The American space agency NASA has observed a very large dark region in the Sun, for which the term coronal hole is used.

Contrary to the name, it is not actually a crater or hole on the surface of the Sun, but rather a region where the temperature is lower than the rest of the star.

Because of this, this part is not as bright as other regions of the Sun and appears dark.

Alex Young from NASA said that this coronal hole is spread over an area of ​​3 to 4 lakh kilometers and is 20 to 30 times bigger than Earth.

According to experts, such coronal holes are not uncommon but quite common.

Such regions are part of the Sun’s normal activity, but according to experts, not enough is known about them.

Alex Young said that the coronal hole emits high-speed solar winds with speeds of 500 to 800 kilometers per second.

The winds from this new coronal hole in the Sun will reach Earth by the end of this week.

Alex Hung said that we will probably see the impact by March 24.

Such solar winds are likely to affect the power system, but according to experts, the effect of this new wave will be seen in the form of aurora borealis.

According to Alex Young, such solar waves will become more common in the coming years, and the magnetic fields of these waves can affect power systems and satellites.
