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 ...

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 ...

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 ...

At TU Wien (Vienna), it has become possible to control one of the most important chemical processes: switching oxygen molecules between a reactive and unreactive state. Oxygen atoms are highly ...

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 ...

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 ...

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 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 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 ...
