NASA has recorded a magnetic explosion on Earth – ElSol.com.ar – Diario de Mendoza, Argentina



The magnetosphere mission (MMS), a space project consisting of four satellites launched by NASA in 2015, identified a magnetic explosion on the night side of the Earth that would allow a better understanding of the phenomenon of magnetic connection, according to an article published Thursday in the journal Science.

The mission was an opportunity to obtain high-resolution images of the night side of our planet, a new perspective that provides NASA with information on the operation of the magnetic connection, "an energy conversion process that takes place in many astrophysical contexts. [en todo el universo], Including the Earth's magnetosphere. "

This is the first time that scientists have been able to detect this phenomenon, thanks to a stream of symmetrically aligned tail-shaped particles that according to the Portal "Scientific Alert" is a "more relaxed version" of the chaotic activity recorded on the solar side of the Earth's magnetosphere.

"The more we know about these connections, the more we can prepare for external events that can be [de este fenómeno] Around the globe or at any point in the universe, "said Roy Torbert, senior vice president of MMS.

The scientists, who have already mapped the details of this phenomenon in this part of our atmosphere in October 2015, now see it in the form of a comet on the dark side of the earth, which gives them a new vision of it because it reveals smooth currents of high- Moving at a speed of more than 15,000 kilometers per second.

Earth's surface is protected from the constant rain of high-speed electrons and protons released from the sun by a "magnetic umbrella" whose tissue cools and waves in energy as the particles are dragged into it, the length of the channels in the loop. In case of large buildup of these particles it can "cause chaos to networks and electrical systems."

"MMS", established on March 13, 2015, is a satellite tetrahedral array designed to collect information on the microfysics of magnetic reconnection, acceleration of energetic particles and vortex, and on processes occurring in many astrophysical plasmas.
