“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 ...

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 ...

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 ...

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

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 ...

One of these ride-along NASA efforts is the Athena EPIC (Economical Payload Integration Cost) SmallSat, which will ...

Click here to see them. The Kp index, which measures activity in Earth's magnetic field, is expected to peak during the weekend at 4.67, according to the NOAA's Space Weather Prediction Center.

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.
