Ganymede is not only Jupiter's largest moon, but also the largest in our solar system and one of the few that hosts a massive ...

Earth’s inner core solidified sometime after 565 million years ago — just in time to not only save the planet’s protective magnetic field from imminent collapse, but also to kick-start it into its ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are directly influencing our planet's magnetic field in ways we're only beginning ...

A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth’s core, 1,800 miles underground. The magnetic field strength ...

A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth’s core, 1,800 miles (2,900 kilometers) underground. The ...

Annual to decadal changes in the earth’s magnetic field in a region that stretches from the Atlantic to the Indian Ocean have a close relationship with variations of gravity in this area. From this it ...

Researchers have shown that turbulence, random motion that takes place in the molten metal in the Earth's core, makes a contribution to our planet's magnetic field. To obtain this result, they modeled ...
