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 ...

Although the magnetic field of Mars hasn’t been in effect for billions of years, the evidence it left behind may suggest that the planet’s core is entirely liquid. Magnetic imprints still exist on ...

The planet's once-strong magnetic field appears to have been limited to its southern hemisphere, the apparent result of a fully liquid inner core that differs from that of Earth ...

This had significant repercussions for the subsequent evolution of Mars. Without its global magnetic field, Mars could not ward off the solar wind that began stripping away its atmosphere ...

Did Mars once have a full magnetic field in its ancient past like Earth does today, or was it lopsided and only covered one-half of the planet? This is what a recent study published in Geophysical ...

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 ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic ...
