TL;DR Summary

While there is no sound that humans can hear in the vacuum of space, there are still waves that propagate through the low-density plasma in interplanetary space. The solar wind, released by the Sun, creates plasma waves that can be converted into radio waves and then back into sound when they reach Earth's ionosphere. These waves have implications for star formation and can be used in asteroseismology to study the interior properties of stars. Additionally, supermassive black holes can generate plasma ripples that produce musical notes, although they are too deep for humans to hear. In the Solar System, there are possibilities of finding extraterrestrial sounds on planets with atmospheres, such as Venus and Mars.
