Cool Cosmos

I've never quite understood all the various spectrums of light, including infrared. This latter is especially ironic since I, along with a lot of other folks, use infrared light nearly everyday of our lives. Most frequently, we are pointing handheld little plastic rectangles called "remote controls" at TVs, CD players, DVD players, and all sorts of gadgets and controlling them using infrared light.

It's been also amazing to see the incredible beauty of infrared out in space which the Hubble Telescope has shown us. The Cool Cosmos site has a tutorial about infrared astronomy which is both "educational" but beautiful, too. Take a look! Cool Cosmos is a great site and has much else to offer!
