SUMMARY:General Meeting – October 2025
DESCRIPTION: Join Zoom\n\nThis meeting’s speaker will present inperson from the Chapman campus.\n\n\n\n\n\n\n\n\nThe Search for Earth 2.0:\n  \nWhy We Think It Exists\, and\n  \nHow We’re Going To Find It\n  \n\n\n\n\n\n\n\n\n \n\n\n\n\n\n\n\n\nFor thousands of years\, we’ve wondered if the Earth is unique\, or if there are other Earths out there to find. In just the last 30 years\, we’ve progressed from merely wondering if planets exist around other stars to knowing that almost every star we see has planets. Ambitious planet searches have been probing further and further\, finding planetary systems of an incredible – and incredibly surprising! – variety. However\, we have yet to discover another planet that might be like Earth – a rocky planet orbiting just the right distance from a Sun-like star to have liquid water on its surface. NASA has a audacious new plan for a next-generation flagship telescope that will directly image Earth-like planets around nearby stars\, but it will take all of our ingenuity and technical prowess to achieve this incredible feat. Dr Christiansen will walk you through the past\, present\, and future of our hunt for Earth 2.0. \n \n\n\n\n\n\n\n\n\nDr. Jessie Christiansen is the Chief Scientist of the NASA Exoplanet Science Institute and a TED fellow. She has worked on NASA’s Kepler\, K2\, and TESS missions\, searching the sky for exoplanets\, and is helping plan for NASA’s next big flagship missions – the Nancy Grace Roman Space Telescope\, and the Habitable Worlds Observatory. Dr. Christiansen’s research is in the detection and characterization of exoplanets – planets around other stars – and studies of exoplanet populations\, and she is currently the most successful woman planet hunter in the world. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nViews: 2

SUMMARY:General Meeting – September 2025
DESCRIPTION: Join Zoom\n\nThis meeting’s speaker will present inperson from the Chapman campus.\nPathway to a\n  \nPost-Global Warming Future\n  \n— A Brief Overview of Climate Science\,\n  \nConsequences\, and Solutions\n  \n(and their astronomical connections!)\n  \n \n  \nGlobal warming may not seem obviously connected to astronomy — but it is. In fact\, the basic science of global warming is best understood through comparative study of planets. In this presentation\, astrophysicist/educator Jeffrey Bennett will give you a brief overview of the surprisingly simple basic science behind global warming (including its astronomical connections) and of the consequences we can expect from this warming. Most important\, he’ll focus on solutions and how we can in principle take the steps necessary to create a “post-global warming” future\, meaning a future in which today’s children will someday be able to talk about global warming as a once-serious problem that we found a way to solve. Note: This talk is based on Dr. Bennett’s book A Global Warming Primer — Pathway to a Post-Global Warming Future. \n \nAstrophysicist/educator Jeffrey Bennett has devoted his career to science education and outreach. He is probably best known to the astronomy community as the lead author of the widely used textbooks The Cosmic Perspective and Life in the Universe. He is also the author of textbooks in math and statistics; of several critically acclaimed books for educators and the public; and of 7 award-winning science books for children. He served two years as a visiting senior scientist at NASA headquarters\, proposed and co-led development of the Voyage Scale Model Solar System on the National Mall (Washington\, D.C.)\, created the free Totality app for learning about solar eclipses\, and created a free online textbook for middle school Earth and Space Science. Among other honors\, his children’s books were the first ever selected for Story Time From Space\, in which books are launched to the International Space Station and read aloud by astronauts\, and he has won both the American Institute of Physics Science Communication Award (2014) and the Klopsteg Memorial Award (2023) for education from the American Association of Physics Teachers. In addition to his ongoing speaking series on global warming\, his current projects include working to spread Voyage model solar systems across the country\, a planetarium show based on his book Max Goes to Mars\, and a new book on The Scale of the Universe to be published in January. \nViews: 2

SUMMARY:General Meeting – August 2025
DESCRIPTION: Join Zoom\n\nThis meeting’s speaker will present online from Topeka\, KS.\nExploding Stars and Life on Earth\n  \n \nScientists have long speculated that the history of life on Earth may have been influenced by cosmic explosions such as supernovae.  In recent decades the combination of astrophysical data and computational models have allowed detailed study of the potential effects of nearby stellar explosions on Earth’s atmosphere and biosphere.  Impacts range from destruction of stratospheric ozone\, exposing life to extreme levels of solar UV\, to direct damage to organisms by high-energy neutrons and muons.  This talk will summarize what is known today and discuss connections to mass extinctions and the evolution of life over the last few hundred million years. \n \nDr. Brian Thomas is a Professor in the Physics & Astronomy Department at Washburn University\, in Topeka\, Kansas.  Since 2003 he has worked on various problems related to understanding how the history of life on Earth may have been affected by high-energy astrophysical events such as gamma-ray bursts and supernovae.  He and collaborators from multiple disciplines have together produced some of the most detailed and state-of-the-art studies of the effects on Earth by nearby stellar explosions. \nViews: 2

SUMMARY:General Meeting – June 2025
DESCRIPTION: Join Zoom\n\nThis meeting’s speaker will present online from Los Angeles.\n  \nA Trip to the Center of Our Galaxy\n  \n \n  \nThe heart of the Milky Way is home to Sagittarius A*\, a supermassive black hole approximately four million times the mass of the Sun. Although it remains largely quiet today\, it is surrounded by a turbulent sea of gas\, dust\, and exotic objects that could one day trigger dramatic outbursts. This presentation delves into this extreme environment\, exploring the large-scale gas clouds and the closer-in structures that fuel the black hole. It examines how molecular hydrogen manages to survive intense ultraviolet radiation and introduces a newly identified class of enigmatic objects orbiting perilously close to Sagittarius A*. Observed over two decades with the Keck Observatory\, these objects may represent the remnants of stellar collisions or merged binaries\, offering valuable insights into how matter behaves under immense gravitational forces. Mapping this region helps to illuminate the intricate interplay of stars\, gas\, and gravity at the core of the galaxy. \n \nAnna Ciurlo’s research focuses on stars and gas around the supermassive black hole in the center of our Galaxy. Her work leverages high-resolution imaging and spectroscopy from large ground and space-based observatories like Keck and the JWST. She earned her PhD in astrophysics from the Sorbonne Paris Cité and pursued postdoctoral research at UCLA. She was an inaugural year Keck Visiting Scholar at Keck Observatory. Anna continues at UCLA as an assistant researcher and adjunct assistant professor in the Galactic Center Group. \nViews: 2

SUMMARY:General Meeting – May 2025
DESCRIPTION: Join Zoom\n\nThis meeting’s speaker will present live from Albany\, NY.\n  \nFast Radio Bursts-Signals\n  \nfrom Across the Universe\n  \nThis artist’s impression (not to scale) illustrates the path of the fast radio burst FRB 20220610A\, from the distant galaxy where it originated all the way to Earth\, in one of the Milky Way’s spiral arms. The source galaxy of FRB 20220610A\, pinned down thanks to ESO’s Very Large Telescope (VLT)\, appears to be located within a small group of interacting galaxies. It’s so far away its light took eight billion years to reach us\, making FRB 20220610A the most distant fast radio burst found to date. \nFast radio bursts (FRBs) are bright flashes of radio waves that last only a few milliseconds and are visible across the universe. Although approximately 10\,000 of these occur every day\, they were only discovered by accident in 2007. Their origins remain largely unknown\, making FRBs one of the hottest topics in radio astronomy. In this talk\, Dr. McKee will describe the discovery of FRBs\, what we know about them\, and what the next few years of radio astronomy holds for this exciting new field of astronomy. \nUnion College headshotsWednesday\, September 4\, 2024James McKee\, Union College\, Physics & Astronomy \nDr. McKee studied physics at the University of Hull\, and obtained a PhD in astronomy and astrophysics at the University of Manchester while working at Jodrell Bank Observatory. Dr. McKee has held research positions at the Max Planck Institute for Radio Astronomy\, where he was also the on-site pulsar astronomer at the Effelsberg radio telescope\, and at the Canadian Institute for Theoretical Astrophysics at the University of Toronto where he worked on the CHIME telescope. He is currently an assistant professor of physics and astronomy at Union College in NY\, where he leads research into pulsars and fast radio bursts. \nViews: 2
