The Bad Astronomer, Phil Plait, is one of my favorite science bloggers. He mixes skepticism, science and humor into his work. He has produced 3 high quality short videos for Hulu.com. California 8th grade science standards include the universe and the solar system and these 3 videos are a good supplement. There are short commercials before the main content of the videos.

The first is about the changing landscape of Mars using videos and images from current Mars probes.

The second one covers super-massive black holes.

The third video covers galaxy interactions.
