STARS SINGING TOGETHER

The stars might be singing – but, since sound can’t propagate through the vacuum of space, no one can hear them.

Is there an actual harmony of the spheres? A chance discovery by a team of researchers has provided experimental evidence that stars might generate sound. They announced their discovery March 23, 2015.

Astronomers have used the words star and sound in the same sentence before. Asteroseismology is a study in which tiny oscillations within a star can be used to probe its internal structure. In those sorts of studies, astronomers effectively turn tiny variations in a star’s light into sounds. See a video about asteroseismology below.

Now a group of physicists is talking about something else: actual sound generated by the stars themselves. The scientists – including Dr John Pasley of the Department of Physics at University of York – said in a statement:

The study of fluids in motion – now known as hydrodynamics – goes back to the Egyptians, so it is not often that new discoveries are made. However when examining the interaction of an ultra-intense laser with a plasma target, the team observed something unexpected.

The Bible confirm that the stars singing together thousand of years before the discovery.

"As the morning stars sang together and all the angels shouted for joy? (Job 38:7) 

Scientists … realized that in the trillionth of a second after the laser strikes, plasma flowed rapidly from areas of high density to more stagnant regions of low density, in such a way that it created something like a traffic jam. Plasma piled up at the interface between the high and low density regions, generating a series of pressure pulses: a sound wave.

However, the sound generated was at such a high frequency that it would have left even bats and dolphins struggling! With a frequency of nearly a trillion hertz, the sound generated was not only unexpected, but was also at close to the highest frequency possible in such a material – six million times higher than that which can be heard by any mammal!

Scientists can record the sound of Stars The technique, called "stellar seismology", is becoming increasingly popular among astronomers because the sounds give an indication of what is going on in the stars' interior.
