The stars are aligning at BAM later this month for Neil DeGrasse Tyson, astrophysicist and director of Hayden Planetarium, to host an episode of his weekly radio show StarTalk Live! at the Howard Gilman Opera House on Feb. 24–tickets go on sale this Wednesday. Tyson has covered everything from Gravity to Ghostbusters, sex to salt and the Big Bang Theory–both the scientific supposition and the TV show–since starting his talk show in 2010. Actress Mayim Bialik of TBBT (a neuroscientist on TV and in real life) is the special guest at this month’s taping, being co-hosted by comedian Eugene Mirman, with more guests to be announced in the coming weeks. Expect tickets to sell somewhere close to the speed of light for this show, so snag yours earlier if you want a seat.
