Crash Course Astronomy - a series of short instructional videos by Phil Plait
In January Phil Plait began delivering a series of ten to twelve minute long introductory lectures about astronomy that were recorded by PBS Digital Studios and released as YouTube videos. They just released a humorous video of outtakes. Watch at the one-minute mark, as Phil tries different hand gestures for showing the orientation of the Earth’s axis.
Topics so far in this series are:
#1 Introduction to Astronomy
#2 Naked Eye Observations
#3 Cycles in the Sky
#4 Moon Phases
#7 The Gravity of the Situation
#9 Introduction to the Solar System
#10 The Sun
Back in 2011 Phil also gave a TED talk on How to defend Earth from Asteroids.
