Hidden Universe: NASA's Spitzer Space Telescope

Hidden Universe: NASA's Spitzer Space Telescope
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.
