Dr. Alexandra Yep – The Study of Stars. Stars come in all shapes and sizes: Big powerful blue stars, small yet feisty red stars, strange pulsating yellow stars, and more. How do we know so much about stars? How did we go from seeing tiny points of light in the sky to knowing about red giants and supernovae? In this talk, intended for a general audience, Dr. Alexandra Yep helps us learn all about stars and the tools astronomers use to understand them. Alex Yep is a poet turned astronomer. She now works as a visiting professor at Agnes Scott College in Decatur, GA, where she teaches physics and astronomy, researches young star clusters, and directs the Bradley Observatory.  © 2024

Walt Pickut & Tom Traub – The Onslaught of Extraterrestrial Objects. There has been a lot of activity in our solar system with solar flares and visits of Near Earth Objects (NEOs). Observatory board members, Walt Pickut and Tom Traub joined forces to talk about these recent events in the context of Earth being a “target.” Sunspot activity has produced flares and storms generating spectacular auroras as well as causing partial radio disruptions around the world. Tom Traub discusses the Sun, recent solar events and possible implications. NEOs such as comets, asteroids, and meteors are objects that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighborhood. Walt talks about the different types of NEOs, where they come from, how they’ve impacted the Earth, and possible future dangers.  © 2024

Mike Stafford – The Secret Life of the Sun: An Introduction to Solar Physics. The Sun is a marvel of physics. At its core, under immense pressure and scorching temperatures, hydrogen atoms undergo nuclear fusion releasing a tremendous amount of energy. This energy slowly makes its way outward, battling its way through layers of hot plasma, before radiating out into space as light and heat. The Sun’s influence extends far beyond its visible surface. Solar winds, a stream of charged particles, whip out from the Sun impacting Earth. Powerful corona mass ejections can disrupt satellites and power grids here on Earth. Semi-retired physics professor, Mike Stafford, returned to the Martz-Kohl Observatory to help us understand solar physics in a non-mathematical way while sharing the wonder that is our closest star.  © 2024

Walt Pickut – Are We Really Alone? The Search Has Only Begun! The search for extraterrestrial intelligence (SETI) is ongoing. The SETI Institute remains active in the field, using powerful telescopes and managing various projects. Unidentified Flying Objects (UFOs) are no more; we now have Unidentified Anomalous Phenomena (UAP). Walt Pickut discusses the latest Pentagon report on UAP, published in January 2024, as well as some take-aways from a public meeting held by NASA, last year. He also leads the audience in assigning values to the Drake Equation, a framework for considering the factors that might influence the possibility of extraterrestrial life. Walt Pickut is a scientific author and the author of the true-story, “The First Counterspy.” He is the perfect person to present recent factual findings, as well as a bit of speculation. Walt says, “the answer is still out there!” © 2024

Dr. John Mather – Opening the Infrared Treasure Chest with the James Webb Space Telescope. Nobel Prize Winner in Physics, Dr. John C. Mather, shows how the James Webb Space Telescope (JWST) was built, what we have found, and what we hope to find. JWST was commissioned in July 2022. With its cameras and spectrometers, JWST is already producing magnificent images of galaxies, active galactic nuclei, star-forming regions, and planets. Scientists are hunting for some of the first objects that formed after the Big Bang, the first black holes (primordial or formed in galaxies), and beginning to observe the growth of galaxies, the formation of stars and planetary systems, and individual exoplanets. Dr. Mather is a Senior Astrophysicist and the Senior Project Scientist Emeritus for the JWST at NASA’s Goddard Space Flight Center. © 2024

Steve Conard – Occultation Timing to Determine Asteroid Size & Shape. What is an occultation and how does it help to obtain information about an asteroid? A stellar occultation occurs when the light from a star is blocked by an intervening body (such as a planet, moon, or asteroid) from reaching an observer. Steve Conard describes how amateur astronomers use modest sized telescopes and relatively inexpensive cameras to collect occultation data, along with software tools to predict events and analyze the resulting data. Steve has been an amateur astronomer for more than 50 years. His love of telescope making as a teenager turned into a 40 year career working for the Johns Hopkins University developing optical systems as an optical engineer.  © 2023

Dr. Alexandra Yep – Cosmic Collisions: Close Encounters in the Gum Nebula. When stars pass very close to each other, they potentially kick up comets from each other’s Oort clouds and cause heavy bombardment events. A stellar association is a very loose cluster of stars that share a common origin, but have become gravitationally unbound. A collision of stellar associations can serve as a laboratory of close stellar encounters. Dr. Alexandra Yep returns to the observatory to discuss the collision of two stellar associations in the Gum Nebula in the southern sky. A fun fact is that Dr. Yep is a poet turned astronomer – and we coaxed her to share some of her poetry.  © 2023

Gary Nelson – Binoculars and Telescopes: Types and Choices. What are some of the different types of binoculars and telescopes? What do all the numbers on binoculars and telescopes mean?
