Zoe Todd
UW Madison
Assistant Professor of Chemistry and Astronomy
Dr. Todd delves into the origins of life on Earth, exploring its implications for the potential existence of life on other planets. Her interdisciplinary research aims to comprehend how the astronomical and planetary environments might facilitate the chemical and biochemical origins and evolution of life.

John Valley
Professor emeritus, UW Department of Geoscience
Dr. Valley has been a guest speaker at MAS meetings many times over the years. His topics have ranged from Martian meteorites discovered in the Antarctic to the age of the Earth. Dr. Valley never fails to enthrall his audience with what can be learned from the minute examination of rocks.
Watch this space for details of Dr. Valley’s June presentation to the MAS.

Quite recently, only the brainiest and most dedicated uber-nerds dared to tread into astroimaging. The laws of physics haven’t changed, but in every direction, the barriers to entry have nevertheless fallen. First-class optics, precision mounts, amazing sensors, and simply incredible advances in software are in reach for just about anyone. If you thought astrophotography was too hard or too expensive, see what you think after we explore the current state of play.

Maxwell Kroft
How do astronomers discover and characterize exoplanets? It’s not as straightforward as spotting them with a telescope, like you do with stars on a clear night in a park. In this presentation, Max will delve into the methods astronomers employ to measure various aspects of exoplanets, primarily by observing their impact on their host stars. He’ll also share his research on exoplanets conducted using the WIYN 3.5m telescope at Kitt Peak, Arizona.

Mistakes and Second Chances
John Rummel
Photographic mistakes take many different forms. Some can be very expensive. Like when you’ve traveled thousands of miles to be in the exact location, at the exact time, to take a very specific shot. When you screw it up, second chances can be difficult to arrange, or may just be impossible.
In this March meeting presentation, John Rummel will talk about a multi-year plan to be in that spot, to take THAT shot, and how it all went wrong.

By sharing their personal stories of how their interest in astronomy began and how, 4,000 miles apart, those stories led them to MAS and a lasting friendship, Avtar and Jeff hope to engage the audience in a conversation about their own beginnings and journeys into amateur astronomy.
Special treat – Avtar and Jeff will bring their first telescopes (which both still have) to share with the audience.

The design for this unusual telescope, which features a polar-aligned, fixed eyepiece, takes me back several decades. At the time, I was investigating warmed-room observatories, many of which had been featured in the well-known Amateur Telescope Making book series (three volumes). One of the simplest of these had been constructed by Russell W. Porter (1871–1949), principal founder of the amateur telescope making movement, which (in the U.S.) began in the early twentieth century.

“Perspectives” examines relative distances in the universe and the possible distances achievable through manned and unmanned space flight and through amateur and professional telescopic observation. Examining scales from the human altitude record to the four cosmological horizons, the program discusses astrophysicists’ current thinking about several significant questions:
