Cool Space

The California Institute of Technology provides a site that has some great tutorial material on infrared and multi-wavelength astronomy. Also, the many images and videos will make multiple visits worth your time even after you have learned all the basics!
The material also covers applications to biology, geology, oceanography and more.
Interestingly, the site warns readers when material is written for those older then 14 and refers the reader to their parents or guardians if the text is too difficult. I wonder just who the average adult is supposed to get help from.
