The Multiscale Magnetospheric Mission (MMS), a space project consisting of 4 satellites launched by NASA 2015, discovered a magnetic explosion on Earth's night side, enabling a better understanding of the magnetic feedback phenomenon, according to an article published Thursday in the journal Science.

The mission was given the opportunity to get high-resolution images of our planet on the night side, a new perspective that gives NASA information about how magnetic reconnection works, "an energy conversion process that occurs in many astrophysical contexts. [en todo el universo], including the Earth's magnetosphere. "

This is the first time that researchers have been able to observe this phenomenon due to a stream of particles symmetrically oriented in the form of a tail which, according to the Science Alert portal, is a "calmer version" of the chaotic activity recorded in the solar side of the Earth's magnetosphere .

"The more we know about these feedbacks, the more we can prepare for external events that are possible from [de este fenómeno] around the earth or somewhere in the universe, "said Roy Torbert, deputy main researcher of MMS.

The scientists, who had already mapped the details of this phenomenon in this part of our atmosphere in October 2015, have now seen it as a comet on the dark side of the earth, giving them a new vision of the same as it reveals even flows of jets of high power electrons moving at speeds of more than 15,000 kilometers per second.

Earth's surface is protected from the constant rain of electrons and high-speed protons released from the sun through "a magnetic umbrella" whose "tissue twists and turns with energy as it draws the particles into it." The length of the channels in the loop "and finally returns to space , recalls Science Alert. In the event of a large accumulation of these particles, it may "cause chaos for networks and electrical systems".

The MMS launched on March 13, 2015 is a tetrahedral satellite formation aimed at gathering information about microfysics for magnetic feedback, acceleration of energetic particles and turbulence as well as processes that occur in many astrophysical plasma.
