I'll tell you what's definitely unsettling;
The fact that if you kiss a mirror, you'll only ever kiss yourself on the lips.

My favorite fun astronomy fact is that a transit like this (Venus, but still) is how we managed to figure out our distance to the Sun in the 1700s
I bet it's hot there.
The side of Mercury we're seeing in the pic is quite cold
I tried wiping the dust off my screen 😭
So conditioned that NDT is talking bullshit and people dunking on him that I had to read it a couple of times to understand it.
No, you morons! That's your thumb with the close ad X under it.
I mean it would but I’ve known the scale of the universe since i still threw myself birthday parties…lol
From that picture, it looks like you'd be on mercury and look up, see nothing but sun, But realistically it's 60% closer than earth
looks kinda like this from the surface
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
S---‐-------------------------------M--------------------------------------V----------------------------------E
Than
S---M‐---------------------------------------------------------------------V----------------------------------E
Yep, zoom and narrow aperture really messes with perspective.
It's kind of opposite of the tilt shift photos that make real life things look fake.
so is basically the whole sky sun on mercury during the day?
And this is why I worship the Sun
But pray to Joe Pesci, right? You pray to Joe Pesci, right?! RIGHT?
Praise the Sun! \0/
Bring forth the shears of stumping!
This reminds me of that part of that space opera I read where there was a nomadic colony on mercury which needed to always be moving at exactly the right speed to stay on the dark side of the terminator.
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.
The 3:2 resonance Klear references is considered a type of tidal locking.
Same here. I was so going to ackchyually that guy, but I did a quick check before and turns out there is a day/night cycle.
Apparently one Mercury day takes exactly two Mercury years due to some fuckery involving "3:2 spin-orbit resonance" which is something I'm too drunk to comprehend right now.
Gonna be an interesting wikipedia binge at work tomorrow tho
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.
The nomadic colony got expanded on in KSR's novel 2312. I don't actually remember much about it in the Mars Trilogy.
But I've seen the concept before in an old EU Star Wars novel, one of the Solo books maybe, where Lando was operating something similar as his new venture.
And before that maybe mentioned by Sagan. And before that...
I'll have to get 2312, haven't heard of that one. Same universe?
Adjacent, probably. Very similar, and seems to purposefully be set a hundred years after Blue Mars ends (2212).
Damn, that's a great idea. I gotta go back and finish that series.
Looks like a dead pixel.
The scale of the universe continues to blow my mind.
Prepare that mind for further blowage
This series is great. Thanks so much! I am getting sucked into a black hole of these videos.
Always happy to introduce a new person to Kurzgesagt
