Allegheny Observatory hosts a public lecture the third Friday of each month except for December.

This month, on March 21, “The Higgs Boson: a story of broken marriages” will be presented by Ayres Freitas, Department of Physics and Astronomy at the University of Pittsburgh.

On April 18, “How Do You Discover a Fundamental Particle?” will be presented by Jim Mueller, Department of Physics and Astronomy at the University of Pittsburgh.

Lectures begin at 7:30 p.m. and light refreshments will be available beginning at 7 p.m. A tour of the Observatory will be conducted following the lecture, and if the sky is clear an observing session with the historic 13-inch Fitz-Clark Refractor will follow the tour. More information can be found on the Observatory’s website.

Admission is free, but requires a reservation due to limited seating. For reservations, please call Lou Coban at the Observatory, 412-321-2400.
