Astronomy on Tap brings lectures on the latest in space and planets and galaxies the way you want to hear them - at your favorite bar with a beer in your hand! Professional astronomers present engaging talks about their own research or recent discoveries in astronomy in a casual, fun atmosphere, often featuring games, trivia contests, and prizes. Audience participation and interaction is an important part of Astronomy on Tap - bring your curiosity and questions (and maybe we'll bring Neil deGrasse Tyson's trash to win!). Astronomy on Tap at STEMFest will be presented by astronomer Demitri Muna.

Started in 2013, Astronomy on Tap has expanded to over 15 locations around the world. Proceeds from ticket sales at STEMFest will support Astronomy on Tap’s free events in NYC and their contributions to local classrooms via


Iva Momcheva: Hubble's Evolving Universe
Iva Momcheva received her BS in physics from Sofia University in Bulgaria and her PhD in astronomy from University of Arizona, Tucson. Following research positions at Carnegie Observatories and Yale University, she is now a scientist at the Space Telescope Science Institute in Baltimore. In her current position, she is responsible for making sure the Hubble Space Telescope continues to produce its beautiful and scientifically important images with the Wide Field Camera 3 instrument. In her research, she works on understanding how distant galaxies evolve. Iva recently had an asteroid named after her: 8260 Momcheva. She will talk about what we have learned about the distant universe with Hubble and what more we expect to find out with its successor - the James Webb Space Telescope.

Guangtun Zhu: All the Things We Cannot See
Guangtun Zgu received his Ph.D. in physics at NYU and had a Hubble Fellowship at Johns Hopkins University. His research focuses on galaxy formation, the distribution of matter (dark and ordinary), the large-scale structures of the Universe, and data-intensive astronomy. He will talk about the distribution of dark and ordinary matter, what we have learned about the universe from the limited data we have collected with incredible human intelligence and creativity. He will pay tribute to the late Vera Rubin, and how she discovered a phenomenon that no standard theory can yet explain (and why she should have been awarded a Nobel prize).
