Last week we heard from Jay Miller, a longtime member of the National Capital Astronomers, who gave an entertaining talk on our universe and various theories about its history.

Serving Science and society since 1937, the National Capital Astronomers (NCA) is a non-profit, membership-supported, volunteer-run, public service corporation dedicated to advancing space technology, astronomy, and related sciences through information, participation, and inspiration, via research, lectures and presentations, publications, expeditions, tours, public interpretation, and education. NCA is the astronomy affiliate of the Washington Academy of Sciences.

The National Capital Astronomers offers a popular program for exploring the sky in Rock Creek Park on a Saturday night from April through November. The event is free and welcomes beginners and experienced stargazers. For more information, visit www.capitalastronomers.org.
