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, its ...

New research published by the University of Texas Institute for Geophysics offers a compelling explanation for the strange nature of Mars’ ancient magnetic field. The study suggests that the Red ...

The core of the Red Planet may be filled with sulfur. New experiments have shown that the core of Mars formed much faster than Earth's core, thanks to molten iron and nickel sulfides seeping down ...

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, is why this ...
