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.

The paper, titled Distinct oxygen isotope compositions of the Earth and Moon, may challenge the current understanding of the formation of the Moon. Previous research led to scientists to develop ...

One way to study this question is by estimating the thickness of the ancient atmosphere by looking at the presence of oxygen isotopes. Isotopes are versions of an atom, in this case, oxygen ...

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 ...
