Dr. Robin ElgartSpace Radiation: Health Risks to the Astronaut Corps. “Danger, Will Robinson!” Scientists as well as astronauts have discovered that space really is dangerous. It’s not the ride into space—rockets are pretty reliable now. And it’s not meteors shooting through space, either. It’s just being there, sitting around on a space station, that might be the most dangerous. It’s the radiation that can kill you, give you heart disease, or even cancer years later. This presentation by Dr. Robin Elgart, the Space Radiation Element Scientist in NASA’s Human Research Program at the Johnson Space Center, provides a brief description of the space radiation environment, as well as a summary of a study assessing excess cardiovascular disease or cancer mortality in early NASA astronauts. © 2022

Dr. Alexandra YepMeteors, Meteorites, MeteoroidsOh My! Meteors streaking through the sky are beautiful and mysterious. Have you ever wondered about the types, origins or compositions of meteors? Dr. Alexandra Yep explores their origins, appearances and compositions in this fun and informative presentation. She shares with us when we might next see a meteor, and where we might find meteorites. Dr. Yep is a poet turned astronomer. After earning her BFA in creative writing and classical studies, she dove straight into quantum mechanics on her way to a Ph.D. in astronomy. Now a professor at Agnes Scott University in Atlanta, Georgia, she researches stars and star clusters. © 2022

Carl HergenrotherObserving Comets and the Association of Lunar and Planetary Observers. Carl has discovered four comets and a more than a dozen asteroids. Some of the more interesting comets discovered in recent years are presented in this lecture as well as the science contributed by observers with modest backyard equipment. Carl Hergenrother is the Executive Director of the Comets Section of the Association of Lunar and Planetary Observers (ALPO). He has pent most of the past decade working on NASA’s OSIRIS-REx mission to retrieve samples from near-Earth asteroid Bennu. His two primary contributions to OSIRIS-REx were the selection of Bennu as the target and the novel and surprising discovery that Bennu is routinely ejecting small particles of itself into space. He has since moved on to Ascending Node Technologies, LLC, a small business developing spacecraft planning and operations software. © 2022

Dr. Lynn CominskySpacetime Symphony: Gravitational Waves and Black Holes. Dr. Cominsky provides an introduction to gravitational waves, black holes and the Laser Interferometer Gravitational-wave Observatory (LIGO) . She also presents the gravitational wave detection results reported to date from LIGO and Virgo (another gravitational wave interferometer). On September 14, 2015, LIGO received the first confirmed gravitational wave signals. This event represents the coalescence of two distant black holes that were previously in mutual orbit. LIGO’s exciting discovery provides direct evidence of what is arguably the last major unconfirmed prediction of Einstein’s General Theory of Relativity. Dr. Lynn Cominsky grew up in the snows of Buffalo, New York, and attended college at Brandeis University, where she studied Chemistry and Physics. She then worked at the Harvard-Smithsonian Center for Astrophysics. When she found out that she could get paid for studying black holes, she went to graduate school in physics at MIT. After getting her PhD there in 1981, she moved to California. She has been on the faculty at Sonoma State University for over 35 years, and chaired the Department of Physics and Astronomy for 15 years. © 2021

Dr. Darren WilliamsProbing the Earth from Astronomical Distances. This presentation asks the question, “What would Earth look like to someone light years away? Would it be a featureless blue dot, or could we possibly see oceans, snow and ice, forests, or even cities through the clouds?” The answer to this question is what astronomers are considering as they collect and interpret the light from distant exoplanets. They are too far and too faint to “see” with advanced telescopes but futuristic telescopes may be able to determine their sizes, spin properties, and atmospheric compositions. Dr. Darren Williams, as a teen, started his future career as an astronomy hobbyist right here at the Martz-Kohl Observatory. In addition to teaching, he studies the climates, orbits, observable characteristics, and dynamical evolution of planets and satellites. His current focus is on the final stages of planet formation, and designs for a new miniature space telescope (The Pale-Blue-Dot Telescope) to remotely observe terrestrial planets at sub-pixel resolution. © 2021

Daniel KrysakExploring Mars and Jupiter: the Mars Curiosity Rover and Juno Missions. Daniel is a real Martian, or as close to one as a man can get on Earth. This webinar provides a fun, in-depth look at the various cameras on board both the Mars Science Laboratory (MSL) Curiosity rover on the red planet, and the Juno spacecraft mission to Jupiter. Daniel shows a fascinating gallery of images acquired by both spacecraft throughout their missions. Daniel Krysak grew up in New York State. He graduated from SUNY Potsdam with degrees in both speech communication and archaeology in 2008. He went on to earn a Masters degree in Planetary Volcanology from the University at Buffalo in 2011. Daniel started working at his current company, Malin Space Science Systems, in early 2012 as part of the MSL Curiosity rover operations team. In 2015, he went further into the solar system by working camera operations on the Juno mission to Jupiter. © 2021

Dolores Hill, Dr. Patrick Miller and Carl HergenrotherTarget NEOs! Searching for and Characterizing Asteroids via Citizen Science. Citizen scientists have always played an important role in astronomy. By capturing images of known asteroids over a long time period, amateur astronomers, students and the public can contribute to the characterization (physical understanding of asteroids) with Target NEOs! and other citizen science programs. Near-Earth Objects (NEOs) include asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighborhood. Amateur astronomers and astronomy organizations such as the Martz-Kohl Observatory, have access to research grade instrumentation and have the ability to devote time making observations that can fill in the gaps for professional astronomers who often are able to observe only a few asteroids a few nights per year. Dolores Hill and Carl Hergenrother are co-coordinators of the Astronomical League’s Target NEO Observing Program and Dr. Patrick Miller is Director of the International Astronomical Search Collaboration. © 2021

Alexandra YepYoung Stars Amid External Radiation and Colliding Associations. Ms.Yep is a poet turned astronomer. She first shared her research of The Gum Nebula and young stars as part of The Martz-Kohl Observatory Lecture Series in October, 2020. The observatory was honored to host her Ph.D. dissertation defense on 07 July 2021. As part of her work, she discovered several star clusters in the Gum Nebula which are now known as Yep-1, Yep-2 and Yep-3 and is only the second woman to have earned this naming honor. She also deduced that two distinct stellar associations are in the process of colliding. While her dissertation is about 250 pages of detailed mathematics, observations, charts and simulations, Ms. Yep managed to condense the highlights into an hour presentation. © 2021 Alexandra Yep

Ted WolfeArmchair Stargazing: Remote Astro Imaging in Chile. Ted returned to the Martz-Kohl Observatory this year, in person, with an exciting video tour prepared in collaboration with National Geographic Magazine as well as some of his latest astro images. The videos focused on a trip to his observatory in the Atacama Desert in northern Chile which he can operate remotely from anywhere in the world. But as always, Ted’s ultimate goal is the heavens. His spectacular images of deep space take viewers along to explore the whole universe without ever leaving our planet. He has been an astrophotographer since 1998, when he constructed one of the first remote, robotic, amateur observatories in southern Florida. Ted and his wife Nancy spend winters in Florida and summers at the Chautauqua Institution, here in Western New York. © 2021
