New research published by the University of Texas Institute for Geophysics offers a compelling explanation for the strange ...

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

Scientists have known for a while that Mars currently lacks a magnetic field, and many blame that for its paltry atmosphere – ...

Learn about Mars' defunct magnetic field, which may have sustained life on the planet and covered only its southern ...

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

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

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 ...

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

A new study uses inversions of orbital gravity and magnetic field data to argue for the presence of ancient, long-lasting hydrothermal systems on Mars.

"The logic here is that with no solid inner core, it's much easier to produce hemispheric (one-sided) magnetic fields," Yan said. "That could have implications for Mars' ancient dynamo and ...
