The sound of silence: Listening to the Universe

We are most fami liar with what the Universe looks like in “normal” light. However, the worl d around us—our Sun, the planets, the stars beyond, galaxies and even the l eftovers from the Big Bang that started it all—is abuzz with sounds – sound s that we cannot hear directly, although we can transfer the signals we rec eive from this wide variety of astronomical sources to the range accessible to human hearing. Sometimes, signals are mistaken for the telltale signs o f alien civilisations. We will explore the unheard side of the Universe – l isten rather than look!
