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

“The Answer to the Great Question... Of Life, the Universe and Everything... Is... Forty-two,”
said Deep Thought, with infinite majesty and calm…“I checked it very thoroughly,” said 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 …

terrestrial rocks. By the year 1850, 18 elements had been identified in meteorites: carbon,
oxygen, sodium, magnesium, aluminum, silicon, phosphorous, sulfur, potassium, calcium …

The r-process, or the rapid neutron-capture process, of stellar nucleosynthesis is called for to
explain the production of the stable (and some long-lived radioactive) neutron-rich nuclides …

A giant impact between the proto-Earth and a Mars-sized impactor named Theia is the
favoured scenario for the formation of the Moon,,. Oxygen isotopic compositions have been …

The p-process of stellar nucleosynthesis is aimed at explaining the production of the stable
neutron-deficient nuclides heavier than iron that are observed up to now in the solar system …

Nucleosynthetic isotope anomalies are powerful tracers to determine the provenance of
meteorites and their components, and to identify genetic links between these materials. Here …

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type
(CI) chondrites are distinct from other carbonaceous chondrites, which has led to the …

Isotopic variations usually follow mass-dependent fractionation, meaning that the relative
variations in isotopic ratios scale with the difference in mass of the isotopes involved (eg …
