Intro Astronomy 2014. Class 2: How We Explore Space

Go Back

Lecture 2 of Dr. Bruce Betts' online Introductory Planetary Science and Astronomy course covers easy things to see in the night sky without a telescope, and the electromagnetic spectrum (from gamma rays to visible to radio waves) -- what it is, and how and why we use different wavelength regions to explore planets and even learn their compositions. The class concludes with guest Mat Kaplan, Media Producer for The Planetary Society and Bruce and Mat record a What's Up segment for Planetary Radio. Recorded at California State University Dominguez Hills.

Stellarium that he mentioned in this video is freaking awesome. with minutes of downloading it, I figured out how to use it, found Jupiter, Mars and a whole bunch of other objects in my backyard sky. Freaking awesome program. http://www.stellarium.org/en_CA/

I have gone thru Lecture 2 three times and could not find the random space fact. Am I missing it or is it not called out ?
