Astronomy 102: Stars, Galaxies, Cosmos


Thursdays, 7:30-9:30 PM. Feb. 10, 17, 24; March 3, 10, 17, 2022.  Online via Zoom.
Registration is now closed.

Astronomy 102 explores the universe beyond the Solar System. We discuss how and when the universe began, the formation of stars and galaxies, its expansion, and probable future.  We study how astronomers measure great distances and how stars generate their tremendous energies.  We will explore how elements are produced in stars, the structure and types of galaxies, and exotic objects like neutron stars and black holes.
