The Sun's magnetic field will polarize in May

The Yomiuri daily issued on April 21 led the source of Japan's National Astronomical Observatory (NAOJ), saying that the electrodes on the two halves of the Sun's hemisphere will reverse and divide into four poles in May. .

The anodes will appear at the North and South poles while negative electrodes will appear at the two poles of the Sun.

According to NAOJ, the same phenomenon that happened 300 years ago made Earth's temperature drop slightly.

The research team, led by NAOJ professor Saku Tsuneta, analyzed data related to the Sun's electrode and confirmed that the magnetic pole at the North Pole has begun a reversal process since July 2011.

Researchers also found that the magnetic field at the south pole - thought to be reversed in parallel with the north pole - is tending to form a 4-pole magnetic field. Scientists have yet to explain the cause behind this change. However, most claim that this strange polarization is related to the increase and decrease of the number of sunspots of the Sun over a period of 11 years.

The current solar-black streak cycle has lasted for nearly 13 years. The same situation occurred around the 17th-18th century, when the average temperature of the Earth's northern hemisphere fell 0.6 degrees C. Professor Tsuneta's team believed this quadrupole model also happened at that time.
