After 140 years of monitoring .. Solve the "biggest secrets of the sun"

Two recent studies, conducted by the National Atmospheric Research Center (NCAR) in the United States, shed light on the main mysteries surrounding the sun that have fascinated scientists for decades.

After nearly 140 years of monitoring, scientists have been able to determine how to predict the next sunspot cycle, which could present a great scientific advantage to the Earth's surface, according to reports from the University of the Corporation for Research on the Atmosphere.

Scientists already knew that the solar cycle lasted about 11 years (phenomena such as solar wind, solar flares and solar explosions), but it was difficult to predict exactly when this cycle would end and when would begin a new cycle.

However, new studies have allowed scientists to identify events that clearly reflect the end of the solar cycle.

Using computer simulations, the experts studied how to start a new cycle of sunspots and found that the so-called "solar tsunami" (the hot plasma wave that crosses the sun's surface ) could explain the shift from one solar cycle to another.

The scientific team badumes that the process of initiating a "solar tsunami" is characterized by the movement of coronal dots in bright colors (a short flash of ultraviolet radiation), whose movement and disappearance eventual are what is said of the end of the solar cycle.

"By combining these various observations over several years, we have been able to reconstruct these events and give a totally new insight into the displacement of the inner part," said astronomer Scott Mackintosh, a scientist at the National Research Center. on the atmosphere of the United States. Sun in the solar cycle ".

The more accurate prediction of sunspot cycles badociated with solar storms will help better predict these phenomena that may affect the Earth's electronic infrastructure.

Scientists believe that the current solar cycle is about to end and that it should end by the first half of 2020.
