Hosted by Chief Astronomer at The Franklin Institute, Derrick Pitts, the Joel N. Bloom Observatory is open late to the public and offers 5 different telescopes for you to view celestial objects in the sky, including stars, planets, nebulae, and if conditions are right, a galaxy or two. The evening includes a Fels Planetarium show and a lecture or presentation (appropriate for ages 8 and up) on an astronomical or space science topic. The Observatory is staffed with knowledgeable observers and free star maps are provided. Meet some BIG STARS on the second Thursday of each month at The Franklin Institute!
