New images reveal powerful vortices on the surface of our star, a phenomenon that has never been observed before. According to researchers, these movements are created by the twisting and twisting of the Sun's magnetic field as a result of the movement of very hot gases.
This constant rotation is one of the main mechanisms that generates large bursts of energy, creating so-called “space weather.” These phenomena can affect electrical grids, satellites, communication systems, and even endanger astronauts in space.
"The Sun is the source of all this energy and space weather," said Dr. David Boboltz of the US National Solar Observatory (NSO). According to him, higher-resolution images will help scientists better understand the processes occurring on the Sun and, in the future, more accurately predict space weather.
The discoveries, published in the scientific journal Nature, were made possible thanks to the Inouye Solar Telescope, built on a mountaintop in Hawaii, where atmospheric conditions are ideal for astronomical observations.
Focusing on the Sun's surface, the researchers recorded tiny rotating vortices. NSO astronomer Dr. David Kuridze explained that these movements accumulate magnetic energy, which can then be released in the form of powerful solar flares.
What did scientists discover?
The observed phenomenon is known as the Kelvin-Helmholtz instability, which occurs when two layers of hot gases move at different speeds past each other, creating spiral vortices. A similar process occurs in the oceans, where small ripples can grow into large waves.
According to the researchers, this discovery helps explain how energy is transported to the upper layers of the solar atmosphere and why the Sun's surface reaches such high temperatures.
When the accumulated energy becomes large enough, it can be released in the form of solar flares or massive explosions of coronal material, which are among the main phenomena affecting space weather.
Scientists emphasize that, in addition to its practical importance for protecting technologies on Earth, the Sun remains an irreplaceable “natural laboratory” for studying the fundamental laws of physics. They recall that the first experimental proof of Albert Einstein’s theory of general relativity was achieved thanks to observations of a solar eclipse.
