This past Friday (Sep 17) we held an exciting lecture by Professor Janna Levin. She explained the amazing consequences of merging black holes as dictated by General Relativity. The disruptions in spacetime generated by these encounters produce a bizarre kind of music that we may finally tune into with the next generation of gravitational wave detectors.
Following the lecture, most of the audience headed up to the roof of Pupin to take in the beautifully clear evening sky. While volunteers offered the usual celestial close-up views through three telescopes (showing the Moon, Jupiter, Uranus, and the Double Cluster), Josh gave tours of the newly visible Autumn constellations, and down in the lecture hall three more volunteers narrated a remote observing session with a telescope in the Canary Islands.
By all accounts it was a great start to our new season of Friday night events.
