BSU Department of Physics Invites You to Join the First Friday Astronomy. First Friday Astronomy is open to the public and happens every first Friday (even in the summer months). Due to the Solar Eclipse, April's first Friday will be held on the second Friday. Lectures start at 7:30 pm (MT) in the Education Building, room 112, with stargazing to follow (weather permitting). Events are open to the public and donation-supported. You can donate at boi.st/AstroGive and live-stream at boi.st/astrobroncoslive.
