Of its three stable isotopes, oxygen 16 makes up 99.762 percent of oxygen on Earth, while heavier oxygen 17 accounts for just 0.038 percent, and the heaviest isotope, oxygen 18, makes up 0.2 percent.

Rare oxygen isotope detected at last — and it defies expectations Oxygen-28 might prompt physicists to revamp theories of how atomic nuclei are structured. By ...

The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists based on the first observation of their decay into oxygen-24 and three and four ...

The paper, titled Distinct oxygen isotope compositions of the Earth and Moon, may challenge the current understanding of the formation of the Moon.

Oxygen isotopes in some areas are not only controlled by air temperature and the amount of rainfall, but other complex factors that need to be studied more thoroughly, such as longer-term cycles.
