For the first time, an international team of scientists has observed a series of seismic waves running through the Martian core.

These observations revealed that the Red Planet’s core is smaller and denser than previously estimated (with a radius of about 1,780 km to 1,810 km) – and consists of a completely liquid iron alloy with high proportions of sulfur and oxygen.

The discovery, made from measurements by NASA’s InSight probe, will provide a better understanding of how the planet originated and how it differs geologically from our own.

The research results have been published in the scientific journal Proceedings of the National Academy of Sciences.
