On line astronomy courses and descriptions

The courses in the astronomy sequence (PH 205, PH 206, PH 207) are stand-alone classes and can be taken in any order. There are no specific prerequisites or corequisites; students should have a working knowledge of basic algebra. An accompanying laboratory includes outdoor observations as well as analysis of observational data and virtual experiments to develop an understanding of making hypotheses, organizing and presenting data, analysis and model construction. This on line class is an accredited Bacc Core Course, fulfilling the requirement for a science class with a lab.

Kathryn Hadley PhD


I graduated with a PhD in Physics from the University of Oregon (UO) in 2011. While doing research in theoretical astrophysics, I taught astronomy at Lane Community College (LCC) where I received the Faculty Recognition Award. After graduation, I taught at Whitman College as a visiting professor for two years, and then at Lane Community College for two years. I am now full time at Oregon State University, teaching Astronomy courses in both fully on line and hybrid formats.

Physics 205

Solar System Astronomy

Our own solar system gives us the best opportunity for studying planets close-up. In this course, we study a variety of planets, including the terrestrial planets: Mercury, Venus, Mars and Earth, and Jovian planets: Jupiter, Saturn, Uranus and Neptune, and of course, minor planets like Pluto. We also discuss other members of the solar system such as comets and asteroids. We pay special attention to the discovery and understanding of extrasolar planets. These extrasolar planets have given us reason to rethink our theories regarding how our solar system was formed. In this class, we delve into solar system formation with an eye on including this new information.

Physics 206

Stars and Stellar Evolution

This course focuses on the formation, and evolution of sun-like stars and more massive stars. We will begin by studying light and how it gives us information regarding stars. We then look at our closest star, the sun, in detail, including how fusion produces energy in the core, and how that energy is transported to the surface of the sun. We learn about features of the sun like sunspots, flares and coronal mass ejections We will explore stars in general with special consideration given to the processes of star formation and evolution. We then discuss the end-state of sun-like stars, and for more massive stars, the supernova, paying attention compact objects like neutron stars and black holes.

Physics 207

Galaxies, Quasars and Cosmology

This course begins by examining our own galaxy, the Milky Way. We then look at galaxies in general, discerning between different kinds of galaxies and discussing galaxy formation and evolution, and the role that dark matter plays. We go on to consider the universe as a whole. We will look at the current state of the mapping of the universe and its large scale structure. We will then look at its creation, focusing on aspects of the big bang theory and observational evidence backing up our theory, namely, the cosmic microwave background radiation. We discuss the evolution of the universe to its present state, including the relatively recent discovery of the acceleration of the expansion of the universe and dark energy. We finish by studying life in the universe, including the possibilities of finding life on other planets and in other star systems.
