Decode the mysterious phenomenon at the south pole of the Sun.

The NASA Center explains the mysterious phenomenon that takes place on the southern end of the Sun, in fact, the appearance of a giant coronary crater on the surface of the Sun, where wind speeds are up to 800km per second.

Daily Mail reported that the mysterious phenomenon on the Sun is in fact the appearance of a giant Japanese coronary crater in the area near the South Pole. The researchers said that in the area of ​​the giant pit, the velocity of the winds can reach 800km per second.

The mysterious phenomenon that occurred on the Sun was recorded on January 1, 2015, by the Atmospheric Imaging Assembly (AIA) device on the Solar Solar Observ Observatory observatory spacecraft. In NASA's photo, the coronary crater is a darker area than the surface of the Sun.

The corona ring is the solar aura where the magnetic field escapes and enters space. Atomic particles follow the magnetic field to escape from the Sun instead of being trapped in the atmosphere near the surface, trapped atomic particles will be burned and shine. The light in the aura region has the weaker atomic lines flowing out of the Sun, making the area of ​​the coronary rim look darker than other areas on the Sun's surface.

The first images of the coronary crater were recorded by astronauts on NASA's Skylab space station in 1973 and 1974. This type of pit may appear for a long time of about 5 years or longer, but their shape is always changing. The researchers identified that the coronary craters have an important role in understanding cosmic weather, because high-speed atomic currents originating from pits have velocity three times faster than natural currents. death elsewhere.

Atomic currents escaping from the Sun are also known as solar winds, which usually have a velocity of about 400 km per second, but every time the coronary crater appears, the solar winds can reach speed 800km per second. When high-speed atomic currents enter the Earth's magnetosphere, they cause ion particles in the radiation to be accelerated and cause many familiar phenomena such as magnetic storms or aurorae.

Until now, researchers have not found the cause of this mysterious phenomenon, they only know that these pits are related to areas where magnetic currents escape and enter. Space instead of curling up on the Sun's surface as usual.
