discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. -
Astrochronology: Using Earth’s Astronomical Motions as a Geological Timekeeper and Planetary Decoder
Friday, November 13, 2026, 7 pm, Memorial High School
Dr. Stephen R. Meyers
Vilas Distinguished Professor of Geoscience at the University of Wisconsin-Madison
The long history of our planet provides a rich tapestry of boundary conditions and past ‘experiments’, which can be used to understand how the Earth System works and can inform decisions about our future. But how do we decode that history from a complex geological record?

The Music of the Spheres – Peering Inside Stars with Asteroseismology
Friday, October 9, 2026, 7 pm, Memorial High School
Rich Townsend
UW-Madison Dept of Astronomy
One hundred years ago, the British astrophysicist Sir Arthur Eddington wrote that “Our telescopes may probe farther and farther into space, but they cannot penetrate a solid boulder; and the surface of a star acts as an equally impenetrable shield hiding all that goes on beneath.”
This would seem to suggest that stellar interiors are forever hidden from empirical scrutiny. However, the late decades of the 20th century saw the development of a new technique — “asteroseismology” — that overturns this notion.

Building a Collapsible Telescope
Friday, Sept 11, 2026, 7 pm, Memorial High School
Keith Swartz
Telescopes come in all sorts of shapes and sizes. Changing their shape and size is not easy, if possible at all, but Keith Swartz tells the story about how he modified his homemade 10-inch Dobsonian telescope to better suit his needs. Following the tradition of a few recent speakers, he will also share a bit about his journey with this great hobby.
Keith Swartz is a recently retired mechanical engineer. He is originally from Iowa, but has lived in Madison for 26 years, where he and his wife have raised three kids.
