Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Beneath the bogs of New Zealand’s Northland is a massive Ngāwhā kauri, living from 41,000 to 42,500 years ago, which gives an isolated, unbroken record of a period when Earth’s magnetic field declined ...

New NASA research demonstrates that 540 million years of Earth’s magnetic field changes have corresponded to surface habitability.

Scientists believe the Sun’s magnetic field could reverse within our lifetime, a natural cycle that occurs roughly every 11 years. While this solar polarity shift is not dangerous, it can impact space ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

Never before seen pictures will help scientists learn how the Sun's activity changes from stormy to quiet periods ...

The reversal of the Sun's magnetic field is a gradual process, without a precise moment of flipping. It spans a period of one to two years, or even more, as observed during the previous solar cycle, ...

As well as a few temporary reversals, the Earth's magnetic field – just like the Sun – can flip over long timescales. During the Brunhes–Matuyama reversal, the magnetic north could have been ...

Scientists track the Earth's magnetic field using local measurements, orientation, and magnitude, as well as models. The north magnetic pole has migrated approximately 600 miles since 1831, with ...

While the north magnetic pole moving a little bit isn't a big deal, a reversal could have a big impact on Earth's climate and our modern technology. But these reversals don't happen instantaneously.
