The sun is about to ... disappear?

Scientists predict the sun is about to enter a less active phase. By 2020, black streaks will disappear in a relatively long time.

However, scientists say that this is not worrying. The action of solar waves has little impact on the amount of light and warmth it radiates. The calmer sun is almost entirely effective. The satellites and the grid system are only slightly affected, and perhaps global warming will slow down.

Scientists don't know why the sun is about to become "gentle". But the current signs are proving that.

Frank Hill of the National Solar Observatory (USA) and his colleagues made this prediction based on three changes: the black streaks on the sun are fading, the aura radiating from the poles of the sun is also weak. go, and the disappearance of the sun rays.

' These three signs show that it is possible that the sun is about to enter a less active state and it takes a long time to recover,' said Richard Altrock, astrophysicist at the National Air Force Research Laboratory. know.

This cycle will start in 2020. Experts say the sun has started to become more smooth for about 4 years now, because there are only a few black spots - areas with stronger magnetic fields.

The sun has a strong magnetic field when there are many black streaks, solar winds and fast-moving particles, sometimes hitting the earth. In the 22-year cycle, the sun's magnetic field changes in the North-South direction, creating a black streak cycle lasting 11 years. At its peak, as in 2001, black streaks appear daily, while solar rays and storms appear frequently, adversely affecting satellites.

According to David Hathaway, the leading solar research scientist of the US Aerospace Agency (NASA), the current cycle, starting in 2009, will be the weakest cycle in this century.

Matt Penn at the National Solar Observatory, said that since 1998, the strength of magnetic fields from black streaks has decreased. If it continues at the current rate, the solar field will become very weak, making it difficult to form black streaks around 2020.

Light columns above and below the surface of the sun are early signs of a solar storm, but these light columns have not yet been formed for the cycle starting from 2020, meaning that the cycle from 2020 will mark little Sun's activity.

Scientists recommend that people should not be afraid because the less active sun phase will only reduce the magnetic field and ionizing gas, not reduce the light and warm air.

Some argue that it is heat radiation from the sun that warms the earth, but very few scientists agree with this. The earth is still warming when the sun's activity decreases.

According to Andrew Weaver, a climate scientist at Victoria University , the sun's activity can have a small impact on global temperatures, but nothing compared to the effects of human activities on emissions. CO2 and methane increased. In 2010, the sun was very weak, but it was the hottest year in more than a century.
