Astronomy 102: Stars, Galaxies, Cosmos

Zoom

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

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.

CLOCKS, CALENDARS, COORDINATES, ORBITS

Zoom

Wednesdays, 7 PM. March 30; April 6, 13; May 4, 11, 18

The measurements of time in hours, days, months, and years has astronomy roots. Historically, calendar dates were particularly complex to fix in all cultures because the Earth, moon, and sun have revolution rates that are not simple multiples. Objects in the sky and in space are assigned coordinates using different systems. These coordinates are vital to determining and specifying the motions and orbits of space objects. It takes six parameters to specify an orbit. We explore these themes.
