Uncovering the Secrets of Mars' Core: New Study Reveals Differences with Earth

Seismic waves have been detected traveling through the core of Mars for the first time, revealing details of the composition of the Red Planet's heart. The seismic data was collected by an international team of researchers using NASA's InSight Mars lander and it reveals the Martian core to be composed of a completely liquid iron-alloy core with high percentages of sulfur and oxygen. This grants a better understanding of how Mars formed in the infant solar system around 4.6 billion years ago and illustrates some of the key geological differences between the Red Planet and Earth, which may ultimately help explain why Earth can support life but Mars cannot.
