The mystery of Mars' magnetic field has puzzled scientists for decades. A new study proposes a surprising explanation for its current asymmetry. Researchers at the University of Texas simulated a ...

Though Mars lacks a global protective magnetic shield like that of the Earth, strong localized magnetic fields embedded in the crust appear to be a significant barrier to erosion of the atmosphere by ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Robyn Williams: Why is Mars so lopsided magnetically, and do you really need a dynamo with a planet ...

Berkeley – Though Mars lacks a global protective magnetic shield like that of the Earth, strong localized magnetic fields embedded in the crust appear to be a significant barrier to erosion of the ...

New data gleaned from the magnetic sensor aboard NASA’s InSight spacecraft is offering an unprecedented close-up of magnetic fields on Mars In a study published today in Nature Geoscience, scientists ...

Mars had a global magnetic field much earlier—and much later—in the planet’s history than scientists have previously known. A planet’s global magnetic field arises from what scientists call a dynamo: ...
