Experiments to simulate Mars’ core may explain the loss of its magnetic field. It has long been known that Mars once had oceans due in part to a protective magnetic field similar to Earth’s. However, the magnetic field disappeared, and new research may finally be able to explain why. Researchers recreated conditions expected in the core of Mars billions of years ago and found that the behavior of the molten metal thought to be present likely gave rise to a brief magnetic field that was destined to fade away.
Whether it’s due to science fiction or the fact that you can see it with your own eyes from Earth, Mars has captured the imagination of people for centuries...
