Scientists have discovered a new way to make molecular oxygen (O2) from carbon dioxide (CO2) -- no green plants involved. Their findings could alter our understanding of the Earth’s early atmosphere ...

Earth's atmosphere wasn't always full of life-giving oxygen — it was once a choking mixture of carbon dioxide and other gases, more like the atmosphere of Mars or Venus. It's widely believed that the ...

For the first time, astronomers have found molecular oxygen — the same gas humans need to breathe — in a galaxy outside the Milky Way. Oxygen is the third most common element in the cosmos, after ...

Colorado State University chemists have achieved a new feat in the realm of chemical design and synthesis: They’ve helped create the first example of a synthetic molecule, with an asymmetric oxygen ...

Chemists have synthesized the first stable molecule whose chirality is solely attributed to a stereogenic oxygen, according to a new study (Nature 2023, DOI: 10.1038/s41586-023-05719-z). Though carbon ...

The European Space Agency's Rosetta mission observed molecular oxygen (O2) emanating from Comet 67P/Churyumov-Gerasimenko. New Caltech research reveals that comets can naturally produce molecular ...

THE known spectrum of the neutral oxygen molecule consists of two well-known band systems, both of which occur in absorption, and arise from the normal state of the molecule. One of these systems, ...

• The structure of the red oxygen ε-phase formed under pressures above 10 GPa has been determined. • Discovery of an O 8 cluster, which is a new conformation of oxygen following ozone. The solid ...

The European Space Agency’s Rosetta spacecraft saw material and gases — including oxygen — erupt off the surface of Comet 67P/Churyumov-Gerasimenko. Space is an inhospitable place. For now, when ...
