Abstract: Magnetocardiogram (MCG) requires a near-zero magnetic environment, which cannot be achieved by passive shielding structure, and needs to be combined with active compensation to reduce ...

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.

Here’s what you’ll learn when you read this story: The Earth’s magnetosphere protects life from deadly space radiation, but many aspects of its function remain a mystery. Scientists have long believed ...

It would be an understatement to say that the Earth's magnetic field is important. It's one of the reasons we're able to live on this rock tumbling through space, and it also gives us the gorgeous ...

A major dip in the Earth’s magnetic field over the South Atlantic has been puzzling scientists for over a century. An international team of researchers analyzed data collected by the European Space ...

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 ...

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 ...

The magnetic field in 2025. Image credits: ESA. A notorious weak spot in Earth’s magnetic shield is growing larger and weaker. This is the conclusion of a new analysis of eleven years of ...
