Astronomy on Tap ATX
Austin's new chapter of Astronomy on Tap has outgrown its venue, and moves to Scholz Garten, on Tuesday, January 20th. Astronomers Jeffrey Silverman, Eva Noyola, and Brian Mulligan will talk about latest discoveries from the American Astronomical Society's (AAS) meeting in Seattle, The Science and Science Fiction of Black Holes, and Astronomy in Time and Calendars. Questions previously submitted by pub goers for future discussion include, "Are any distant galaxies moving away at almost the speed of light?", and "Why does time move forward?" Astronomy on Tap has chapters in New York City, Columbus, OH, New Haven, CT, and Santiago, Chile.
