In a somewhat peculiar image, the POT caught the Sun “smiling”, which caused a sensation among astronomy fans, since such an optical illusion can rarely be observed, but the “eyes” and “mouth” that are seen on the surface of the star of the solar system have a Explanation.
The curious image was taken by the NASA Solar Dynamics Observatory on October 26 and the black spots, which form the “eyes” and the “mouth”, have been captured in ultraviolet and are known like coronal holes.
How are the coronal holes of the Sun captured by NASA formed?
The coronal holes are basically regions of the surface of the Sun where it exists an unusually low coronal mass density, that extends over the surface where the solar magnetic field opens out into space. They are located in the solar corona, the outermost layer of the Sunwhich is composed of plasma and extends more than a million kilometers from its origin on the chromosphere.
The dark regions representing the coronal holes They are born as a result of the X-ray observation of these areas. In them, the magnetic field is unipolar, opening to space. High-speed solar winds emerge from these areas, heading back into interplanetary space.
This solar phenomenon can cause non-hazardous disturbances on Earth. “When a coronal hole is placed near the center of the solar disk facing the 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”, indicates the portal Space Weather Live.
