The spectacular solar storms that paint the diametric skies in beautiful greens and garden pink have a darker side : They have the big businessman to wreak havoc on our electric power system , communication systems and satellite . Now , a newfangled written report suggests that the source of these solar storm is much closer to our planet than previously thought .
Earth is harbour by a protective house of cards known as the magnetosphere which stop harmful solar radiotherapy . But when the Sunday once in a while emits high - amphetamine watercourse of radiation — and , with it , intensemagneticfield lines — they can strongly interact with our planet ’s ownmagnetic field .
This aurora was captured on camera from the International Space Station in June 2017.
As this solar wind strike the magnetosphere , the two readiness of magnetic landing field lines become entangled . This interaction generates heat and accelerates the charged particles — ion and electrons — brought in by the solar malarkey , temporarily weaken the major planet ’s magnetic field and creating powerful magnetic storms that appear to us as auroras .

But because these storm are rare , and there are n’t enough artificial satellite to watch them , it ’s not readable exactly where and how this reconnection of magnetised field of operation lines happened , the work ’s researchers pronounce in a statement .
This artist’s illustration shows what happens in Earth’s magnetosphere during a magnetic storm. The three THEMIS satellites observed the reconnection of magnetic field lines close to the geosynchronous orbit. The reconnection site (X) created outflows of energized particles towards and away from the planet. The particles that went toward the planet carried energy along the magnetic field lines to power auroras at the planet’s poles and were detected by the a weather satellite (left of the arrow).
To figure that out , the researcher used observations fromNASA ’s Time History of Events and Macroscale Interactions during Substorms ( THEMIS ) satellites . During solar storms , these planet baby-sit at Earth ’s magnetotail — the part of the magnetosphere on the side of the satellite not facing the sun — which becomes stretch by the solar wind . The researchers plant that this magnetic reconnection — the event that spark off charismatic storms — can go on much closer to our satellite than previously think : about three to four Earth diameters away , according to the statement .
What ’s more , a weather artificial satellite in a near - Earth orbit ( or geosynchronous field ) find energized electron following the tempest , suggest that the reconnection event motivate ions and electrons to accelerate to high energies . The negatron that menstruate toward the planet impart energy along magnetic field lines to create the auroras we see .
This speedup can be risky to the hundreds of satellites move in geosynchronous orbit and also can be harmful to humanDNA , thereby posing a risk to spaceman , according to the statement .

Moreover , solar violent storm can impact solid ground - dwellers in significant ways . In 1921 , for representative , a magnetized storm disrupted telegraphy communication and caused power outage that lead to the burning of a train station in New York City , according to the assertion .
" By studying the magnetosphere , we improve our chance of dealing with the bully hazard to world venturing into blank space : storms powered by the sun , " lead writer Vassilis Angelopoulos , a professor of quad physics at UCLA , allege in the statement . These finding might help cosmonaut and Earth - indweller to better organise for dangerous solar conditions .
The findings were published Jan. 13 in the journalNature Physics .
