'Marsquakes' measured by NASA's InSight rover and an experiment to recreate the conditions thought to exist in the Martian core could reveal how the planet formed. Researchers from the University of Tokyo have been studying the seismic properties of iron-sulphur - thought to be the substance at the core of Mars. Dr Nishida added: 'Taking our results, researchers reading Martian seismic data will now be able to tell whether the core is primarily iron-sulphur alloy or not. 'For example, if Mars' core includes silicon and oxygen, it suggests that, like the Earth, Mars suffered a huge impact event as it formed. 'We needed to know the seismic properties of the iron-sulphur alloy thought to make up the core of Mars.'
