There is a huge dark spot on the opposite side of the Sun

At the end of 2019, our SunSun was entering his 25e activity cycle. And quickly, the astronomersastronomers had announced that it could turn out to be particularly intense. They seem not to have been mistaken. For more than two years, the average level of activity of our StarStar proves to be two to three times higher than what the researchers expected!

Today, thanks to the techniques ofhelioseismologyhelioseismology, researchers have just updated a huge sunspot on the far side of our Star (the side opposite the Earth). A group of sunspotssunspots, in reality. It created a helioseismic echo — the data the researchers detected — larger than any detected in the past five years. What to suspect that an ejection of massmass coronal could occur from this far side in the coming days.

Should we fear this gigantic sunspot?

Meanwhile, researchers continue to try to better understand what is going on inside the Sun. The mechanisms that govern sunspot activity. A team from the NasaNasa has just published new results interesting in the mattermatter. By processing 22 years of data, astronomers have discovered that the current cycle of sunspot formation — it begins when a sunspot appears about 30 degrees from latitudelatitude and migrate toequatorequator — could be weaker than the previous one and that the long-term trend of the decline of the Sun’s magnetic fields should continue.
