Sun’s magnetic field will reverse in the coming months
In the next three to four months, the sun’s magnetic field, which bathes the Earth and all the planets of the system, complete polarity reversal, a process that occurs every eleven years, the space agency reported today U.S. NASA.
“This change will impact in the entire solar system,” said solar physicist Todd Hoeksema, Stanford University, in California, speaking for NASA.
reverse polarity north-south pass and vice versa occurs at the culmination of each solar cycle , when the sun’s inner magnetic reorganizes.
During this phase, which physicists call Solar Max , rashes can increase energy cosmic rays and ultraviolet radiation reaching the Earth, and this can interfere with radio communications and affect global temperature .
Hoeksema is director Wilcox Solar Observatory at Stanford, one of the few in the world studying the magnetic fields of the Sun and have observed this phenomenon since 1976, a period in which investments have been three. Phil Scherrer, another solar physicist at Stanford, said that what happens is that “the Sun’s polar magnetic fields weaken, remain at zero, and then emerge again with the opposite polarity.’s A normal part of the solar cycle.”
solar magnetic influence, known as the heliosphere , extends billions of miles beyond Pluto, and even capture the Voyager probes, launched in 1977 and now hover around the threshold of interstellar space.
