Scientists claim that this wind is totally different from the air current on Earth.

The Parker solar probe NASA has first detected the strange sounds produced by the wind that emanates from the Sun, according to an article published by the Applied Physics Laboratory (APL) of Johns Hopkins University in the USA, which operates that space vehicle.
Composed of electrons, protons and ions, that wind crosses the solar system at approximately 1.6 million kilometers per hour, sweeping everything in its path. The Parker Solar Probe listens to the “little birdiesand whispers that hint at the origin of this mysterious wind. “That wind is” completely different “from the terrestrial air current, said APL scientist Nour Raouafi.
Researchers have studied solar wind for more than 60 years, but they are still baffled for some of their behaviors. While it is known that it originates from the Sun’s crown, the solar wind, for example, does not slow down as it moves away from the king star. On the contrary, “it accelerates and has a kind of internal heater that prevents its cooling while sliding through space, “says the article.
“Amazing sound waves”

With the growing concern about the solar wind capacity of interfere with satellites and disturb the electric power networks on Earth, it has become essential to understand it better. “We expected to make great discoveries because we are entering unknown territory“But what” we are seeing goes beyond what we imagined, “Raouafi said.
This probe is equipped with an instrument known as ‘FIELDS’, with which it is able to intercept the electrical and magnetic fluctuations caused by plasma waves. The Parker solar probe can ‘hear’ when waves and particles interact with each other, recording frequency and amplitude information about those plasma waves that scientists can translate into “amazing sound waves.”
