In the ongoing lecture series (http://aaa.org/lectures1213) sponsored by the Amateur Astronomers Association (http://www.aaa.org/), there will be a free astronomy lecture at the American Museum of Natural History (http://www.amnh.org/). The lecture will be presented by Shane L. Larson of Utah State University, and the title of the lecture is "Whispers from the Cosmos: the Dawn of Gravitational Wave Astronomy".
Gravitational wave astronomy is a fascinating subject, and this event should be of interest to anyone with a love of science. And it is free! :-)
