Astronomy at the Winery

It’s September. Throughout the northern hemisphere the grape harvest is in full swing. The fall equinox marks the start of autumn, meaning cooler weather and shorter days.

But what is an equinox? Why is it in September? What does astronomy have to do with it?

Dr. Brian W. Mulligan will guide us through the history of calendars to learn

• What is a year, and how did we figure it out?
• How do solstices and equinoxes relate to the Earth’s orbit around the Sun?
• How have agriculture, war, religion, politics and astronomy influenced the development of our calendar?

Come join AoTATX for a relaxed evening, learning a little astronomy over a glass of wine.

Astronomy on Tap ATX (AoTATX) is held on the second or third Tuesday of every month at Celis Brewing at 8:00 pm during summer and 7:30 pm the rest of the year. AoTATX is currently organized by a committee of Austin-based astronomers.

AoTATX features accessible, engaging science presentations on topics ranging from planets to black holes to the beginning of the Universe. In addition to talks, each AoTATX has trivia, prize giveaways, Astronomy in the News and plenty of time to interact with the presenters and other astronomers in the audience. 

Find them on Facebook, Twitter/X and Instagram. Selected talks from previous events can be found on their YouTube channel.
