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 ...

Astronomers detect molecular oxygen in space using the Herschel Space Observatory, revealing secrets of the Orion Nebula. , located about 1,500 light-years from Earth. This takes astronomers one step ...

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 ...

Finding oxygen in an exoplanet’s atmosphere is a clue that life may be at work. On Earth, photosynthetic organisms absorb carbon dioxide, sunlight, and water and produce sugars and starches for energy ...

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 ...

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 atom as its centerpiece, ...

The ice we blend into our frozen drinks is a complicated compound, riddled with strange molecular inconsistencies scientists still struggle to understand. Exploring the physics behind the odd ...

The Rosetta spacecraft has detected significant levels of molecular oxygen coming from Comet 67P/Churyumov-Gerasimenko in a discovery that has taken astronomers by surprise. This is the first comet ...

A team of chemists at the Korea Advanced Institute of Science and Technology has succeeded in pulling an oxygen atom from a molecule and replacing it with a nitrogen atom. In their study, published in ...
