The side of Mercury we're seeing in the pic is quite cold

Im struggling to parse this. The picture of the sun with the tiny dot when compared with the artists impression you posted. It just wont click together. How can the sun appear so big from the telescope compared to mercury but be so small from mercury's perspective?

Edit. Actually i think it clicked. Mercury is so far from us and so smalkl that it appears like a small dot through that telescope even when zoomed in enough to see the sun that closley. Its actually still really far from the sun but our perspective and that flat picture makes it seem like its about to be consumed by the sun. If it was off to the side the distance would be more clear.

So more like this

You shouldn't stare too long at this photo with your naked eye or you'll go blind.

Puts in perspective how small Mercury is.

Right, I feel like no astronomer should be unsettled by just a picture of our solar system.

It doesn't exactly unsettle me, but pondering the mind-boggling scale of celestial bodies and the cosmos can certainly be... humbling, I guess?

I had a co-worker a while back who couldn't talk about the great scale of the universe cause he'd get freaked out. It didn't come up much, but when it did, he'd be like, "Please stop, it's stressing me out" so we'd change the subject.

You're not invited to my birthday party.

Less about size and more about size and relative distance. Think about being on Mercury and the entire sky is blazing sun - and yet it survives.

But pray to Joe Pesci, right? You pray to Joe Pesci, right?! RIGHT?

Wow. I was in middle school and had to do a creative writing assignment, and I wrote a science fiction short story set in a colony on that boundary of Mercury. I thought Mercury was tidal locked. I was praised for my creativity.

I was today years old when I found that Mercury is not tidal locked.

That was in the Red / Green / Blue mars trilogy, one of my favorites. Though I think I've seen the concept in other works as well.

Basically the temp difference between day / night caused contraction of the rail tracks, pushing the whole city forward so it was always just ahead of dawn.
