Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...
Solar magnetism is a fundamental driver of dynamic phenomena on the Sun, manifesting in cyclic variations such as sunspot activity, flares, and coronal mass ejections. Central to this process is the ...

Geophysicists Ran Simulations And Found That Earth's Liquid Core May Have Released a Magnetic Field in the Past
The generation of the magnetic field on Earth made scientists wonder if the process occurred in the earliest days of the planet. The magnetic field generation was explained by a mechanism known as the ...
Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...
Dynamo theory By Science News January 1, 1946 at 11:56 pm - More than 2 years ago Physicist Walter M. Elsasser and geophysicist Edward Bullard separately propose between 1946 and 1949 that Earth’s ...
Paleomagnetic measurements indicate that a core dynamo probably existed on the Moon 4.2 billion years ago. However, the subsequent history of the lunar core dynamo is unknown.Here we report ...
More than 50 years ago, NASA landed humans on the Moon — and we brought a piece of it back with us to Earth. That 22 kilograms of rock and dust collected by the Apollo astronauts transformed our ...
