Witness our universe in a whole new way! This video series (in 720p High Definition for Apple TV and hi-res monitors) highlights some of the most exciting discoveries from NASA’s Spitzer Space Telescope. In-depth ‘Showcase’ features, striking ‘Gallery Explorer’ montages, and other whimsical specials take you beyond the visible to a universe of dust and stars hidden from Earth-bound eyes. Spitzer is the infrared component of the NASA Great Observatory program which also includes Hubble (visible), Chandra (x-ray), and Compton (gamma ray). For faster, iPod-compatible downloads search for the companion ‘Hidden Universe’ standard definition feed, also available on iTunes. One year ago, astronomers announced the discovery that seven roughly Earth-sized worlds orbited around the nearby star TRAPPIST-1. Now a year later, additional data have refined our understanding of these planets.We now know more about the TRAPPIST-1 system than any other solar system other than our own.

NASA’s Spitzer Space Telescope is a space-based infrared observatory, part of NASA’s Great Observatories program (which also includes Hubble, Chandra, and Compton). These podcasts offer information about the science discoveries, astronomy, and more. During the infancy of our solar system, when our planets had not yet settled down into their orbits, this was a dangerous place to live. The planets wobbled and jostled around left over asteroids, comets and other debris floating in between their orbits, causing frequent collisions throughout our solar system.
