This weekend the Treasure Coast Astronomical Society will host Astronomy Day at Indian River State College. The College’s Planetarium will be open this Saturday – that’s tomorrow, March 4th - from 2 pm until 9 pm, and there will be meteorite displays, telescope clinics, and guest speakers, including a NASA spokesman, plus space activities for the kids. Bring your telescope to the telescope clinic and the Treasure Coast Astronomical Society will show you how to make it work! And when it gets dark that evening, we hope to provide telescopic views of the moon and the planets Venus and Mars, as well as a few stars and deep sky objects. This astronomy day event is free, no tickets are necessary. Just dress warm, bring a lounge chair for viewing the sky and come on out to the Hallstrom Planetarium and the IRSC Science Center at 30th Street and Virginia Avenue on the Fort Pierce campus.
