Astronomy on Tap presents our September speakers!

Sarah Bruce is a 5th year PhD candidate in Astrophysics at CU Boulder and full-time eclipse enthusiast. She does her thesis research at the National Solar Observatory studying the temperature & heating of the solar atmosphere during eclipses. She has helped develop multiple solar observation instruments at the Harvard-Smithsonian Center for Astrophysics. Prior to her PhD, she got her BS in Math at UT Austin and did research in experimental geometry and astrostatistics.

Amelia Gandhi is a first-year PhD student in the Astrophysical and Planetary Sciences department at the University of Colorado Boulder. Originally from South Carolina, she recently graduated from the University of Colorado Boulder with degrees in Astrophysical and Planetary Sciences and Geology. In her PhD, she hopes to explore one main question: how does a planet’s magnetic field affect how its surface and atmosphere evolve over time? Her past research includes analyzing movies of aurora on Mars and mapping subsurface fabrics underneath volcanoes in the Alaskan Aleutian Arc. She hopes to continue exploring the connection between planetary magnetic fields, the atmosphere, and habitability by modeling whether the Earth could have transported water to the Moon at a time when both worlds had global magnetic fields. Outside of research, you can occasionally find her at Rocky Mountain National Park, as she volunteers at astronomy events there during the summer.

Catch these amazing speakers at 8:00 PM Friday, September 25th at Rosetta Hall. Come wearing your greatest costume and enter our costume contest!!

As AoT Boulder shifts to bi-monthly events (every other month) this year, we invite our audience to attend many other immersive ways to interact with space and the people involved in studying it. In lieu of an August AoT Boulder event, we highlight a special opportunity to engage with space at Little Thompson Observatory in Berthoud, Colorado.

The Little Thompson Observatory hosts free monthly star nights, offering presentations from scientists and the opportunity to look through their incredible telescopes. Catch AoT Boulder lead organizer, Hunter Pratt, giving a presentation at 7:30 PM, Friday, August 21st at Little Thompson Observatory and stick around to look at real objects in space with your own eyes.

Some of the best opportunities begin with a conversation. Join us tonight to network with astronomers, science communicators, educators, and fellow space enthusiasts. Whether you're curious about astronomy, looking to get involved, or just want to meet great people, we'd love to see you there.

Calling all Boulder astronomers, especially science fiction lovers! Have you ever wondered why talking with aliens is currently reserved for the fictional world, or whether there’s a real scientific basis to your favorite sci-fi horror story? If you answered yes to either question, July’s Astronomy on Tap Boulder event is one you won’t want to miss! We’ll see you at 8pm at Rosetta Hall on July 17th to hear from our wonderful speakers, Vanessa Brown and Simone Williams! 👽🛸☄️

Vanessa Brown is an author by day and astrophysicist by night. They are a PhD candidate in Astrophysical and Planetary Scoences at the University of Colorado Boulder and former college astronomy lecturer, writing speculative fiction while studying early epochs in cosmic history. Their novella “The Scourge Between Stars” was their science fiction horror debut, and they also write for the Warhammer 40,000 universe. When not writing or researching, they laze around with their husband and two cats, Faust and Mephi.
Fun fact: Vanessa has trained for over a decade in Wing Chin kung fu and Tai Chi.

Simone Williams is an astrophysicist, science communicator, and park ranger passionate about making science engaging and accessible. She graduated from Yale University with a B.S. in Astrophysics and has worked with the National Park Service, NASA, and other science-focused organizations to connect people with astronomy. When she’s not sharing the wonders of the universe, Simone enjoys rock climbing, traveling, and exploring the outdoors.
Fun fact: Simone can recite from memory all the countries of the world, as they were in the 1993 Animaniacs song!
