MAS October Meeting

Increasing Vision

Rick Wayne, October 2023 MAS Speaker

A photographer’s personal journey into deep-sky astrophotography, from mild interest through the slow but inexorable descent into madness. Lessons learned. Pitfalls explored (from the bottom). Equipment choices, techniques and resources for beginners: how to put a toe in the deep-sky or planetary waters and avoid most of the piranhas.


Rick Wayne is a husband, a dad, and a software engineer for UW Soils, where he writes agronomic decision-support software (motto: “Sweet Bog where do I put all these tons of cow poop?”)

He is an Outdoor Emergency Care instructor and runs the regional instructor-development program for the Ski Patrol, and holds National Appointment #11910...

MAS September Meeting

Why Solar Eclipses Matter and Why Totality Matters More Than Anything

MAS September 2023 Meeting: John Rummel speaking on solar eclipse preparation

There are two important solar eclipse events coming up: the October 14 2023 Annular Solar Eclipse, and the April 8 2024 Total Solar Eclipse. This talk will be a general introduction to solar eclipses with a quick look back at the August 2017 event (seen by many MAS members) but a thorough look ahead to the two upcoming events. Why should you care and how should you prepare? Everything you need to know about planning for and then observing these two events will be covered.

John Rummel is a long-time member and past president of the Madison Astronomical Society. He made his reservations for a place to stay in Texas nearly 3 years ahead of the April 2024 total eclipse!

This meeting will take place in-person at ...

MAS August Meeting

The James Webb Space Telescope Peers Back In Time 43 Minutes

MAS August 2023 Meeting

Though we may think of the James Webb Space Telescope (JWST) as primarily intended to observe the early universe and the most distant galaxies, it also counts observing bodies in our own solar system as part of its mission. As part of JWST’s Early Release Science program, a group of astronomers and planetary scientists proposed and and was selected to observe the Jupiter system, including its atmosphere, rings, and several satellites. Many of that progam’s observations have now been completed and results are being published...

MAS May Meeting

Cosmic Messengers

Dr. Ellen Zweibel will present "Cosmic Messengers"

At the May 12, 2023 meeting of the Madison Astronomical Society, we’ll have a special presentation by Dr. Ellen Zweibel of the UW Madison Astronomy and Physics departments: “Cosmic Messengers.”

Astronomers have long observed the Universe in visible light and its shorter and longer wavelength cousins. Now, subatomic particles and ripples in spacetime have been added to the mix. I’ll describe how these different sources of information can be pieced together to observe some of the most energetic events in the Universe, now and in the past.

Bio: Ellen Zweibel has been a professor of Astronomy and Physics at the University of Wisconsin since 2003. Prior to that, she served on the faculty of the University of Colorado...

MAS April Meeting

Protecting the Night: Light Pollution Reduction in Madison

John Rummel - MAS April 2023 Meeting Speaker

Could Madison WI be a dark sky community? The Common Council seems to think so and has taken action to this end. This talk will focus mainly on the problem of light pollution generally, how Madison is faring specifically, what the future may hold if we do nothing, and will end with the Common Council’s recent action, and why this is reason for us all to hope.


John is a long-time member and former president of the MAS and has recently taken an active role in advocacy of dark skies and adoption of smart lighting choices in places like Madison.


This meeting will take place in-person at our usual Space Place classroom location (2300 S. Park St., Madison) at 7:15pm. It will also be streamed live to our Youtube channel at

MAS February Meeting

How do bacteriophages interact with their host bacteria in space?
A Presentation by Vatsan Raman, UW Biochemistry

February MAS monthly meeting

Bacteriophages, or ‘phages’, are bacterial viruses that are the most abundant organism on Earth. While phage research has progressed considerably terrestrially, how phages and bacteria interact in microgravity is largely unknown. Microgravity presents enormous challenge for microorganisms, which are greatly affected by gravity to mediate cell-cell and cell-phage interactions. To elucidate these interactions, we explore how T7 bacteriophage interacts with E. coli BL21 in microgravity onboard the International Space Station (ISS)...
