Ancient Moon dust, meteorite traces and Apollo samples are helping NASA scientists rethink where Earth’s water truly came ...

Observations of nearby red dwarf stars reveal rare carbon and oxygen isotopes, offering direct evidence of stellar nucleosynthesis and the chemical evolution of the Milky Way.

Oxygen isotopes data enable researchers to look far back into the geologic past and reconstruct the climate of the past. In doing so, they consider several factors such as ocean temperature and ice ...

Triple oxygen isotope research has emerged as a powerful tool to enhance our understanding of hydrological processes and past climate variability. By simultaneously analysing δ18O, δ17O, and the ...

Scientists have performed a micro-probe analysis of the core and outer layers of a pea-sized piece of a meteorite some 4.57 billion years old to reconstruct the history of its formation, providing the ...

Göttingen University researchers analysed oxygen isotopes from corals, like this Acropora coral, to expand the uses of the “triple oxygen isotope” method and help measure temperatures from the past ...

NASA research using Apollo lunar regolith data refines the Moon’s impact record and places limits on meteorite contributions to Earth’s water over geologic time.

Scientists at The University of New Mexico have found that the Earth and Moon have distinct oxygen compositions and are not identical in oxygen as previously thought according to a new study released ...
