Constraining the core's composition is essential for understanding Earth accretion, core
formation and the sustainment of Earth's magnetic field. Earth's outer and inner core exhibit …

Seismic images of Earth's interior reveal two massive anomalous zones at the base of the
mantle, above the core, where seismic waves travel slowly. The mantle materials that …

Hydrogen is one of the possible alloying elements in the Earth's core, but its siderophile
(iron-loving) nature is debated. Here we experimentally examined the partitioning of …

There is a long-standing debate regarding the origin of the terrestrial planets' water as well
as the hydrated C-type asteroids. Here we show that the inner Solar System's water is a …

The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

Proxima b is a planet with a minimum mass of 1.3M⊕ orbiting within the habitable zone (HZ)
of Proxima Centauri, a very low-mass, active star and the Sun's closest neighbor. Here we …

The Earth's core is about ten per cent less dense than pure iron (Fe), suggesting that it
contains light elements as well as iron. Modelling of core formation at high pressure (around …

Seismic recordings made during the InSight mission suggested that Mars's liquid core would
need to be approximately 27% lighter than pure liquid iron,, implying a considerable …

Constraints on the composition of Mars principally derive from chemical analyses of a set of
Martian meteorites that rely either on determinations of their refractory element abundances …

Earth's global magnetic field arises from vigorous convection within the liquid outer core.
Palaeomagnetic evidence reveals that the geodynamo has operated for at least 3.4 billion …
