Today NASA confirmed that the Sun has flipped its magnetic field and has began its 25th solar cycle. This means that the Sun has flipped its magnetic field 24 times since we have began keeping record. The magnetic reversal occurs every 11 years and despite what many tin-foil hatters would lead you to believe, this is totally natural.
In the video above NASA has illustrated how the process takes place, and provides a complete timeline of Suns magnetic field since 1997, the end of the 23rd Solar Cycle. Other than some increased Sun Spots, and a few more flairs than normal, NASA says that we should not worry too much about the poles reversal.
