Our exploration of the Earth, Solar System, and Universe continues. As always, we will discuss ongoing discoveries in astronomy, planetary sciences, and Earth sciences. Information will be conveyed using short videos, awesome photos, understandable/fun graphics, and class discussions. We will have several guest speakers from the University of Arizona's Astronomy, Planetary Sciences, and Geosciences Departments. Science Fiction Theatre continues, with short clips highlighting a century of sci fi movies and TV shows. And of course, there will be Geo-feature of the Week, What's for Launch?, and Books of the Week. Please join us for this continuing journey of discovery and adventure. Being in an earlier Astronomy/Geosciences class is neither a prerequisite nor necessary to understand and enjoy this class.
This term our key topic will be the Cosmological Toolkit. This Toolkit will include such concepts/theories/laws/insights as the Eddington and Roche limits, Redshift, Cosmic Distances, Kepler Laws, the Hertzsprung-Russell diagram, Stellar Magnitudes, Lagrange Points, and the EM spectrum, to name a few.
This is an OLLI at University of Arizona class. Arizona does not observe Daylight Saving Time. After March 9, 2025, this class will begin at 1pm Pacific time.
This class from OLLI at the University of Arizona will be recorded. OLLI-UA recordings can take up to a week after the class meeting to become available.
