Scientists have long puzzled over why Mars, once protected by a global magnetic field like Earth, now shows only a magnetic ...

Uncover the mysteries of Mars' magnetic field, generated by a molten core, unlike Earth's solid core structure.

Mars' magnetic mystery may finally have a solution—scientists now think the Red Planet’s ancient magnetic field only existed ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the ...

Did Mars once have a full magnetic field in its ancient past like Earth does today, or was it lopsided and only covered ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously ...
