While surfing through hyperspace to find more detailed information about Calvera, presumably the Earth’s closest neutron star located in the constellation Ursa Minor which has been discovered by astronomers just a couple of days ago, I found a very fascinating article dealing with audible tones emitted by the Sun.
Apparently circulation within the Sun’s convection zone causes emerging bubbles to squeeze the plasma as soon as they reach the solar surface. As a result, some areas on the surface are visibly brighter than others caused by upward and downward movement of plasma. These very low-frequency vibrations have recently been recorded and made audible by SOHO, the Solar and Heliospheric Observatory spacecraft of ESA and NASA designed to observe the Sun.
