SUMMARY:Online General Meeting – November 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n\n  \nX-raying the Winds of Giant Stars\n\n  \n\n  \n  \n  \nWe are made of stardust—or\, at least in significant parts\, of material produced in giant stars. These giant stars have strong winds that strip away the outer layers of stellar material. To understand giant stars\, astronomers thus need to understand their winds. In this talk\, Dr. Grinberg will explain why astrophysicists use space-based X-ray telescopes such as ESA’s XMM-Newton to study such winds and show how they are using black holes and neutron stars as backlights to make such stellar winds visible. \n  \nPhoto:Friedhelm Albrecht/Universität Tübingen \n  \nDr. Victoria Grinberg is an astrophysicist working in the Netherlands for the European Space Agency (ESA) where she helps ESA communicate with the scientific community. After her PhD in Germany\, her research has taken her around the world – USA\, the Netherlands and again Germany – before accepting her current position. Using space-based telescopes\, Dr. Grinberg is studying the most extreme environments in our Universe: black holes\, neutron stars\, and the winds of the most massive giant stars. She also publishes on sustainability and climate crisis from an astrophysics perspective. In her free time\, Dr. Grinberg creates cartoons about science and academia. \nViews: 72

SUMMARY:Online General Meeting – October 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n  \n  \nThe Dynamic Sky:\n  \n  \nHow We Find Discover and Understand\n  \n  \nStellar Explosions in the 21st Century\n  \n\n \n  \nHumans have recorded the appearance of “new stars” since prehistory\, but only in the last century have astronomers begun to understand their nature as stellar explosions. These “supernovae” provide clues about the lives and deaths of stars\, the formation and evolution of galaxies\, the production and distribution of chemical elements (including those required for life on Earth)\, and even the accelerating expansion of the Universe. \n \nIn the last two decades\, the discovery rate of supernovae has ballooned from hundreds per year to tens of thousands per year\, and in the coming decade\, it will reach into the millions. This explosion can be traced back to the same technological advances behind the Internet age: high-speed telecommunications\, digital imaging\, increased computer processing power\, and machine learning. This presentation will explore the history and future of supernova observations\, with a focus on the technology behind them and the science they enable. \n  \n \n  \nDr. Griffin Hosseinzadeh is a postdoctoral researcher at Steward Observatory at the University of Arizona\, where he studies various types of stellar explosions. He was previously a postdoctoral researcher at the Center for Astrophysics | Harvard & Smithsonian. He received his bachelor’s in physics from UC Berkeley in 2012 and his Ph.D. in astrophysics from UC Santa Barbara in 2018. \n  \n  \nViews: 72

SUMMARY:Online General Meeting – September 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n\n  \nCosmic rays\, antimatter\, dark matter:\n\n\n  \nconnecting the dots\n\n  \n \n  \n\nIn August 1912\, Austrian physicist Victor Hess made a discovery that opened a new window to the most energetic phenomena happening in the universe: he had discovered cosmic rays. Cosmic rays are high-energy charged particles coming from space and striking the Earth from all directions. After a century of transformative discoveries and advancements\, cosmic-ray physics is a lively and interdisciplinary field of research. In recent years\, space-born experiments have delivered many new measurements of cosmic-ray protons\, nuclei\, electrons\, and their antiparticles which generate renewed interest and prompted new open questions. This colloquium will address the main open questions in cosmic rays concerning their nature\, their origin\, and their connection with the dark matter puzzle. Emphasis will be given to the rare antimatter component\, which is a promising discovery tool for new fundamental physics or exotic astrophysical phenomena. \n  \n \n  \nNicola Tomassetti is an astroparticle physicist and space scientist. He is an associate professor at the Department of Physics and Geology at the University of Perugia\, Italy. His research interests include cosmic rays\, dark matter\, antimatter\, heliospheric\, and space physics phenomena. He is part of the Alpha Magnetic Spectrometer collaboration for the search for dark matter and antimatter in space. He teaches introductory physics\, space physics\, cosmology & astroparticles for undergraduate\, master’s degree\, and PhD students. \nViews: 72

SUMMARY:Online General Meeting – August 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n\n  \nThe Backstory of Contact Binary Stars\n\n  \n  \n \n\nContact binary star systems have the remarkable property that they orbit so closely they share a common atmosphere. They are the most common type of eclipsing binary star system. Despite extensive observations over more than a century\, answers to the most fundamental questions have eluded scientists until now: How do they form? How do they survive tranquilly in contact so long? What becomes of them in the end? An outburst in 2008 showed directly that contact binary stars end their long lives by merging in an explosive event known as a red nova. This presentation will reveal the recently uncovered backstory that answers these questions\, and it will conclude by considering how these answers might help identify which contact binary will be the next to explode. \n\n  \nProfessor Larry Molnar earned a B.S. in astronomy from the University of Michigan along with an MA and a PhD in astronomy from Harvard University. (Hence\, he has the three-degree background appropriate for one studying the Universe) He was a postdoc at the Smithsonian Astrophysical Observatory and taught at the University of Iowa. He has been a professor of Physics and Astronomy at Calvin University since 1998. \nViews: 72

SUMMARY:Online General Meeting – July 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n\n  \nRovers on Mars: 21st Century\n\n  \nNatural History\n\n  \nExpeditions to Another Planet\n  \n  \n \n\nPerseverance and Ingenuity are the current culmination of a long list of missions to Mars. During the first 400 days of operation on the surface of Mars Perseverance has traveled over 12 kilometers and Ingenuity has flown 28+ times. In addition to observations focused on understanding the geologic history and context of four+ samples collected for eventual return to Earth at this time\, Perseverance has made a variety of observations of the atmosphere and the moons of Mars. At the time of this presentation we will be well into the exploration of the enormous delta deposited by an ancient river onto the floor of Jezero Crater where Perseverance landed. \n\n\nLarry S. Crumpler\, Ph.D. is Research Curator in Volcanology and Space Sciences at the New Mexico Museum of Natural History and Science. He received his doctorate from the University of Arizona in Planetary Sciences and MS from the University of New Mexico in Geology. Prior to the Museum\, he worked at Brown University.   \nHe is a member of the Perseverance Rover Mission science team where he is responsible for geologic context mapping of the terrain traversed by the rover. Previously\, he was a team member on Ingenuity helicopter development\, Mars Exploration Rover (Spirit & Opportunity) where he served as “Long-term Planning Lead\,” Mars Odyssey Gamma Ray Spectrometer\, and Mars Reconnaissance Orbiter Camera (HiRISE).     \nHe previously participated in NASA’s Viking and Pathfinder Mars\, Magellan mission to Venus\, Russian Mars 96 mission planning\, Mars landing site selection and rover field tests.   He has published numerous research papers\, book chapters\, and geologic maps; and a book about Mars that will be published by Harper-Collins in late 2021.  He is a Fellow of the Geological Society of America. \nViews: 72

SUMMARY:Online General Meeting – June 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n  \n  \nThree Decades of\n  \n  \nthe Hubble Space Telescope\n\n  \n\n \n\nAfter decades of discussion and construction\, the Hubble Space Telescope was finally launched on April 24\, 1990. While HST was not the first space telescope\, it represented a major expansion in capability that has helped upend humanity’s understanding of the universe. HST helped show that the expansion of the universe is accelerating\, and has transformed our view of the universe with a remarkable set of Hubble Deep Field images\, amongst other things. Along the way\, the engineers\, scientists and astronauts behind HST managed to overcome a debilitating optical problem and have kept HST making discoveries for more than three decades. Now HST is about to work in tandem with its successor\, the James Webb Telescope.\nNot Yet Imagined E-flyer\n\n \n\n \n\nChristopher Gainor is a historian of technology specializing in space exploration and aeronautics. He has written four books on the history of space exploration and two on Cold War history. His most recent book is a history of Hubble Space Telescope operations published by NASA. Gainor is editor of Quest: The History of Spaceflight Quarterly. From 2018 to 2020\, he was President of the Royal Astronomical Society of Canada\, and he is a fellow of the British Interplanetary Society. Gainor holds a Ph.D. in the history of technology from the University of Alberta\, and has worked as a history instructor at the University of Victoria and the Royal Military College of Canada.\n\n \nhttps://chrisgainor.ca\n \nhttps://www.facebook.com/Gainorbooks\n \nhttps://twitter.com/chrisgainor\nViews: 72
