Living things don’t need sunshine, the deep ocean thermal vents are crawling with life that does not rely on the sun either directly or indirectly

Thanks for explaining this. I didn't know that. I learned something new. I don't know if you can answer this question. This article is about the curiosity rover finding sun rays on Mars. How do sun rays affect Mars?

They don't affect Mars, they are an effect of Mars' atmosphere at sunset.
On Earth we have a lot of images of sun rays, light coming through clouds being visible in the air. But Mars only has a few cameras on it, so the chances of seeing sun rays is much less- it finally happened.
But it's not just about looks, it helps researchers better understand things such as Mars' atmospher or weather.
