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 – 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

SUMMARY:Online General Meeting - May 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n  \n\nOumuamua: The nearest exoplanet?\n\n  \n  \n\n \n\n\n\n\n\n\nWhen ‘Oumuamua passed by Earth in October 2017\, the only thing certain about it was that it was not from this Solar System. Because of its high velocity\, it was the first confirmed interstellar object. The next year the object 2I/Borisov was the second confirmed interstellar object. But whereas Borisov behaved very much like a comet (albeit an unusual one)\, mysteries remain about what ‘Oumuamua actually is. Although it pushed away from the Sun by a rocket effect\, like comets\, it could not be made of water\, or contain much carbon monoxide or dust\, making it very unlike a comet. The acceleration it experienced was very large\, and from the variations in sunlight it reflected\, it was more elongated than any other solar system object: either a very skinny pancake or a very long cigar. Dozens of explanations have been proposed to explain these oddities\, and speculation has run rampant\, with some astronomers even suggesting it was alien technology. The truth is more mundane but no less exciting. In a pair of papers in 2021\, Steve Desch and Alan Jackson demonstrated that ‘Oumuamua is consistent in every way with being a small fragment resembling the surface of Pluto. Our own solar system must have ejected trillions of fragments like ‘Oumuamua in its early days\, and a population of fragments from the surfaces of Pluto-like exoplanets must be common throughout the Galaxy. ‘Oumuamua itself may have been ejected about 400 million years ago\, from a Pluto-like exoplanet in a young system in the Perseus arm of the Galaxy. ‘Oumuamua is arguably the closest we’ve ever come to directly observing the surface of an exoplanet.\n\n\n\n\n\n\n\n\nSteve Desch is a Professor of astrophysics in the School of Earth and Space Exploration at Arizona State University. He studies the formation and evolution of planets\, the origins of the Solar System\, exoplanets\, and meteorites. He has written about ‘Oumuamua in the popular press and is thrilled to have contributed to our scientific understanding of this unique object.” \n\n\nhttps://slate.com/technology/2019/01/oumuamua-alien-ship-anthropomorphize-space.html\n\n\nViews: 72

SUMMARY:Online General Meeting - April 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n  \n\nThe End of the Beginning\n  \n\n\n\n\n\nWe used to think the Big Bang meant the universe began from a singularity. Nearly 100 years later\, we’re not so sure. The Big Bang teaches us that our expanding\, cooling universe used to be younger\, denser\, and hotter in the past. However\, extrapolating all the way back to a singularity leads to predictions that disagree with what we observe. Instead\, cosmic inflation preceded and set up the Big Bang\, changing our cosmic origin story forever.\n\nDownload PDF of the presentation\n\n\n\n\n\n\n\nEthan has lived his life fascinated with one simple fact: we have the capacity to figure out definitive\, scientific answers to even the deepest questions we can conceive about our physical reality. We do that by asking the right questions about the Universe\, and then putting the Universe itself to the test. From where everything comes from to the Universe’s ultimate fate and all that lies between\, he’s committed to not just figuring it out\, but to sharing the answers — what we know and how we know it — with anyone curious enough to listen.\n\n\nhttps://www.startswithabang.com/\n\n\nhttps://twitter.com/StartsWithABang\nhttps://www.facebook.com/startswithabang\n\nViews: 72

SUMMARY:Online General Meeting - March 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n  \n\nBringing Astronomy Alive:\n\n\n  \n\nStudent Engagement at\n\n\n  \n\n\nJohn Abbott College\n  \n\n\n\n\n\n\n\nThe non-traditional approach to Introductory Astronomy at John Abbott College (Montreal\, Canada) puts the depth and direction of content in the hands of the students\, utilizing partnerships with RASC Montreal Centre and other Outreach Organizations to mentor students in observational techniques\, provide access to amateur and professional Astronomical data\, and introduce students to public outreach.\n\n\n\nRecognizing the available access to recent discoveries and current data that best represent the direction of space sciences\, each student is given an opportunity to put their stamp on the learning outcomes of the course. Combining this with non-compulsory astronomy activities with RASC – Montreal Centre allows students to embrace the field in a manner that best suits their interests and motivation\, resulting in novel labs and incredibly diverse term projects\, and several initiatives that have moved beyond the scope of the Introductory Astronomy Course. Other departments and courses at the college are now taking advantage of the Astronomy activities to engage their students beyond the classroom.\n\n\n\n\n\n\nProf. Karim Jaffer joined the Physics Faculty at John Abbott College (JAC) in 2006\, with active projects in STEM education and pedagogical development. When Karim began teaching Introductory Astronomy in 2016 he developed a unique student-directed\, just-in-time teaching approach incorporating current astronomical data\, research\, and including experiential learning opportunities.\n\n\n\n\n\n\n\nIn the amateur astronomy community Karim has been the Public Events Coordinator for the RASC Montreal Centre since 2016\, helping re-establish the I.K.Williamson Astronomy Library and coordinating both public events and outreach activities throughout the Montreal area\, cultivating partnerships with the Rio Tinto Alcan Planetarium\, the Institute for Research on Exoplanets (iREx)\, the Cosmodome\, Explore Alliance\, the Astronomical League\, AstroRadio\, CASCA and many local amateur astronomy groups\, in addition to mentoring several Student Astronomy clubs and coordinating visits to local schools\, guides\, scouts and libraries.\n\n\n\n\n\n\n\nKarim is a member of the National RASC Education and Public Outreach Committee and the 2021 recipient of the Charles M Good Award.\n\n\n\n\n\n\n\n\nwww.rascmontreal.org/titan\n\n\n\n\n\n\nViews: 72
