KLIKMATARAM – Parker Solar Probe NASA launched in 2018 to explore the mysteries of the sun by traveling closer than spaceship anywhere before.
Three years after launch, Parker Solar Probe NASA finally managed to touch Crown Sun.
Parker Solar Probe NASA, on April 28, 2021, experiences certain magnetic and particle conditions about 8.1 million miles above the sun’s surface.
It informed scientists that it had crossed the critical surface and for the first time and finally entered atmosphere Sun.

Unlike Earth, the sun does not have a solid surface. But he has atmosphere very hot, made of solar material that is bound to the sun by gravity and magnetism.
As the increased heat and pressure pushes the material away from the sun, it reaches a point where gravity and magnetic fields are too weak to hold it in.
That point, known as the Alfvén critical surface, marks the end of atmosphere sun and the beginning of the solar wind.
The solar matter with the energy to make it cross that boundary becomes the solar wind, which drags the sun’s magnetic field with it as it travels across the solar system, to Earth and beyond.
