The Universe Sings

Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space. Actually, the number as far as we can tell is about 13.8 billion light years. Or at least, that's the bit we can see. Trouble is, most of it's Dark. Today we hitchhike through the galaxy with Associate Professor Paul Francis from the Mount Stromolo Observatory.  Listen to the wondrous sounds he generated from spectrographs. In this episode of Fuzzy Logic, the universe sings for us. Brought to you by Eleanor and Rod
