NASA Scientists Discover Another Radiation Belt Around Earth

Around the Earth, at the height of Ecuador, there is a system of radiation rings that were discovered by James Van Allen in 1958. Named the “Van Allen Belt”, what is known about this system is that it is among a thousand and 60, 000 kilometers from the planet's surface, and where the northern and northern auroras occur.

Astronomers believe that radiation rings appear to interfere with the functioning of satellites and spacecraft, and even influence the health of astronauts. Moreover, until now it was believed that the Van Allen Belt was formed by only two rings, which remained stable and in position due to the terrestrial magnetic field.

Unprecedented phenomenon

However, according to NASA, two space probes sent to take measurements on radiation belts detected the presence of a third ring, which is probably a temporary formation involving the second ring. The space agency also revealed that the system appears to be much more malleable and active than previously thought and could undergo reconfigurations in response to emissions from solar flares.

The discovery of the third ring came by chance, when scientists decided to turn on a measuring instrument - the new Relativistic Electron Proton Telescope - before it was originally programmed, to be able to evaluate data collected in conjunction with other equipment (the SAMPEX probe) that would be deactivated soon. After just five days of monitoring, the team observed the formation of the third ring. Check out an animation that illustrates the Belt:

Scientists were so surprised at first that they even believed that the phenomenon could be a defect in equipment, but the third ring remained visible for four full weeks. According to NASA, the discovery may help scientists understand how and when solar storms can damage our planet, and the extent to which the Van Allen Belt protects the Earth or not.
