Giant Pipe Organ In The Solar Atmosphere
Science Daily — Astronomers have found that the atmosphere of the Sun plays a kind of heavenly music. The magnetic field in the outer regions (the corona) of our nearest star forms loops that carry waves and behave rather like a musical instrument.
The acoustic waves can be extremely powerful and reach amplitudes of tens of kilometres per second. Professor von Fay-Siebenburgen adds, “we found that the waves are often generated at the base of the magnetic pipes by enormous explosions known as micro-flares. These release energy equivalent to millions of hydrogen bombs. After each micro-flare, sound booms are rapidly excited inside the magnetic pipes before decaying in less than an hour and dissipating in the very hot solar corona.”
