If you've never heard of a solar storm or geomagnetic storm, chances are you'll learn about those really quickly this weekend. Earth is under a severe G4 watch or geomagnetic storm watch for the ...

A geomagnetic reversal is a change in the orientation of Earth's magnetic field such that the positions of magnetic north and magnetic south become interchanged. The Earth's magnetic north pole is ...

Flares and coronal ejections shooting off from the Sun's surface struck the Earth overnight, causing a severe geomagnetic storm. It was the strongest such event in about 20 years, leading to stunning ...

New evidence suggests that high-energy particles from space known as galactic cosmic rays affect the Earth's climate by increasing cloud cover, causing an "umbrella effect". When galactic cosmic rays ...

One of the most interesting discoveries about Earth in the past few decades concerns the Earth’s magnetic poles. Paleomagnetic records show that the poles have flipped places 183 times in the last 83 ...

A study of the most recent near-reversals of the Earth's magnetic field by an international team of researchers has found it is unlikely that such an event will take place anytime soon. A study of the ...

A perfectly preserved ancient tree fossil has offered scientists a unique peek into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The impressive study paints a picture of ...

Non-reversing (superchrons) and reversing geodynamo states punctuate the Phanerozoic and Proterozoic 1, with reverse polarity superchrons during the early-mid-Ordovician (Moyero superchron) and during ...
