In this, the final lecture of the semester, I attempt to review the main, salient points of the course. Whew! Quite a whirlwind!
In this, the LAST lecture of the semester, we discuss General Relativity and Black Holes.
In this lecture we discuss the final stages of the evolution of low and high mass stars. We also learn about Nova and Supernovae. Finally we...
In this lecture we discuss how a low mass star evolves off the main sequence when it runs out of hydrogen to fuse in its core. We follow its...
In this lecture we discuss the formation of planets and the discoveries of exoplanets around other stars.
In this lecture we continue to discuss the process of star formation from the fragmentation of a giant molecular cloud, to the collapse of t...
In this lecture we discuss the hydrogen spin flip transition that produces radiation at 21cm. We also describe the rich and complex molecula...
In this class we discuss binary stars and how they are used to determine stellar mass. We then begin to discuss the Interstellar Medium.
No podcast today. Camera kept cutting out again.....
In this lecture we discuss the basic properties of stars and the stellar Classification system (OBAFGKM) as well as luminosity classes (I th...
The camera cut out again but we got 40 minutes of discussion on the properties of the Sun and the process of nuclear fusion.
In this lecture (back from illness, reading week, and the midterm exam!) we talk about "seeing", different telescopes, why we go to high alt...

In this lectrure we discuss the varous "type" of light across the Electromagnetic spectrum (radio, IR, visible, etc.) and then also how soli...
In this lecture we explore the many uses of Newton's version of Kepler's law as a tool to determine the masses of objects in the Universe. W...
In this lecture we explore Newton's laws of motion and gravity and show how how he unifies terrestrial and celestial motion. We provide and...
In this lecture we finish our discussion of Galileo's contribution to the Heliocentric model and begin to discuss motion in the Universe via...
In this lecture we begin to discuss the rise of the heliocentric model of the Universe/Solar System in the rennaissance. We describe the Cop...
In this lecture we discuss the geocentric model of Ptolemy, the heliocentric model of Aristarchus and how Hipparchus tested it using the con...
In this lecture we continue to examine some ancient (and still true) observations about the Universe such as dailly, direct, and retrograde...
