I think about oxygen a lot more than I used to. This is because I am studying a chemical defense that turns ordinary oxygen, the same old stuff we obtain from breathing air – the same stuff that is ...

What’s the News: For the first time, astronomers have found molecular oxygen, which makes up about 20 percent of our air on Earth, in space. Using the large telescope aboard the Herschel Space ...

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 ...

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 ...

Using computer simulations, researchers have shown that the oxygen molecule (O₂) is stable up to pressures of 1.9 terapascal, which is about nineteen million times higher than atmosphere ...

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 ...

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 ...

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 ...

• 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 ...
