Huge discovery
Yes it’s a very interesting discovery indeed. Took him years to figure it out it was real as well.
Wow! That has quite a lot of implications!
Such as !
How oxygen is formed…Basically everything astro looking for life. How our own life evolved on this planet. That’s pretty damn big.
Oh come on, what has Oxygen ever done for us?
Good point, I never thought about it like that… always like O this, O that. Never thinking about somebody else. Get the H outta here! Double time!
Terraforming other planets
The first bacteria/cells on Earth were likely not oxygen metabolisers. They lived in an anaerobic environment for a very long time.
Not to say that oxygen formed from non photosynthetic processes isn’t huge news.
Also there’s something deeper there, the energy potential of natural batteries that is interesting to me.
In the initially anaerobic atmosphere of Earth, the first energy-generating reactions presumably involved the breakdown of organic molecules in the absence of oxygen. These reactions are likely to have been a form of present-day glycolysis—the anaerobic breakdown of glucose to lactic acid, with the net energy gain of two molecules of ATP. In addition to using ATP as their source of intracellular chemical energy, all present-day cells carry out glycolysis, consistent with the notion that these reactions arose very early in evolution
One would hope that our inter planetary survival doesn’t involve billions of years of waiting 
Oxygen is pretty important in how our planetary chemistry exists today. At least at the gaseous level. Pretty cool how our entire understanding is now potentially learned upside down and how life could have evolved. Huge implications, especially for future prospects.
The dreaded redox. That part of the story just blows my mind, short circuits my brain if you will. Interesting that implications would go straight to other planets when this shows just how obviously we haven’t figured out the instruction manual on this one yet.
Huge implications everywhere, not just space. Evolution being a huge one as well. This type of discovery really hits at a more root type of situation, where so much discovery has been built on top of with the assumption its plant only. That’s pretty amazing and seemingly limitless thungs could now be re thought.
