The Space Research Institute published a sound with the sound waves that it managed to get after dealing with the different frequencies that produce the vibrations of the main star of our solar system. How did the sun ring?
NASA recently clarified the issue by publishing the sounds of the main star of our solar system.
To realize this audio, which may surprise, the NASA Solar Observatory The company of the European Space Agency has captured for more than 20 years the different vibrations of the movements of the sun.
"All his waves, his curls and his eruptions were captured," said the space research institute. web page
In order to convert these vibrations, which are not perceptible to human ears, NASA scientists used Doppler velocity data, averaged on the solar disk and, by means of a procedure, removed the effects of the movements of the spaceship that captured them.
The data was then filtered at about 3 MHz to select the own sound waves (and not supergranulation and instrumental noise) and finally, interpolated the missing data and scaled the data (they l & # 39; have accelerated by a factor of 42,000 to put it in the audible range of human hearing (kHz)).
"We do not have a simple way of looking inside the Sun.We do not have a microscope to approach the Sun.Then use a star or the vibrations of the Sun. lets us see the inside, "says Alex Young, deputy director of science at the Sun.
