Hi mukkin, as it happens, astronomy/astrophysics has been a lifelong interest of mine, since age 12, and that's quite a few decades now. I'd already read many detailed articles from before the internet made so many available, and adding in all since the internet, it's been...a lot. Altogether I guess it's closer to 10,000 articles I've read by now than 5,000. Some of those pretty technical and involved.
So, as soon as I saw this common idea written in the article (and repeated in quite a few popular science articles):
" They could easily find the oxygen in Earth’s air, a tipoff to the fact that this is a living planet. The oxygen betrays photosynthesis."
