Sun's magnetic field is 10 times stronger than previously thought, finds a study that could potentially change the understanding of the processes taking place in the immediate atmosphere of the sun.
The study showed that the solar corona extends millions of kilometers above the surface, the size of 1400000 kilometers across – 109 times greater than on Earth – and 150 million km from Earth.
"Everything that happens in the outer atmosphere of the Sun is dominated by the magnetic field, but we have very little measurement of its strength and spatial characteristics," David Kuridze, a graduate student at Aberystwyth University.
Using the Swedish 1-m Solar Telescope at Roque de los Muchachos Observatory, La Palma in the Canary Islands, Kuridze studied particularly strong solar flare that erupted near the surface of the Sun September 10, 2017.
Solar flares with & # 39 are as bright flashes and occurs when magnetic energy that has accumulated in the solar atmosphere suddenly released.
"This is the first time we were able to accurately measure the magnetic field coronal loops, magnetic building blocks of the solar corona, which is a level of accuracy," said Kuridze.
Until now, the successful measurement of the magnetic field was not hampered by the weak signal of the solar atmosphere, which reaches the earth and decay information on the magnetic field, as well as limitations in the available instrumentation.
The magnetic field shown in a study similar to the typical refrigerator magnet and about 100 times weaker than the magnetic field occurring in the magnetic resonance imaging.
Nevertheless, they are still responsible for the content of solar plasma that make up the solar flares as 20,000 km above the solar surface.
These solar flares can lead to storms, which, if they hit earth form aurora – borealis.
They can also disrupt communications satellites and GPS systems, the researchers noted.
