The CHONS elements that constitute the outgassed atmosphere and exosphere have likely
been delivered by chondritic materials to the Earth during planetary accretion and …

Although we have a reasonable understanding of the physical and chemical conditions
required to support the growth and reproduction of organisms, we still have only a …

The origins of the giant planet satellites are debated, with scenarios including formation from
a protoplanetary disk, sequential assembly from massive rings, and recent accretion after …

Evaporation or freezing of water-rich fluids with dilute concentrations of dissolved salts can
produce brines, as observed in closed basins on Earth and detected by remote sensing on …

The tumultuous early era of outer solar system evolution culminated when Neptune migrated
across the primordial Kuiper Belt (PKB) and triggered a dynamical instability among the …

Ceres hosts notable aliphatic-organic concentrations, ranging from approximately 5 to> 30
weight% in specific surface areas. The origins and persistence of these organics are under …

Impacts into icy bodies often generate near‐surface melt chambers and thermal
perturbations that soften the ice. We explore the post‐impact evolution of non‐penetrating …

Ceres, the most water-rich body in the inner solar system after Earth, has recently been
recognized to have astrobiological importance. Chemical and physical measurements …

Small bodies are among the best tracers of our Solar System's history. A large number of
space missions to small bodies (past and future) offer a unique opportunity to use these …

Before acquiring highest-resolution data of Ceres, questions remained about the
emplacement mechanism and source of Occator crater's bright faculae. Here we report that …
