1 – 2pm • Understanding the Atomic World: An Introduction to Spectroscopy
Astronomy is a unique science because we can't study distant objects in our laboratory here on Earth. The only information we get travels to us in the form of light. Astronomers must be experts on light! Ever wonder why you see certain colors, or how we know that stars are mostly hydrogen and helium, or how we measure the dynamics of distant galaxies? Come learn the basics of atomic physics and see the emission of light from different elements with your own eyes in a live spectroscopy demonstration.
Presented by Astronomy Professor Stephanie Cortes.
2:15 – 3:15pm • From our Sun to the Stars, a beginners guide to “Exist”
In this game-based, interactive presentation, audience members will engage in a series of activities to develop an understanding of what stars are, their formation process, their diverse properties, and their abundance in the universe. Be ready to interact with your fellow audience members and get your star game on.
Led by the University of Arizona’ Astronomy Honor Student Program
3:30 – 4:30pm • Life of Stars
A lay summary of the life of a star, from birth to the multitude of deaths various stars undergo. We will explore the life of a star much like our own, as well as the more exotic fates of larger stars. With the backdrop of the recent ground-breaking first images of a black hole, we will briefly touch on how some black holes are formed.
Presented by Dr. Aaron Farber.
Dr. Aaron Farber has looked longingly towards the skies for his entire life. Dreaming of being an astronaut as a child, he earned a BA in Astrophysics from Columbia University before moving out to Tucson for graduate school. During Aaron's undergraduate work, his research interests focused on cataclysmic variable stars and other more observational focused projects. He spent a semester living at the Biosphere 2 Center, and several weeks up on Kitt Peak running the 1.3 meter MDM telescope for his undergraduate advisor. Aaron fell in love with the desert, so when the call of graduate school rang, Tucson was an exciting opportunity. Interested in branching into the more engineering side of instrumentation, he earned his PhD in Aerospace Engineering, conducting research in the UA Nuclear Reactor Lab and working closely with the Optical Sciences department. His dissertation work on gamma ray imaging technology has been patented and he is still hoping to find the funding to actually build his design. Aaron is currently employed by L3 Latitude, which designs and builds hybrid unmanned aerial vehicles for scientific research, Government and civil customers. During any celestial events, he is often found dragging out his telescope and asking his neighbors to turn out their lights. Aaron is deeply grateful for the wonderful life he has with his amazing partner and Exist performer, Leanne, as well as his amazing 2 year old son, Jude.
