MAS January Monthly Meeting

Curiosity Paving the Way for Perseverance

Dr. Rebecca Williams

Understanding the past habitable conditions on Mars is a primary scientific driver for NASA’s Curiosity rover. During the last eight years, Curiosity has traversed across diverse terrain within Gale crater and drilled the martian surface over two dozen times. Dr. Williams will provide an update on the latest scientific findings and share spectacular snapshots from along the rover’s journey. In addition, she will present an overview of NASA’s next robotic mission to Mars, Perseverance, which will land at Jezero crater in February 2021. 

Rebecca M. E. Williams is a planetary geologist who studies the history of water on Mars through orbiter and rover observations in conjunction with field-based analog studies on Earth...

MAS December Monthly Meeting

MAS Telescope Clinic graphic

MAS’s annual telescope clinic is a chance for people in the Madison area to get their questions answered about telescopes and binoculars. It may also help you with some ideas for the gift-giving season.

Do you have an old telescope that’s gathering dust because you don’t know how to use it?Or are you looking to buy a new one? Whatever the case, join us Friday online and learn something. MAS members will be on hand to answer your questions about your existing telescope or give you ideas for your next purchase.

The December meeting will be a virtual event, hosted with Zoom. Members will receive an email with a link and instructions to join a day or two before the event.

This month we are opening the virtual meeting up to non-MAS members who may want to attend the meeting...

MAS November Monthly Meeting

Whispers from the Universe: Astronomy with Gravitational Waves

Dr. Patrick Brady, LIGO, November Meeting Speaker

Dr. Brady will talk about the generation of gravitational waves by colliding black holes and neutron stars, and how they are measured here on Earth using the LIGO detectors. He will tell the story of the first detection of gravitational waves in 2015, for which the Nobel Prize was awarded in 2017, through to the exciting observations that are becoming almost routine.

Patrick Brady received his B.Sc. from University College Dublin in 1988 and a Ph.D. in Physics from the University of Alberta in 1994 where he studied with Werner Israel. He has held research positions at the University of Newcastle-upon-Tyne, Caltech, University of California, Santa Barbara...

MAS October Monthly Meeting

Insterstellar laser-sailing: problems and solutions

October MAS Speaker: Dr. Victor Brar

The October MAS meeting will be a virtual meeting hosted with Zoom.

Speaker: Victor Brar, Van Vleck Assistant Professor of Physics, UW-Madison.

In this talk Dr. Brar will summarize recent efforts that have been put into motion which aim to send spacecraft to Alpha Centauri at relativistic speeds, with a goal of receiving data back within our lifetimes. Those proposed missions hinge on developing laser sail technology, in which a high power (~100GW) laser propels a reflective spacecraft. He will discuss the stringent design parameters that the spacecraft must satisfy, and describe how those parameters can be achieved using recently developed ‘metasurface’ technology.

MAS September Monthly Meeting

Copernicus: A Life on the Frontiers

MAS September Meeting with Dr. Michael Shank

The September MAS meeting will be a virtual meeting hosted with Zoom.

UW Madison emeritus professor of the history of science Dr. Michael Shank will present on “Copernicus: A Life on the Frontiers.”

Description: An unexpected invitation to write a general-audience biography of Copernicus has forced this historian of medieval science to wrestle anew with the founding figure of the Scientific Revolution. I expected the assignment to be quick and easy. Instead, it has driven me back to the sources and completely changed my picture of the man. Copernicus was far more buffeted by Baltic politics and indebted to his late-medieval background than I had ever expected...

MAS August Monthly Meeting

A Brief History of Time(keeping): Optical atomic clocks and their applications

Image of an optical atomic clock

At the August MAS meeting, our guest speaker will be Shimon Kolkowitz of the UW-Madison physics department (assistant professor). Due to COVID-19 restrictions, this meeting will again be held via Zoom.

Optical atomic clocks are now the most stable and accurate timekeepers in the world, with fractional accuracies equivalent to neither losing nor gaining a second over the entire age of the universe. This unprecedented level of metrological precision offers sensitivity to new physics phenomena, opening the door to exciting and unusual applications...

MAS July Monthly Meeting

Solar System Remnants

Jordan Marché

The July meeting of the Madison Astronomical Society will again be held online. Our guest speaker is Jordan Marché of the UW Madison. Jordan’s talk is entitled: “Solar System Remnants.”

The ‘golden age’ of planetary exploration continues unabated. Along with all of the major planets and their principal satellites, spacecraft have explored the dwarf planets Pluto and Ceres, the Kuiper Belt Object Arrokoth (formerly Ultima-Thule), together with a number of large and small asteroids and comets. This talk presents an overview of many of the latest surveys and discoveries concerning these ‘minor’ members of the Solar System, along with implications for how they have redirected the evolution of life here on Earth...

MAS June Monthly Meeting

MAS History Project – MAS Turns 90

UW Students' Observatory from the mid-70s

The Madison Astronomical Society is turning 90 next year. All this spring the History Committee has been delving into the archives, interviewing surviving members, pouring over newspaper microfiche, and turning over rocks. Come see some of the surprises we’ve discovered.

This photo was shot at the Oscar Mayer Observatory (in Fitchburg) sometime in the mid-1970s by one of the Explorer Post Scouts. This observatory used to be the UW “Students’ Observatory” and from 1880 to 1960 sat on Observatory Hill right beside the Washburn Observatory...

MAS May Monthly Meeting

Mining the Spitzer Space Telescope Data Archive for Dust

MMSD Planetarium Team

Geoff Holt was accepted into the NASA/IPAC Teacher Archive Research Program (NITARP) this past year which teamed him up with other teachers around the country and an astronomer from CalTech/JPL. This program aims to give teachers experience doing actual astronomy research, and they can get students involved if they wish. Over the past year, Geoff and five James Madison Memorial High School students have been participating in this research team. Their goal has been to mine the Spitzer Space Telescope data archive in search of sources that have an excess of infrared light compared to a black body curve...
