Astronomy Cast puts those Ipods and MP3 players to good use in an educational environment. Astronomy Cast, as you’ve probably guessed, is a series of podcasts about Space Science. This week’s episode, “Space Junk,” is about pollution in space caused by humans. In addition to the podcasts Astronomy Cast hosts a discussion forum for amateur astronomers. Astronomy Cast is sponsored by the National Science Foundation.

Applications for Education
Astronomy Cast has a great education section where school can submit questions for Astronomy Cast to include in upcoming podcasts. The “ask an Astronomer” section of the Astronomy Cast links visitors to the California Institute of Technology’s astronomy web page called Cool Cosmos. Cool Cosmos has a large selection of videos and classroom activities suitable for students in elementary school through high school.
