WESTPORT — The Westport Astronomical Society will host Jilliam Bellovary, a physics professor at Queensborough Community College, as the next guest in its free lecture series

Bellovary will discuss gravitational waves and the ways scientists have learned to measure them. She’ll also speak about black holes, and the future of gravitational wave observations, including a space observatory that will teach scientists about how the biggest black holes in the universe grow.

Bellovary is an expert on the cosmic evolution of supermassive black holes, and a research scientist at the American Museum of Natural History. She currently serves on the Committee for the Status of Minorities in Astronomy and strives to increase inclusion and equity in the sciences.

This event will take place at 8 p.m. Jan. 16 at the Westport Astronomical Society, 182 Bayberry Lane, Westport. The event is free and open to the public. Registration is not required.
