhibition in the US), York County Star Party (Pennsylvania), NOVAC
star party (Virginia), and other public participation events. He was invited by the NASA Ambassador
outreach program to speak at their total solar eclipse event in Buffalo NY, attended by ~2000
attendees (April 2024). He has presented a number of talks and hosted stargazing parties on several
cruise ships. His broad understanding of astronomy and space activities, ability to explain concepts
at a general public level, and engaging style have made him a sought-after speaker.
