Intense solar eruptions.

Over the weekend that just passed, US astronomersobserved medium intensity solar eruptions on the sun, according to Descopera and the Dailymail. However, the phenomena investigated by the specialists from NASA's Solar Dynamics Observatory are the most spectacular events of this type discovered this year. The events were classified as the most intense solar eruptions.

Although researchers had been warning since two years ago that the sun's activity has been at it's weakest over the last century, the most intense solar flares from April until recently were detected on the surface of the sun.

The most intense started on Friday, July 22. The first one occurred in the area known as Active Region 12567. The second one - the most intense one - appeared in the area known as Active Region 2565. The third one was located in the area known as Active region 2567.

Solar eruptions pose no threat to our planet.

Solar eruptions are powerful and short bursts of radiation from the sun's surface. Although they are not dangerous for our planet, they can still enter the Earth's atmosphere and cause failures of GPS systems and the telecommunications systems.

A new ice age?

The phenomena observed last weekend are different from those one seen earlier this year because this time, astronomers didn't observe solar dark regions on the surface of the sun.

However, experts say that if such phenomena were to be repeated constantly, theEarth could pass through a 'mini ice age'.

During the period of maximum activity of the sun, dark areas of extremely large dimensions but also very powerful solar eruptions can be observed on its surface. On the other hand, when solar activity is the weakest, the phenomenon is going to reverse.

In a study from last year, it was noted that solar cycles can be predicted and that these types of successions will neutralize each other between 2020-2030. For this reason, scientists say that Earth could be witnessing a 'mini ice age' similar to the one produced between 1646-1715.
