According to the scientists, their results are for a better and more accurate understanding of the process, that take place in the solar atmosphere, some of which can affect the earth.
Researchers from Aberystwyth University in Wales, the Queen's University of Belfast and other universities across Europe have discovered that the sun's magnetic field is about ten times stronger than previously thought
The scientists' findings published in the Astrophysical Journal were thanked by dr. David Kuridze and his team observing a particularly strong sun eruption on the sun's surface over a ten-day period in September 201
With high-resolution imaging spectropolarimetry of the telescope and the application of a combination of "certain favorable conditions" and a bit of luck, focusing just on the right volatile area of the sun when the solar flare hit, Dr. Ing. Kuridze and his co-workers an unprecedented measure of the actual strength of the magnetic field of the flare.
"Everything that happens in the outer atmosphere of the Sun is dominated by the magnetic field, but we have very few measurements of its strength and spatial properties," explained Dr. Kuridze. "These are critical parameters, the most important for the physics of the solar corona," added the scientist, pointing to the aura of the plasma that surrounds the Sun and other stars and extends millions of miles into space.
Focus on The solar flare enabled researchers for the first time to accurately measure the magnetic field of the coronal loops, the building blocks of the sun's magnetic corona, with such accuracy. Kuridze.
The scientists were limited by the weakness of the signal from the solar atmosphere, which actually reaches the Earth, and the relatively low power of artificial instruments. The magnetic fields were analyzed in the study by Dr. med. Kuridze et al. 100 times weaker than a typical hospital MRI scanner. Nevertheless, these readings are still strong enough to limit the solar plasma that makes up a solar flare to 20,000 km above the sun's surface.
Dr. Michail Mathioudakis, a professor at the Faculty of Mathematics and Physics at the University of Belfast, boasted that the study contains a "unique set of observations" that "for the first time provide a detailed map of the magnetic field in coronal loops." According to the scientist, the result will be the opening of "new ways of studying the solar corona". These findings, in turn, could alter the understanding of humanity for the processes in the immediate atmosphere of the Sun.
Solar flares can lead to magnetic storms that, when they reach Earth, produce the Northern Lights effect, also known as Aurora Borealis. As long as the flares are sufficiently intense, there is a risk that human-induced infrastructures cause significant damage. This applies to everything from spacecraft and satellite instruments in near-earth orbits to power grids on Earth. In 2011, the US National Academy of Science calculated that a repeat of a major solar storm like the one that struck Earth in 1859 could cause up to $ 2 trillion in initial damage and could take up to a decade to repair.
