Historically, Earth's North and South magnetic poles have flipped every 200,000 or 300,000 years. However, the last flip was about 780,000 years ago, meaning our planet is well overdue. The latest satellite data, from the European Space Agency's Swarm trio which monitors the Earth's magnetic field, suggest a pole flip may be imminent. The satellites allow researchers to study changes building at the Earth's core, where the magnetic field is generated. Their observations suggest molten iron and nickel are draining the energy out of the Earth's core near where the magnetic field is generated. While scientists aren't sure why exactly this happens, they describe it as a "restless
