The telescope muons in GRAPES-3, located at the Laboratory of Cosmic Rays from the TIFR in Ooty (India), detected on June 22, 2015 an explosion of galactic cosmic rays that produced a crack in the magnetic shield of the Earth, reports the scientific journal ‘Physical Review Letters’. The incident occurred when the solar corona expelled a huge cloud of plasma that hit our planet.
Moving at a speed of 2.5 million miles per hour, the same compressed the magnetosphere of 11 to 4 times the radius of the Earth and triggered a strong geomagnetic storm. The expulsion of cosmic rays from about 20 GeV lasted two hours, and the impact of the outbreak was felt in many countries located in high latitudes, where there were blackouts of radio signal, precise to the portal Phys.org.
The earth’s magnetosphere protects the planet against the flow of solar rays and cosmic, and the impact of the radiation energy of high intensity. The data provided by the telescope indicate that the onset of a magnetic reconnection caused a temporary break in the magnetic shield of the Earth and the crack allowed the entry into the atmosphere of particles of galactic cosmic rays of lower energy. The magnetic field twisted these particles around 180 degrees, from the next day until the next night, where they were detected by the telescope GRAPES-3 as an explosion.
The experts argue that this fact indicates “the weakening transient, the magnetic shield of the Earth” and can contribute to a “better understanding of the supertormentas that could cripple you in the future, the technology infrastructure” in the planet and also put at risk the lives of astronauts that are in space.
