In my third class of my Introduction to Planetary Science and Astronomy class at CSUDH, I talk about the many types of telescopes and explore the Moon. The video is below. For more information about the class, see my class page, http://planetary.org/bettsclass
This lecture covers optical, radio, and space telescopes, the history, exploration, and importance of the Moon to our Solar System understanding, as well as impact cratering, and lunar tides and phases.
In the next class, I will talk about Venus and also compare the atmospheres of Venus, Earth, and Mars.
