A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new ...

A series of observations between 2017 and 2021 suggest the supermassive structure’s magnetized plasma is more dynamic than ...

The polarization pattern around M87* — the first black hole to be directly imaged by the Event Horizon Telescope — has changed direction, and scientists aren't sure why.

Images taken of the Universe's most photogenic black hole over time reveal strange and exciting changes in its magnetic field.

Ancient bricks may be key to understanding Earth’s variable magnetic fields. Scientists examined the iron oxide levels of 3,000-year-old bricks to understand the level of magnetism the bricks were ...

Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.

The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years. This has sparked many questions and concerns about the implications of such ...

NASA's GRACE satellite detected a large gravity anomaly over the Atlantic Ocean. Meanwhile, Earth-based observatories saw a ...

A recent study reveals dynamic transformations in Earth's lower mantle, impacting both earthquakes and the magnetic field. GRACE satellites detected a ...

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 ...

In 2007, something strange happened over the eastern Atlantic Ocean. According to satellites orbiting Earth, our planet's ...
