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.

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! šŸ‘½šŸ›øā˜„ļø

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 ā€œThe Scourge Between Starsā€ 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!

Thank you to everyone who signed up for this research study at Astronomy on Tap last Friday! We had a fantastic response and are excited to continue recruiting participants.

Interested in astronomy, science communication, podcasts, or how scientists connect with the public?

We're looking for participants for a CU Boulder research study exploring how listeners experience scientists in specific astronomy media.

Participation involves a one-time, in-person discussion session with a small group of fellow participants. No astronomy background is required—we're interested in your honest thoughts and reactions. Participants will receive compensation for their time.

Scan the QR code to learn more and sign up for the interest list. Filling out the form does not commit you to participating.

Please feel free to share with anyone who may be interested.

AoT Boulder’s June event is shaping up to be a truly out-of-this-world event, and we’re so excited to announce this month’s speakers! ā˜€ļø

Join us at 8pm on June 12th to hear about solar physics, planetary atmospheres, and exoplanet science from leading scientists!

Dr. Ryan French is a solar physicist, science communicator, and author, currently based at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder. He is pursuing the mysteries of the Sun at the forefront of modern solar physics research, using cutting edge telescopes on the ground and in space. Ryan also works to share the wonders of the Sun and space with the public, through his published popular astronomy books, social media, and public talks.
Fun fact: As if Astronomy wasn’t already nerdy enough, Ryan recently picked up a new hobby — bird watching!

Dr. Zach Berta-Thompson is a professor of astrophysical and planetary science at the University of Colorado Boulder. He uses telescopes to observe exoplanets, worlds orbiting other stars in the Milky Way Galaxy. Zach grew up as the son of two ceramic artists in Michigan, studied with caring astronomers at Princeton, Harvard, and MIT, and started as a professor at Colorado in 2016. At CU, he leads a team of researchers and teaches students to practice using curiosity, creativity, coding, and kindness to learn more about how worlds work.
Fun fact: Zach does a lot of baking wuth a four-year-old who often refuses to follow a recipe, resulting in the discovery of horrible and magnificent new treats.

Dr. Dave Brain is a Professor of Astrophysical and Planetary Sciences here at the University of Colorado. He uses spacecraft data and computer models to understand the atmospheres and magnetic environments of rocky planets such as Mars, Earth, and Venus.
Fun fact: Dave can balance things on his chin, including chairs!

We are excited to announce this month's speakers! Join us at Rosetta Hall
Saturday, March 21st - 8:00 PM
This event will also host representatives from Fiske Planetarium, KVCU Radio 1190, and the Open Orbit podcast. Learn more and speak with leading experts in science and communication!
Dr. Fran Bagenal is a senior research scientist and professor emerita at the University of Colorado, Boulder. She has participated in several of NASA's planetary exploration missions, including Voyager 1 and 2, Galileo, Deep Space 1, New Horizons and Juno. Her main area of expertise is the study of charged particles trapped in planetary magnetic fields and the interaction of plasmas with the atmospheres of planetary objects, particularly in the outer solar system.
Born and raised in the UK, Dr. Bagenal received her bachelor's degree in Physics and Geophysics from the University of Lancaster, England, and her doctorate degree in Earth and Planetary Sciences from MIT (Cambridge, Mass) in 1981. She spent five years as a postdoctoral researcher at Imperial College, London, before returning to the United States. In 1989, she joined the faculty at the University of Colorado in the Department of Astrophysical & Planetary Sciences.
She edited the monograph Jupiter: Planet, Satellites and Magnetosphere (Cambridge University Press, 2004). She has given many talks at schools and public events on the exploration of the outer solar system. In 2015, after 26 years of teaching, she gave up her faculty position to focus on New Horizons reaching Pluto and Juno in orbit around Jupiter.
Fun fact: Over the past 20 years, Fran has drunk about 10 cubic yards or meters of coffee at the . That would take 3 pick-up trucks to load up!
Sean McElwee graduated from UMass Amherst in 2014 with a BS in Astronomy. Out of undergrad, he began his career in photonics working at Thorlabs. Initially starting as an Application Engineer in their Tech Support department, he has been at Thorlabs for 12 years and currently works as a Content Strategist developing educational animated short form content.
