The magnetic field of the sun, and not the sun itself, has just flipped upside down.
The star at the center of the Solar System fully flipped its north and south poles, reversed to reach the midpoint of Solar Cycle 24, the Independent reported.
To mark the event, NASA released the following visualization of the entire process that occurred over the course of eleven years.
The sun’s solar cycle or Solar Cycle 24 takes approximately 22 years to be completed. On Sunday, the first half was completed, the other half is yet to come.
Also, this is a phenomenon in which the sun changes its magnetic poles, not the geographical ones, so there’s nothing really catastrophic about the process. Neither will the reversal have any significant effect on the magnetic field of the Earth.
“As Earth orbits the sun, we dip in and out of the current sheet. Transitions from one side to another can stir up stormy space weather around our planet,” according to Stanford University solar physicist, Phil Scherrer.
"At the height of each magnetic flip, the sun goes through periods of more solar activity, during which there are more sunspots, and more eruptive events such as solar flares and coronal mass ejections," NASA’s Karen C. Fox told the Independent.
