Note the theory in this release is the oxygen is from a mature star releasing heavier elements, not plant life.
I thought oxygen detection was extremely difficult, they must have better methods now.

- hnuser123456 2y agoOxygen detection on specific exoplanets is very difficult, unless the planet happens to pass between its star and Earth so we can see light passing through its atmosphere. Oxygen detection across an entire galaxy, not as hard.
- fph 2y agoTechnically, all oxygen is from stars. Plants merely recombine chemically already-existing oxygen.
- pixl97 2y agoOxygen detection in space isn't hard, the article in question seems to be an attempt at detecting oxygen on an exoplanet which is massively hard. Now, conversely, oxygen detection in galaxies/around stars is difficult for another reason. It doesn't want to remain free oxygen and will gladly bind with any other atoms/molecules it runs into. https://now.northropgrumman.com/what-happens-to-oxygen-in-space https://now.northropgrumman.com/what-happens-to-oxygen-in-sp...
