Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients
to build habitable worlds like Earth, but their origin and evolution on terrestrial planets …

The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

The formation of planetesimals is expected to occur via particle-gas instabilities that
concentrate dust into self-gravitating clumps,–. Triggering these instabilities requires the …

Little is known about the origin of the spectral diversity of asteroids and what it says about
conditions in the protoplanetary disk. Here, we show that samples returned from Cb-type …

Direct links between carbonaceous chondrites and their parent bodies in the solar system
are rare. The Winchcombe meteorite is the most accurately recorded carbonaceous …

Our understanding of planet formation has been rapidly evolving in recent years. The
classical planet formation theory, developed when the only known planetary system was our …

We demonstrate that the deep volatile storage capacity of magma oceans has significant
implications for the bulk composition, interior, and climate state inferred from exoplanet mass …

The nucleosynthetic isotope dichotomy between carbonaceous (CC) and non-
carbonaceous (NC) meteorites has been interpreted as evidence for spatial separation and …

The formation of super-Earths, the most abundant planets in the Galaxy, remains elusive.
These planets have masses that typically exceed that of the Earth by a factor of a few …

Determining the provenance of volatile elements in Earth is key for understanding the
processes that led to its formation as a habitable planet. We show that the moderately …
