Yan said that the one-sided magnetic field could arise if Mars' inner core was liquid. In the study, published in the journal Geophysical Research Letters, the researchers used a computer simulation ...

“The logic here is that with no solid inner core, it’s much easier to produce hemispheric (one-sided) magnetic fields,” said Dr. Chi Yan, who is a research associate at the University of Texas ...

Molten Martian core could explain red planet's magnetic quirks Date: April 15, 2025 Source: University of Texas at Austin Summary: First ever supercomputer simulations of Mars with a fully molten ...

which then creates the magnetic field within the earth’s outer core. Therefore, this movement can be affected by the change in how the molten core is flowing. Reports state that a “tug-of-war” between ...

Earth’s outer core is made up of mostly molten iron, a liquid metal. Unpredictable changes in the way it flows cause the magnetic field around the Earth to shift, which then causes the magnetic ...

has demonstrated how Earth's magnetic field may be influencing internal flow, using what they describe as a Little Earth Experiment. Prior research has shown that Earth's inner core is essentially ...

Tom Howarth is a Newsweek reporter based in Bristol, U.K. His focus is reporting on nature and science. He covers climate change, biodiversity, extreme weather, zoonotic diseases and more.

The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago. When you purchase through links on our site, we may earn an ...

but scientists do suspect that “iron snow” falls on the Earth’s core. Now, a new study has modeled the dynamics in the lab and found that iron snow could make magnetic fields switch on and ...

Essentially, the study stated, the two-star system used to contain three stars, and one star swallowed up one of its companions, forming a highly magnetic core. The researchers suspect that the ...
