s2e5: Exotelescope Expeditions

Exo-planets, sure. Exo-moons and -comets? Fine. But exo ... telescopes?! Emily is going out on a limb in this episode, expanding the definition of telescope to include things that measure stuff in space, and we're here for it! Which means we really do have a few telescopes out there beyond the Solar System, in the shape of Voyagers 1 and 2, with a few more waiting in the wings.On the web: syzygy.fmHelp us make Syzygy even better!
