In a nutshell Mars likely never developed a solid inner core during its early history, meaning its magnetic field was generated by a fully molten core, unlike Earth’s layered core structure.

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving life a longer window to take hold on the Red Planet.

The history of magnetism on Mars remains a critical field of study since it is closely tied to the planet’s potential capacity for life billions of years ago. Mars’ magnetic field was once generated ...

New discoveries by NASA's Curiosity Mars rover may not only explain why the Red Planet is a dry, lifeless desert, but that it ...

If Mars' core is molten now, it almost certainly would have been molten 4 billion years ago when Mars' magnetic field is known to have been active, Stanley said. To test the idea, the researchers ...

The aurora on Mars has been captured in a photograph for the first time. Elise Wright Knutsen, at the University of Oslo, has been checking solar ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

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 ...
