The record of baryon acoustic oscillations (white circles) in galaxy maps helps astronomers retrace the history of the expanding universe. These schematic images show the universe at three different times. ... These variations included the signal of the original baryon acoustic oscillations (white circle, right). As the universe has expanded (middle and left), evidence of the baryon oscillations has remained, visible in a "peak separation" between galaxies (the larger white circles). ...

Sound waves cannot travel through the vacuum of space. ... These electromagnetic waves can be recorded by devices called spectrographs on many of the world's most powerful telescopes. On this web page, I have converted these electromagnetic waves into sound waves. I've also reduced the frequency 1.75 trillion times: the original frequencies are much too high for humans or even dogs to hear. This allows us to listen to many parts of the universe for the first time. ...
