This video series (standard definition/iPod compatible) showcases some of the most exciting discoveries in infrared astronomy from NASA's Spitzer Space Telescope. Looking beyond the visible spectrum of light, Spitzer can see a whole new universe of dust and stars hidden from our Earth-bound eyes. Spitzer is the infrared component of NASA's Great Observatories program, which also includes Hubble (visible), Chandra (x-ray), and Compton (gamma ray). This series is also available in high definition. For high-resolution viewing on your Apple TV or high-res monitor search for the companion 'Hidden Universe HD' feed, also available on iTunes.

Hidden Universe is Interesting and Educational

I enjoyed these podcasts very much. The visuals are beautiful, the explanations clear and the science fascinating. They are so clear and interesting that even my 10 year old was engaged and learned something about star formation. Can't wait to see more!
