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

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

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 ...

Our magnetic field provides some protection from the onslaught of particles from the solar wind and cosmic rays from deep space. During a pole reversal, the field weakens, although it doesn’t ...

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

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 ...

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years, which ...

NASA has detected a mysterious weakening in Earth’s magnetic field over South America, here’s what it means for satellites and our planet.

As we witness the detrimental effects of climate change, the need for a rapid shift to renewable energy is only becoming more ...

The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity ...
