Anonews: We don't know many completely surprising details about our own Sun. On the grand scale of the entire known universe, it seems that our Sun is a fairly average star. Despite this, it produces so many different strange phenomena that scientists and independent researchers are just beginning to understand something.
It looks like a nuclear reactor capable of producing complex plasma currents deep into outer space, “solar tornadoes,” solar flares, and perhaps even spiritual effects on people and creatures that inhabit planet Earth.
Now, the new data reported by New Scientist seems to add an interesting new enigma to the long list of mysteries of our Sun, the great center of our solar system and life itself.
According to a report recently published in the Astrophysical Journal, our own Sun “grows” and “contracts” over an 11-year cycle, about 0.6-1.2 miles wide, or 1 to 2 kilometers wide. It is as if our Sun “breathes” and fluctuates in its size, probably because it is a flaming ball of gas.
Given the relatively huge size of the Sun, you can call it an extremely small, almost imperceptible "inhalation and exhalation" like the lungs. The Sun's additional Width at certain times in this eleven-year cycle is only about 0.00029 percent of the Sun's radius.
A team from the University of the Côte d'Azur and the New Jersey Institute of Technology has been able to notice this subtle difference by carefully studying the plasma streams that leave the surface of the Sun and then return to it.

These are the notorious high-energy ionized gas filaments that sometimes break off and essentially become solar flares. Ironically, the sound frequencies emitted by these plasma waves that roll across our Sun are not too different from the actual musical frequencies perceived by human ears.
A detailed description of this musical concept has been provided in this article:
“Let's say you have a saxophone because you like jazz. You play the notes, the sound comes out, and you're good. Now, if the tube inside the saxophone suddenly expands outward, the pitch of the note will drop. Squeeze it all together and the height will be higher.”
Depending on the current size of the Sun in this eleven-year cycle, the frequencies of the waves emanating from it change. It is reported that scientists on Earth can already measure these differences very accurately. However, it took 21 years of observations with a pair of different NASA space telescopes.
So what is the eleven-year cycle? As you might have guessed, this is the solar cycle.
The Sun's global magnetic field goes through regular 11-year cycles, at the peak of which its poles change places. These fluctuations also determine the cyclical activity of the star, including the intensity of radiation and ejection of matter. It is believed that these processes are directed by the work of the "magnetic dynamo" in the interior of the Sun, where huge masses of incandescent charged plasma are mixed under the influence of magnetism and convection, although this mechanism is very poorly understood.
