Data collected by the Swarm satellites reveals that the Earth’s magnetic field has changed significantly during the past six months.

Over the past six months, the Earth’s magnetic field has been weakening 10 times faster than in previous years, reports the European Space Agency (ESA). The recent changes may indicate that the Earth’s magnetic poles are about to flip.
The magnetic field, which has been described as a huge bubble that protects the Earth from incoming cosmic radiation and solar winds, is always changing and ESA’s Swarm mission has been tracking these fluctuations since November 2013.
