The isotopic composition of meteorites and terrestrial planets holds important clues about
the earliest history of the Solar System and the processes of planet formation. Recent work …

The isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC)
meteorites indicates that meteorite parent bodies derive from two genetically distinct …

Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2
spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide …

Presented here are the observations and interpretations from a comprehensive analysis of
16 representative particles returned from the C-type asteroid Ryugu by the Hayabusa2 …

Volatile and organic-rich C-type asteroids may have been one of the main sources of Earth's
water. Our best insight into their chemistry is currently provided by carbonaceous chondritic …

Geochemical and astronomical evidence demonstrates that planet formation occurred in two
spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …

Astronomical observations reveal that protoplanetary disks around young stars commonly
have ring-and gap-like structures in their dust distributions. These features are associated …

Comparing compositional models of the terrestrial planets provides insights into
physicochemical processes that produced planet-scale similarities and differences. The …

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

Europa likely contains an iron‐rich metal core. For it to have formed, temperatures within
Europa reached 1250 K. Going up to that temperature, accreted chondritic minerals—for …
