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



Multiscale Magnetospheric Mission (MMS), a cosmic project consisting of 4 satellites initiated by NASA in 2015, has detected a magnetic explosion on the night side of the Earth, which will allow better understanding of the magnetic re-connection phenomenon, according to an article published on Thursday in the journal Science.

The mission had the opportunity to obtain high resolution images of the night side of our planet, an innovative perspective that provides NASA with information on the magnetic reconstruction of the energy conversion process that occurs in many astrophysical contexts. [en todo el universo]including the Earth's magnetosphere. "

For the first time, scientists have been able to observe this phenomenon thanks to the stream of symmetric tail-shaped molecules, which, according to the Science Alert portal, is a "quieter version" of the chaotic activity recorded in the solar side of the Earth's magnetosphere.

"The more we know about these reconnections, the more we can prepare for external events that are possible [de este fenómeno] around the Earth or at any point in the Universe, "said Roy Torbert, deputy chief investigator at MMS.

Researchers who have already mapped the details of this phenomenon in this part of our atmosphere in October 2015, now saw it in the shape of a comet on the dark side of the Earth, giving them a new vision the same, as it reveals smooth jets of high-energy electrons moving at speeds above 15,000 kilometers per second.

The surface of the Earth is protected from the continuous rain of high velocity electrons and protons, which are released from the Sun by means of a "magnetic umbrella" whose "tissue twists and waves with energy as it pulls the particles into it, the length of the channels in the loop" and finally returns to space, remembers Science Alert. In the case of high accumulation of these particles, this can cause "chaos for networks and electrical systems".

Launched on March 13, 2015, MMS is a formation of tetrahedron satellites, which aims to gather information about magnetic resonance microfiruses, acceleration of energy particles and turbulence, as well as processes occurring in many astrophysical plasmas.
