German scientists have identified the reason why our Sun goes on rebellion and gradually becomes gentle every 11 years.
Scientists all over the world have identified the "solar cycle" that takes place every 11 years , including the maximum activity with the increase in solar flames, storms that release extreme amounts of matter. optical . more or less affected the Earth at the beginning of each cycle, then weakened again. But what causes the Sun's rebellious cycle is still a mystery.
New research published in the journal Solar Physics of the Independent Research Institute Helmholtz-Zentrum Dresden-Rossendorf (HZDR - Germany) has found the answer.
The sun does not rebel itself, the new work said. In the past, it was believed that most of the solar system planets were dominated by a star mother. But no, the Sun's "humid bouts" involve three large and close planets: Venus, Jupiter and our Earth .
The strong energy of tides from Venus, Earth and Jupiter, planets of large and close enough (located at 2,3 and 5 from the Sun) have created enough gravitational force. Large to cause changes to the plasma on the surface of the Sun.
Every 11.07 years, these planets will unintentionally lie in a position that causes gravity to synthesize them from the strongest impact on the parent star, causing the Sun to "rebel". During this period of maximum activity, the Sun will appear more dark spots when observed with modern telescopes.
To reach this conclusion, the researcher Frank Stefani, the lead author of the study, said he and his colleagues have looked at data on the activity of the Sun and the planets around it for nearly 1,000 years. The coincidence of the solar cycle and the activity of the three planets is evident during 90 continuous cycles.
Although the combined gravity of all three planets is not strong enough to directly change the "interior" part of the Sun, it is sufficient to alter the behavior of a liquid or a kind of unstable plasma-like material. , collectively referred to as "Tayler instability".
Because of being influenced by external factors, "Tayler instability" itself is different in each cycle. For example, in the 17th century, a weak solar activity cycle caused a "mini ice age" in Europe.
The good news is the forthcoming cycle of the Sun - the 25th cycle, which lasts from 2023 to 2026 - is said to be "average level". The biggest threat that can occur in the Sun's strong operating cycles is that energy storms threaten to destroy Earth's electrical and satellite systems.
