A group of astronomers from the George Mason
University has succeeded for the first time, relate a Coronal Mass
Ejection with solar plasma arc. The finding, published in Nature Communications,
can help predict when these violent
Phenomena take place, can cause serious damage to
the Earth.
Among all known solar phenomena, the Coronal
Mass Ejections (CME) is probably the greatest concern to scientists. Huge
masses of charged particles the Sun ejects without notice and in any direction,
including our planet. Burning clouds of radiation traveling millions of
miles. Per hour than regularly rammed earth and have the potential
to "fry", literally, our power grids and
communications, plunging us into a long period of darkness and silence.
As the years pass, astronomers and astrophysicists
are beginning to understand how these disturbing events arise and expect to be
able to predict in the future. Now a group of researchers led by Jie
Zhang, solar physicist at George Mason University, has just taken an important
step in relating the CME with another class of phenomena: the huge plasma
arc occasionally form on the surface the Sun to Zhang and his colleagues,
these structures could be the cause of flares and solar flares, and also the
root of the dangerous ejections of solar material.
Long since astronomers realized the existence of
huge emerging plasma arcs, as if by magic, from the solar
surface. These structures really huge, much bigger than our
planet (pictured, along with Jupiter and Earth), and possess strong
magnetic fields in spiral or tube, into which electric currents circulating
intense and a lot of solar material.
