Could cosmic radiation from a magnetic pole shift explain Neanderthal extinction? A new study from the University of Michigan has reignited a long-standing debate surrounding the mysterious extinction ...
The European Space Agency's Solar Orbiter, in collaboration with NASA, has captured unprecedented images of the Sun's south pole from 40 million miles ...
Around six hundred million years ago, our planet almost lost the invisible shield that keeps its surface hospitable. Earth’s magnetic field, generated by whirling molten iron deep below our feet, ...
What the magnetic field around Earth may have looked like during the Laschamps excursion, a time period between 42,200 and 41,500 years ago when the North and South magnetic poles went for a wander ...
It’s known that Earth had a magnetic field 3.7 billion years ago thanks to iron-rich rocks found in southwestern Greenland known as the Isua Greenstone Belt, which date to this time.
NASA has refocused its Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) launch date to no earlier than 2025 to provide more time for the mission crew to prepare. This ...
The main aim of this experimental investigation is to forecast the movement and possible shifts of the Earth's magnetic poles by utilizing machine learning (ML) techniques. With historical data and ...

Occasionally, the magnetic field’s north and south poles swap completely—a natural phenomenon that has taken place about 180 times in Earth’s history.
A magnetic shift 41,000 years ago triggered global auroras like the aurora australis. Credit: NASA Around 41,000 years ago, a powerful magnetic shift weakened Earth’s natural shield against space ...
Around 41,000 years ago, Earth’s magnetic field underwent a chaotic shift that temporarily weakened the planet’s natural protection from harmful solar radiation. A new study suggests that early Homo ...
A Magnetic Field in Crisis During the Laschamps excursion, Earth’s magnetic field weakened to just 10% of its current strength, while the magnetic poles shifted dramatically away from the geographic ...
