Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature ...

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 ...

Mars' core formed at a surprising speed, much faster than Earth's. Recent experiments reveal the key role of iron and nickel sulfides in this process. Planets like Mars are structured in distinct ...

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 ...
