SUMMARY:HYBRID – General Meeting – May 2026
DESCRIPTION:Title:  All About Asteroids\n\n\n\nIn 1801\, Ceres became the first asteroid ‘discovered.’ (it was since reclassified as a dwarf planet.) Since then\, astronomers have used widely differing approaches to learn about the nature of asteroids. Nearly all of them are point sources that show no details through the largest telescopes. And so\, several clever methods to determine their properties have evolved. These include photometry\, radar imaging\, and stellar occultations. Tom Polakis’ presentation will range from the history of asteroid discoveries to the latest science about them and what future projects are planned. He will show samples of his techniques to study and photograph asteroids \n\n\n\nPresenter: Tom Polakis\n\n\n\nTom Polakis has been an active amateur astronomer for 48 years\, during which has seen Saturn circle the sun 1 1/2 times.  He is a member of Saguaro Astronomy Club and East Valley Astronomy Club in Metro Phoenix. A graduate of Michigan State University\, and a retired mechanical engineer\, Tom’s main interests involve visual observing of all astronomical phenomena\, and imaging them with equipment ranging from a phone to a backyard observatory.  He has a special interest in describing the universe as an ever-changing entity.  His writing and photography have regularly appeared in magazines such as Astronomy and Sky & Telescope. More recently\, he has been an author or co-author for refereed astronomical publications.

SUMMARY:HYBRID – General Meeting – April 2026
DESCRIPTION:Title:  TAAA Dark Sky Sites…A Great Club Perk!\n\n\n\nTAAA Members Jim Knoll\, Bill Lofquist\, and Stephen Ferris will speak about the exciting opportunities for dark site viewing available for TAAA members at TIMPA (which stands for Tucson International Modelplex Park Association) and at CAC (Chicahua Astronomy Complex)  \n\n\n\nTIMPA is just 25 miles west from the center of Tucson. TAAA has used the site for almost 30 years.  It includes restrooms\, 6 user pads\, and the club’s original big telescope\, the 14″ Gila Monster observatory.  TIMPA Director\, Stephen Ferris reports that “in the last two years\, we’ve also added a second permanently mounted big telescope\, the TIMPA Meade 16″ SCT.  Late last year\, we also acquired a Losmandy G11 mount which we are matching with two high quality refractors and an ASIAir control unit.” TIMPA now can welcome SmartScopes of all types.  SmartScopes are a great new tool for both beginning and experienced astronomers. TIMPA is planning multiple events for SmartScopes in the next few months. This close-in site opens at sunset\, and members can stay until dawn.   \n\n\n\nPresenters:  Jim Knoll and Bill Lofquist\n\n\n\nJim Knoll and Bill Lofquist will give the latest information about TAAA’s very own 16-acre CAC observing site. CAC is two hours SE of Tucson near the Chiricahua Mountains. From here you can easily see the Milky Way and many astronomy objects with just your eyes. Telescopes at the site include a 40-inch\, 32-inch\, 25-inch\, 18-inch\, several 14-inch scopes\, a 9-inch refractor and many more. CAC has 10 sleeping rooms\, 7 RV sites\, a large tent camping area\, and a classroom.   \n\n\n\nLearn about the history and current availability of both observing sites at the April TAAA meeting.

SUMMARY:HYBRID – General Meeting – March 2026
DESCRIPTION:Title:  A Cosmic Odyssey: The Epic Journey of our Milky Way Galaxy \n\n\n\nAstronomers estimate that approximately one in a thousand galaxies in the nearby universe is in the act of colliding. Although rare locally\, we find that galaxy mergers were far more common and produced the majority of all the infrared emission in the early Universe. Therefore\, studying these rare mergers in our local Universe gives us a window into the galactic train wrecks of the early Universe that shaped galaxy evolution. It has been over 100 years since astronomer Vesto Slipher discovered that\, unlike every other galaxy we observe\, our nearest neighbor\, Andromeda\, is on a collision course with the Milky Way. In order to understand the fate of our galaxy\, observations of hundreds of ongoing galaxy mergers\, with have been collected\, with every major space-based observatory available—e.g. Hubble\, Spitzer\, Herschel\, GALEX\, Chandra\, and JWST— as part of the Great Observatories All-Sky LIRG Survey (GOALS). These luminous infrared galaxies host the most extreme dust-enshrouded stellar nurseries in the local Universe. In this talk\, Dr. Sean Linden presents the story of the Milky Way Galaxy; how the ongoing interaction with Andromeda has shaped it so far\, and what we have learned about galaxy mergers in GOALS that allow us to predict what the Milky Way will look like in the future. \n\n\n\nPresenter:  Dr. Sean Linden\n\n\n\nDr. Sean Linden received his PhD in the Spring of 2020 from the Department of Astronomy at the University of Virginia working with Dr. Aaron Evans and Dr. Eric Murphy at the NRAO. He then moved to a position as a postdoctoral researcher at the University of Massachusetts Amherst for three years working with Dr. Daniela Calzetti on studies of star clusters in nearby galaxies with JWST. Sean is currently the Peter A. Strittmatter Prize Postdoctoral Fellow at the University of Arizona\, and will be starting a new position as an assistant professor in the School of Physics and Astronomy at Rochester Institute of Technology next Fall.

SUMMARY:HYBRID – General Meeting – February 2026
DESCRIPTION:Title:  NASA’s Europa Clipper Mission: On the Way to Explore Ocean World Habitability\n\n\n\nDr. Robert Pappalardo\, Project Scientist for the Europa Clipper Mission\, gives this month’s featured talk. In his words: “On October 14\, 2024\, NASA’s Europa Clipper spacecraft launched on its journey to Jupiter’s moon Europa\, an icy world believed to harbor a global subsurface ocean. Observations from the Galileo mission revealed Europa to have a relatively young and deformed ice surface. An induced magnetic field implies the presence of a salty ocean beneath the ice. Tidal forces from Jupiter fracture the ice shell into ridges\, bands\, and chaotic terrains\, suggesting ice mobility and possible local melting. Earth- and space-based telescopes suggest the presence of plumes that may vent interior water vapor into space. Europa may contain the key ingredients necessary for life—liquid water\, bioessential elements\, chemical energy\, and long-term stability—making it a compelling target for investigation of ocean world habitability. \n\n\n\nThe Europa Clipper mission will address Europa’s habitability using an advanced suite of remote-sensing and in-situ instruments that probe the moon’s interior\, composition\, and geology\, while also searching for present-day activity such as plumes. During its 5.5-year cruise to Jupiter\, the mission is maturing operations concepts and validating instrument performance\, including through flyby observations of Mars\, Earth\, and interstellar comet 3I/ATLAS. After entering Jupiter orbit in 2030\, the spacecraft will execute 49 close encounters with Europa at altitudes of typically 25–100 km above the surface\, enabling unprecedented observations of this ocean world.” \n\n\n\nDr. Pappalardo’s presentation will summarize our current understanding of Europa\, describe how Europa Clipper is designed to investigate its habitability\, and provide an update on mission status as the spacecraft continues its journey to the Jovian system. \n\n\n\nPresenter: Robert Pappalardo \n\n\n\nRobert Pappalardo is a JPL Fellow and Senior Research Scientist\, and the Project Scientist for NASA’s Europa Clipper Mission at the Jet Propulsion Laboratory\, California Institute of Technology. He has also served as the Project Scientist for the first extended mission of the Cassini spacecraft at Saturn\, for which he received NASA’s Exceptional Service Medal. He received his B.A. in Geological Sciences from Cornell University in 1986\, and he obtained his Ph.D. in Geology from Arizona State University in 1994. His research focuses on processes that have shaped the icy satellites of the outer solar system\, especially Europa and the role of its probable subsurface ocean. He has co-authored over 150 peer-reviewed journal papers and book chapters\, and he served as the chief editor of the University of Arizona Press book Europa. Through the years\, Pappalardo has mentored students and post-docs\, and he has worked with various science museums and organizations to bring the excitement of astronomy and planetary exploration to the public. \n\n\n\nPhoto Caption: Dr. Robert Pappalardo\, Project Scientist for NASA’s Europa Clipper Mission \n\n\n\nPhoto Credit: Johns Hopkins Univ.
