Not the centre of the Earth that Jules Verne saw

10 February 2022

The long held notion that the centre, or core, of our planet consists of solid iron, may have been up-ended by a recent study suggesting Earth’s inner core is made up of a solid iron sublattice and liquid-like light elements:

A joint research team led by Prof. HE Yu from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) has found that the inner core of the Earth is not a normal solid but is composed of a solid iron sublattice and liquid-like light elements, which is also known as a superionic state. The liquid-like light elements are highly diffusive in iron sublattices under inner core conditions.

Well that differs somewhat from nineteenth century French author Jules Verne’s depiction, in his 1864 novel Journey to the Center of the Earth.
