See the center of the galaxy from Westport: NASA telescope images of Milky Way

A post-doctoral fellow in astronomy and astrophysics will talk Tuesday about X-rays and gamma rays emanating from the center of the Milky Way at a meeting of the Westport Astronomical Society.

The meeting is planned at 8 p.m. at the Rolnick Observatory, 182 Bayberry Lane, and is free and open to the public.

The presentation by Kerstin Perez, a National Science Foundation fellow at Columbia University, is scheduled at 8:30.

The first high-resolution images of high-energy emissions from the center of the galaxy were captured by the NASA's NuSTAR telescope, launched in 2012, the astronomical society said in a news release. Perez will discuss the images and extreme gravitational and magnetic fields at the galactic center that cause violent acceleration and radiation processes.

The images have implications on diverse topics, including previously undetected black holes, the group said.
