Astronomy on Tap. Learning about the cosmos and all manner of out-of-this-world subjects has never been so fun and accessible. October’s talk, featuring three knowledgeable astronomers, brings a new round of topics, such as why statistics matter in the study of star formation and what exploanets are. The monthly event will also have astronomy news, trivia and telescopes so you can explore the starry night (weather permitting, of course). 7:30 p.m. Tuesday. The North Door, 502 Brushy Drive. astronomyontap.org.

Music

Sure Sure, Wilderado at Barracuda. We caught rootsy pop band Wilderado last year opening for Buckingham McVie at Bass Concert Hall and were impressed by their melodic songcraft. A part of the ACL Fest bill this year, they’re sticking around for a few days afterward for this club show. It seems like a good match with headliner Sure Sure, a Los Angeles indie-pop band whose self-titled debut album came out in January. 7 p.m. doors Oct. 16. $15. 611 E. Seventh St. barracudaaustin.com. — Peter Blackstock

Theater & dance

"Matawan." In the summer of 1916, a series of fatal shark attacks terrorized the New Jersey Shore. Farther inland, a polio epidemic plagued Philadelphia, and looming over the entire nation was the dark cloud of World War I. In "Matawan," as performed by the UT's Department of Theatre and Dance, these are the challenges characters slow to change must face. The Dan Caffrey play spans several cities, the infinite depths of the ocean and the point of view of the shark, examining how our internal anxieties are often just as terrifying as national catastrophes. 7:30 p.m. Oct. 10-12, 16-20, 2 p.m. Oct. 14, 20-21. $15-$26. Oscar G. Brockett Theatre, 300 E. 23rd St. theatredance.utexas.edu/event/matawan.

Children are invited to join the action to help create magical moments. Opens Oct. 16. 10 a.m. and noon Tuesday and Thursday, 2 p.m. Sunday through April 21. $14-$16. 202 S.
