Solar Cycle

At various times, something that relates the study of physics to our daily lives goes unnoticed. At other times we don’t stop to think about what’s around us. The Universe is full of wonders like stars, planets, etc., which we don’t always stop to observe. We know the phases of the Moon, but not everyone knows that the Sun also has phases.

We know that the Sun is a star, the biggest star in the solar system. All other planets, asteroids and other stars revolve around it. The Sun is basically composed of hydrogen and helium. Inside it, nuclear reactions occur that create spots on its surface, better known as sunspots.

As the temperature in the Sun’s corona rises, the solar winds are produced. The solar wind is a continuous flow of charged particles that also causes the Sun to lose mass.

In addition to particles coming from the solar winds, there are also large mass ejections that are associated with elevations on the surface of the Sun. These ejections are a result of solar cycles.

Solar cycles are activities on the surface of the Sun that last about 11 years. When the solar atmosphere becomes more effervescent, it releases flames that can reach sizes equal to those of small planets. These moments are called solar maximum because the prominences reach higher peaks.

Although it has cycles that reach 11 years, the Sun also has oscillations that can last hundreds of years. After the period of high peaks, the surface of the Sun becomes “quiet” again, that is, it undergoes a period of stability.

According to the University of Southampton, by the year 1985 the Sun reached a strong peak. After that year solar activities decreased.
