 Hydrogen Alpha: Unlocking the Sun's Chromosphere: a talk by Beth Tatum, NOVAC.
In this presentation, amateur astronomer and solar imager Beth Tatum will talk about safely observing and imaging the sun, particularly using specialized telescopes through which you can see the fascinating detail of the solar chromosphere. She will present a series of photographs taken with this equipment to show the different types of features one can observe, such as filaments, prominences, flares, and plage regions. She will also talk about simpler ways to safely observe the sun and the most apparent features of its surface, including sunspots.
Beth Tatum is a software QA engineer who lives in Ashburn, Virginia with her husband Ken and son Kevin. A lifelong amateur astronomer, she built her first telescope while in college, and has been a member of the Northern Virginia Astronomy Club for more than 10 years.
 Full-dome movie: STARS: the Powerhouses of the Universe.
Every star has a story. Some are as old as time, faint and almost forgotten. Others burn bright and end their lives in powerful explosions. New stars are created every day, born from vast clouds of gas and dust. Through every phase of their existence, stars release the energy that powers the Universe. Journey to the farthest reaches of our galaxy and experience the awesome beauty and destructive power of STARS. Running Time: 26 minutes.

“Life and Death: The Earth-Sun Connection”: a talk by Dr. Bethany Cobb Kung, George Washington University
The influence of the Sun on life on Earth is complex — without the Sun, life couldn’t exist and yet the Sun will eventually render the Earth uninhabitable. This talk considers the various connections between the Sun and the Earth — from solar energy, to coronal mass ejections that trigger aurora, to the ultimate fate of our solar system. Bring your active brains, as the talk will feature interactive elements.
Bethany Cobb Kung is an astronomer who received her Ph.D. at Yale University in 2008 for research on massive stellar explosions. She is currently an Assistant Professor of Honors and Physics at The George Washington University, where she studies gamma-ray bursts and teaches physics and astronomy primarily to non-science majors.
