Cosmos, constellations—and contemporary art! It’s last call at The Franklin Institute and you’re invited to a Star Party After Party, a late evening of science and dancing. This exclusive adults-only after party serves as round two of the Festival’s signature launch event, Citywide Star Party.




Sean Hearn - Most notable for producing the futuristic, spaced-out, synth driven party "Night Drive" at The Barbary in Fishtown, Sean will bring his eclectic mix of new and classic sounds; drawn from his passion and love for music across all genres and time periods, to the one and only Fels Planetarium.

Keegan Tewa - A Jazz saxophonist, Tawa combines a powerful and eclectic blend of original songwriting, focused production, real-time analog synthesis and aggressive, live saxophony. He’ll be delivering an even more unique, engaging and unforgettable performance through our silent disco in our Education Center on the 1st Floor.
