#Computer recreates powerful solar flares ETH Zurich rightoriginal Studyposted by Barbara Vonarburg-ETH Zurich on September 26 2014physicists have used computers to model solar explosions
Hans Jurgen Herrmann a professor at the Institute for Building materials says solar flares were not the original focus of the work.
Similar patterns to those in solar flares can also be found in earthquakes avalanches or the stock market. olar explosions do not of course have any connection with stock exchange ratessays Hermann
In the case of solar flares the build up of magnetic energy is emitted in sudden bursts. The sun consists of hot plasma made of electrons and ions.
The affected solar area lights up as a solar flare. The radiation extends across the entire electromagnetic spectrum from radio waves and visible light to X-rays and gamma rays.
Observations suggest that the solar flares size distributions show a certain degree of regularity statistically speaking. vents can be arbitrarily large
However calculations based solely on plasma turbulence were also unable to reproduce the occurrence of solar flares in full.
and reached a breakthrough. e have been able to reproduce the overall picture of how solar flares occurthe researcher says.
which control the occurrence of solar flares. Demonstrating such temporal-energetic correspondences is the first step towards a prediction model.
It has become increasingly important to be able to understand the Sun#s magnetic activity as it is the changes in its magnetic field that are responsible for#space weather#phenomena including solar flares and coronal mass ejections.
#8th-century tree rings hint at close-range space blast A blast of radiation that hit Earth circa AD 770 may have been caused not by a solar flare but by the energetic debris from the collision of two nearby neutron stars.
There is nothing similar anywhere else in around 3000 years of tree ring records leading Miyake to suggest a massive solar flare as the cause.
and there is no historical record of such an energetic solar flare. The aurora would have been seen up to tropical latitudes says Valeri Hambaryan of the University of Jena Germany.
A Bright Flash From The Sun At 8: 30 p m. Eastern time yesterday a solar flare peaked on the surface of the sun emitting an intense burst of radiation.
The sun is currently undergoing a solar maximum a peak of activity that occurs about every 11 years making solar flares like this more likely.
