“Audio Podcasts” and similar random podcasts

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.
