Scientists from the University of Colorado in Boulder are sounding the alarm that the Earth’s magnetic poles are showing signs of reversing. Although the pole reversal, in and of itself, isn’t unprecedented, the solar winds that would take out the power grid and make parts of the globe uninhabitable could cause widespread disasters. The Earth has a fierce molten core that generates a magnetic field capable of defending our planet against devastating solar winds. This magnetic field is vital to life on Earth and has weakened by 15 percent over the last 200 years. This protective field acts as a...

A magnetic field shift is old news. Around 800,000 years ago, magnetic north hovered over Antarctica and reindeer lived in magnetic south. The poles have flipped several times throughout Earth's history. Scientists have estimated that a flip cycle starts with the magnetic field weakening over the span of a few thousand years, then the poles flip and the field springs back up to full strength again. However, a new study shows that the last time the Earth's poles flipped, it only took 100 years for the reversal to happen. The Earth's magnetic field is in a weakening stage right now....

NEW DELHI: A special event is about to occur in our sun, and it could impact our lives. The magnetic poles of the sun — which are like the ends of a giant bar magnet — are about to flip, that is, the polar north will become the polar south and vice versa. According to scientists at the Wilcox Solar Observatory at Stanford University , the sun could be barely two to three months away from this magnetic field reversal. The change is periodic, taking place once every 11 years or so. The flip also corresponds with peak activity during...
