Wait... Did that article say confirmed photochemistry?

Yes why ? It's when the star winds interact with the planet athmospere and create new particuls

I guess, it sounds a lot like something photo synthesis would be classified under.

If by star winds you mean light

"concrete evidence" was the term used. However as they note photochemistry is just that. Light and chemicals. We should expect to see it anywhere we can see.

More like the pressure that photons creates as they travel.

Solar wind and presumably "star wind" conventionally refers to charged particles being lost from the corona of the star and traveling through space. This has nothing to do with photochemistry which involves light itself.

I know that. I was referring to the comment about star wind. Yes it's charged particles being released but photonic pressure plays a part also. Wasn't referring the chemistry but the physics.

Yeah, it is a hot gas giant planet with a high temperature of 900 °C, it's very unlikely to host any life.

Yes it would be inaccurate to say this powers photochemistry. As I pointed out.

Yes, just wanted to point out why someone might find the term an exciting discovery thinking it implies that when it does not.

The article explain it "concrete evidence of photochemistry – chemical reactions initiated by light hitting a planet's atmosphere." so he might just have read the keywords

This. It's interesting for sure, but can we stop being surprised that chemistry and physics are going to be all the same everywhere we look?

The "Atmosphere Composition" image in posted article has no reason to be in the article since (as usual) someone decided to use a thumbnail/downsized version which is worthless.

To actually see it :

Photochemistry is not photosynthesis as many seem to have assumed. Photochemistry happens on Titan nothing groundbreaking other than JWST can make this measurement over a greater distance than previously possible.
