“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 million years ago,” the authors wrote. “Our findings suggest unexpected strong ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other ...

For 540 million years, Earth’s magnetic field and atmospheric oxygen levels have danced in sync — and NASA scientists just ...

For more than 100 years, scientists have puzzled over whether the Earth’s magnetic field had already been generated stably ...

Earth’s oxygenated atmosphere and magnetic field make life possible, but scientists have discovered that there’s a hidden link between the two that’s stronger than we originally imagined.

Researchers are on firmer ground when it comes to the physiological impacts of increased UV radiation. With the weakened ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a ...

Scientists have long known that Earth’s magnetic field has not been a constant shield. Now, new interdisciplinary research—recently published in Science Advances shows that a major geomagnetic event, ...

The strength of Earth’s magnetic field seems to rise and fall hand-in-hand with the abundance of oxygen in its atmosphere, a study of geological records spanning the last half billion years has ...

The Earth’s magnetic field has been weakening for 2,000 years, and that trend continues today, leading some to worry that it may be heading for a reversal. Although the idea of an impending magnetic ...
