Canyon has leaned into the adventure USP with this latest incarnation of the Grizl. The brand's PR material asks if ...

Earth’s magnetic field strength and atmospheric oxygen levels have oscillated in tandem for around 540 million years, according to a NASA-led study, pointing to a deep-Earth process that could knit ...

An international team, led by Instituto de Astrofísica e Ciências do Espaço (IA) researcher Ângela Santos, has made the first ...

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

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

Unlike Earth, the Moon doesn't have much of a magnetic field – and yet, a strange pile of rocks on the far side seems mysteriously magnetized.

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 ...

But the dynamo effect of the Moon’s small core (only about 90 miles [140 km] wide) could produce magnetic fields only one-tenth of that needed to magnetize these large surface regions.

Mars’ magnetic field was once generated by its dynamo, a mechanism shaped by currents within the planet’s liquid core (thought to be made of iron, sulfur, and hydrogen). The magnetic field would have ...

A planetary dynamo is a self-sustaining mechanism that generates a magnetic field, typically through movement in the molten metallic core. "We had no idea if it was going to explain the magnetic field ...

A dynamo magnetic field, like that of the Earth, is generated by the flow of liquid metal in the planet’s core. This field protects the planet’s atmosphere and water from solar wind erosion.
