The MSS, a space project composed of 4 satellites that were launched by NASA in 2015, detected a magnetic explosion on the night side of the Earth, which will allow a better understanding of the phenomenon of magnetic reconnection, according to an article published Thursday in the journal Science.
The mission had the opportunity to obtain high resolution images of the night side of our planet, a new perspective that provides NASA with information on the magnetic reconnection operation, "an energy conversion process that occurs in many astrophysical contexts. [en todo el universo]including the Earth's magnetosphere. "
This is the first time scientists have been able to observe this phenomenon thanks to a stream of symmetrically aligned particles in the form of a tail which, according to the Science Alert portal, is a "calmer version" of the chaotic activity recorded on the solar side of the magnetosphere from the earth.
"The more we know about these reconnections, the more we can prepare for external events that are possible from [de este fenómeno] around the Earth or anywhere in the Universe, "said Roy Torbert, deputy principal investigator for MMS.
Scientists, who had 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 view of the planet. the same because it reveals smooth flows of high energy electron jets that move at a speed of more than 15,000 kilometers per second.
The Earth's surface is shielded from the constant rain of electrons and high-velocity protons that are released from the Sun by means of a "magnetic umbrella," whose "tissue rotates and undulates with energy as it drags the particles into it. channels in loop "and finally, it returns to space, recalls Science Alert. In the case of a large accumulation of these particles, this could "cause the chaos of networks and electrical systems".
Launched on March 13, 2015, the MMS is a tetrahedral satellite formation that aims to gather information about the microphysics of magnetic reconnection, the acceleration of energetic particles and turbulence, as well as the processes that occur in many astrophysical plasmas.
