Light elements in the Earth's core
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 …

Origin of life-forming volatile elements in the inner Solar System
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 erosion of large primary atmospheres typically leaves behind substantial secondary atmospheres on temperate rocky planets
Exoplanet exploration has revealed that many—perhaps most—terrestrial exoplanets
formed with substantial H2-rich envelopes, seemingly in contrast to solar system terrestrials …

Vertically Resolved Magma Ocean–Protoatmosphere Evolution: H2, H2O, CO2, CH4, CO, O2, and N2 as Primary Absorbers
The earliest atmospheres of rocky planets originate from extensive volatile release during
magma ocean epochs that occur during assembly of the planet. These establish the initial …

Venus, the planet: introduction to the evolution of Earth's sister planet
Venus is the planet in the Solar System most similar to Earth in terms of size and (probably)
bulk composition. Until the mid-20th century, scientists thought that Venus was a verdant …
