Researchers have now found evidence that double ionised sulphur dioxide contribute to the formation of oxygen molecules. This could, in particular, explain the presence of oxygen in sulphur ...

Precision measurements on the oxygen formation in stellar helium burning use gamma-beams and a Time Projection Chamber. In the newly developed method, scientists shine gamma-ray beams, such as from ...

Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years.

A never-before-seen image of individual oxygen atoms dissolved in water has been captured.
