Science

Astronomy on Tap. Learning about the cosmos and all manner of out-of-this-world subjects has never been so fun and accessible. August’s talk brings a new round of topics: how the most massive galaxies in the universe are discovered with the use of large surveys, what the relevance is of exploding stars and a recent exciting discovery made by the Rosetta Mission, which was orbiting around a comet. Weather permitting, there will be telescopes available to look for exciting sights in the night sky. 7:30 p.m. Aug. 21. Free. The North Door, 502 Brushy St. facebook.com/events/724189277930948/.
