In a somewhat unusual image, NASA recorded Salt “smiling”, which caused a sensation among astronomy enthusiasts, since this kind of optical illusion is rarely seen, but the “eyes” and “mouth” seen on the surface of a solar system star have an explanation.
He took an interesting picture NASA Solar Dynamics Observatory October 26, and the black dots, which form “eyes” and “mouths”, were captured by ultraviolet and are known like coronary holes.
How are the coronal holes of the Sun that were recorded by NASA formed?
Bad coronary holes are basically surface areas Salt where it exists unusually low coronal mass density, which extends across the surface where the sun’s magnetic field opens into space. They are located in the Sun’s corona, the outermost layer Saltwhich consists of plasma and extends more than a million kilometers from its origin in the chromosphere.
The dark areas that represent coronary holes They are born as a result of X-ray observation of these areas. In them, the magnetic field is unipolar, it opens towards space. High-velocity solar winds exit these regions, returning back into interplanetary space.
This solar phenomenon can cause harmless disturbances on Earth. “When a coronal hole is placed near the center of the solar disk facing Earth, these hot gases flow towards the planet at a higher speed than the normal solar wind and cause geomagnetic disturbances and increased auroral activity,” writes the Space portal.
