Astronomy

The astronomy program has classes that cover everything from our nearest celestial neighbors to the edge of the observable universe. Astronomy courses explore the ways planets, stars, galaxies, and the entire universe evolve and the science of looking for life beyond our Earth. Astronomical questions range from the deeply philosophical (what is the fate of the universe) to the immediately practical (how are humans impacting the Earth's climate). 
Courses in astronomy satisfy general education requirements for the associate degree and lower division transfer. There is one astronomy course in the honors program, ASTR 115H Planetary Astronomy - Honors.

This discipline prepares students to do the following:

  • Describe astronomical events and process to peers.
  • Estimate and/or calculate the characteristics of astronomical objects, and understand the meaning of these calculations.
  • Apply an understanding of relevant astronomical process as well as processes from related sciences (e.g. physics, geology, chemistry) to astronomical questions.
  • Understand the size and scale of the universe.
