Scientists from multiple institutions have found that Mars likely never developed a solid inner core during its early history. This new research, published in Geophysical Research Letters ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

Beneath the mantle is a liquid iron outer core and solid iron inner core. Because Earth and Mars are both rocky planets, and might have even had similar surface conditions billions of years ago ...

while the inner core is solid and mostly made of iron. The scientists say it is possible that Mars’ lower mantle may also be molten, which would affect the size and shape of the core.

However, the team from the University of Science and Technology of China and the University of Texas at Austin believe they have found preliminary evidence of a solid inner core within Mars ...

Data from NASA’s Mars InSight mission suggests that its center is more decadent than expected. Rather than one single, sizable liquid iron core, there’s evidence that it's much smaller but ...

Yan said that the one-sided magnetic field could arise if Mars' inner core was liquid. In the study, published in the journal Geophysical Research Letters, the researchers used a computer simulation ...

The core of Mars can look bigger than it actually is because ... rippled through Martian rock to yield insights on the planet's inner structure. A trio of studies in 2021 based on those scans ...

which allows the inner core to rotate at a different speed from the rotation of the Earth itself. With a radius of almost 2,200 miles, Earth’s core is about the size of Mars. It consists mostly ...
