This article reviews our current understanding of terrestrial planet formation. The focus is on
computer simulations of the dynamical aspects of the accretion process. Throughout the …

The formation of planetesimals, the kilometer-sized planetary precursors, is still a puzzling
process. Considerable progress has been made over the past years in the physical …

Saturn's moon Enceladus has an ice-covered ocean; a plume of material erupts from cracks
in the ice. The plume contains chemical signatures of water-rock interaction between the …

The VIRTIS (Visible, Infrared and Thermal Imaging Spectrometer) instrument on board the
Rosetta spacecraft has provided evidence of carbon-bearing compounds on the nucleus of …

Determining the source (s) of hydrogen, carbon, and nitrogen accreted by Earth is important
for understanding the origins of water and life and for constraining dynamical processes that …

We present a comprehensive evolutionary model of the Sun's protoplanetary disk,
constructed to resolve the" CAI storage problem" of meteoritics. We predict the abundances …

Chondrule-like objects and Ca-Al-rich inclusions (CAIs) are discovered in the retuned
samples from asteroid Ryugu. Here we report results of oxygen isotope, mineralogical, and …

Saturn's moon, Enceladus, is a geologically active waterworld. The prevailing paradigm is
that there is a subsurface ocean that erupts to the surface, which leads to the formation of a …

Aerogels are highly porous structures prepared via a sol‐gel process and supercritical
drying technology. Among the classes of aerogels, silica aerogel exhibits the most …

Context. We investigate the formation and evolution of comet nuclei and other trans-
Neptunian objects (TNOs) in the solar nebula and primordial disk prior to the giant planet …
