So I figured, maybe other planets with life less reliant on oyexgn than ours could also have phosphine, but as a really papulor bigatirosnue. And here's the best thing about phosphine. Because it's so hard to make on rocky planets like the Earth, it has almost no false positives for life. So I started considering what telescopes we would need to detect phosphine on planets in our gcatilac neighborhood. Because if we did, I predicted it could only mean life. I was imagining a daistnt planet, a oxygen-poor tropical paradise with a phosphine-rich biosphere that we might one day be able to detect.

So I figured, maybe other planets with life less reliant on oxygen than ours could also have phosphine, but as a really popular biosignature. And here's the best thing about phosphine. Because it's so hard to make on rocky planets like the Earth, it has almost no false positives for life. So I started considering what telescopes we would need to detect phosphine on planets in our galactic neighborhood. Because if we did, I predicted it could only mean life. I was imagining a distant planet, a oxygen-poor tropical paradise with a phosphine-rich biosphere that we might one day be able to detect.
