Here is the music of Sun
recorded voice Star
A group of British researchers for the first time makes it audible to human ears the harmonies produced by the magnetic arches. The tune is a real bore, but will better understand our astro MARCO EASTER source Repubblica.it
THE SUN has always been a source of inspiration for musicians and singers. But now, scientists were able to record and to make audible to humans, the music that the star itself is capable of producing. Musical harmony, which is generated by the magnetic field in the outer part of its atmosphere, very similar to that of the strings of a guitar. And that, surely, unaware of its existence the same Lucio Battisti, when, in 1971, charmed the Italians with his "Song of the Sun."
The recording was made by the research team that, three years ago, during a meeting of the Royal Astronomical Society, was able to explain in detail the phenomenon of this particular solar harmony. Robertus von Fay-Siebenbürgen, who heads the team of astronomers from the University of Sheffield, pointed out the enormous electrical arcs that are generated in the solar corona, can produce sound waves that propagate like those of a guitar string. In still other cases, produce waves generated by a similar wind instruments. For
get to play the sounds, the British scientists have used satellite images captured by these magnetic strings - which can reach a length of 96 thousand kilometers - then coming to speed up the frequency, so that even the human ear can hear. As noted already in 2007, in fact, the frequency of sounds is below the minimum audible by humans.
There is nothing compelling in this melody for admission of the person who has heard, is a "real trouble". "To hear these sounds for the first time, issued by a source so big and powerful, it was nice - the professor said talking to the Daily Telegraph - We are faced with music that will allow us to study the Sun from a new perspective and to better understand what happens in the outer layers where temperatures reach millions of degrees. "Magnetic arcs, experts note, vibrate "pinched" by powerful explosions that occur at their base. Acoustic waves generated by each of these explosions travel at a speed that can vary from 45 thousand to 90 thousand miles per hour and can release energy equivalent to millions of hydrogen bombs.
The research of British scientists could help astronomers to predict solar storms terrible. Last week, the NASA recalled how solar activity is gradually increasing: this will result in the release in the solar system by 2013, magnetic energy levels high. For experts, this could send in a short time on tilt all electrical equipment, leaving the planet to the "dark." They may also skip all the communication systems and GPS devices.
"To study the music of the sun - highlighted in this regard, Professor Fay-Siebenbürgen - might enable us to better understand and predict these solar storms." For the teacher to know the future behavior of the Sun are encouraging: "These strings oscillate like a guitar string or a musical instrument in the air to breath. Over time, the waves gradually die, and this will help us better understand what happens in the solar atmosphere."
