A new simulation suggests a massive asteroid impact may have briefly supercharged the moon's magnetic field, leaving behind ...

Where did the moon's magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft ...

A combination of a dynamo-generated magnetic field and massive impacts could explain the highly magnetized rocks in some ...

There have been proposed hypotheses as to how the Moon could have developed a core dynamo. For instance, a 2022 analysis suggested that in the first billion years, when the Moon was covered in molten ...

Deciphering the universe’s secrets is partly done through observation, but just as important are solid models of the forces ...

The record sheds light on the climate early humans experienced when they were spreading out of Africa. A tree-ringed African ...

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud ...

There should be rocks showing both impact shock and high magnetism located near the lunar South Pole on the far side of the ...

Earth's magnetic field was so weak it almost disappeared. Then, seemingly out of nowhere, complex life emerged.

The curious minds at What If imagine the strange world created by Earth possessing Jupiter's immense magnetic field.

A tree-ringed African lake has yielded a record of Earth's magnetic field spanning the past 150,000 years. A core of rock and sediment drilled from the bottom of Lake Chala, a picturesque crater ...
