More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

As with any such correlation, one has to entertain the notion that said correlation might be spurious or indirectly related before assuming a strong causal link. Here it is for example known already ...

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, has always been abundant in Earth's crust, but elemental diatomic oxygen ...

Earth’s magnetic field feels permanent, but science tells a far more fragile story. Long before modern life emerged, the invisible shield protecting the planet from solar radiation weakened to a ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet's magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

Satellites will now be able to move without a single drop of fuel. A New Zealand start-up, Zenno Astronautics, has successfully tested a thruster that uses superconducting magnets to maintain ...
