Astronomers have detected molecular oxygen in another galaxy for the first time. The discovery is only the third sighting of O2 beyond our solar system.

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 ...

What role can the relationship between oxygen (O2) and ozone (O3) in exoplanet atmospheres have on detecting biosignatures?

Their results showed that modern Mars could support liquid environments with enough dissolved O2 to support oxygen-breathing microbes across the planet.

As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the ...
