Scientists studying the solar minimum of the Sun have found an inexplicable phenomenon occurring on the surface of the Sun, which makes some areas of the blazing giant significantly hotter than others.
Researchers at the Metsähovi Observatory have discovered these areas – called “radio lights” – in numerous solar zones. Usually these enlightenments have three explanations.
The first are coronal holes at the two poles of the Sun, which direct heat outward through solar winds; the second is the ejection of hot material from the surface of the Sun; and the third is areas where strong magnetic fields are detected.

However, scientists have found radio lighting in areas where none of these factors apply.
“The other sources used did not explain the reason for the lightening. We do not know what causes these phenomena. We need to continue our research, “said scientist Juha Kalunki.
The study of the sun’s minimum sun – the period during which the Sun’s magnetic field is weakest – revealed other new information.
Previously, scientists believed that the Sun’s behavior during these lows was passive, and so little research had been done on the activity of our nearest star during its quieter moments.
Instead, questions were raised about when the next active solar minimum would occur and how intense it would be.
Although it was previously thought that lows occur every 11 years, researchers no longer believe that this is the case.
“Solar activity cycles don’t always last exactly 11 years,” said Merya Tornikoski, one of the researchers in the new book.
“A new period of activity will not be identified while it is already going on. In any case, these observations of the quiet phase we are now analyzing are clear during the period when activity is lowest. We are now waiting for a new rise in activity.”
Each of the last four solar lows was also weaker than the previous one, leaving scientists confused about the reason for such a change.
The scientists’ research will be published in Solar Physics, and astronomers are reported to be systematically studying solar minima for the first time.
On Earth, solar minima can cause additional cosmic rays in the solar system, which hits the planet with X-rays and ultraviolet radiation.
In their worst solar storms caused during these periods, they can affect satellites, electrical networks and radio communications, as well as pose a danger to astronauts.
