The Stars Sing For Moosh who just got her hearing back. But I thought you others might like this too. All visible stars in the sky including our sun are not solid. They are molten or liquid in the core slowly becoming gaseous towards the outer layer. Shockwaves travel through this medium at much higher speeds than sound on earth. As a result stars ring like bells with the waves reverbrating through them for very long times. The waves are caused by mass disturbances like solar flares and the uneven way energy travels out from the core. Many of the vibrations are in the acoustic or audible range. The vibrations get encoded in the stars light similar to the way optical audio works in modern stereo systems. Modern digital audio tech makes it possible to retrieve this encoded sound from starlight. It might be cool to sample some of this and try to compose something. Star Song youtube/watch?v=G-6u1sMN4yU Pulsars a different deal, collapsed remnants of massive stars that at the end of there life went supernovae, blowing away most of their mass. Not visible with the eye. The remnant is dense neutron star about the size of earth spinning many times a second. The angular momentum of the stars spin is concentrated like when figure skaters pull their arms in. Some emit a searchlight like beam of intense X-rays and particles. There is also intense magnetic fluctuations around these stars. All this happens in some acoustic frequencies too. The beats are actually the spin rate of the stars, massive objects, the mass of Jupiter or more. These sounds were retrieved from the X-ray light of these objects. astro.cornell.edu/~deneva/psr_sounds/pulsars_sounds.htm This last pulsar is the coolest! It almost sound like house music. youtube/watch?v=uHEVo-LkDrQ Look up in the sky tonight if you can see the stars. They are singing to each other and to us! Who knows? Theres enough going on inside a star that it could have some kind of awareness!
