Is there a higher resolution image of this available anywhere? The 7000 x 1150 one is nice, but I couldn't find a link to anything larger. It says the original is 120,000 x 18,000 so it was a little disappointing to have the available version not even fill the vertical resolution of my monitor.
Yeah I'd pay for a full resolution version so I can get this printed across my entire wall. Despite the "high" resolution of many of the pictures on the page, not a single one is high enough resolution to print much larger than A3 or so while still seeing the stars/details.
Author is a professional photographer. Suspect that, with an email and a pile of cash, they’d license you the work.
I also was hoping to find a higher resolution image I could buy to print out somehow. The full resolution is 18k x 120k pixels. At 300 DPI that works out to be 60 x 400 inches. Or 5 feet tall and 33 feet and 3 inches long, or close to 2 meters high and 10 meters long.

I think I might have a hallway that it could fit in, but wow that’s big!

He's selling (up to A2 or so) prints via https://astroanarchy.zenfolio.com/ . Maybe you can contact him & ask for something larger.
I would absolutely buy something larger.
The largest option in his shop is actually 5m x 75cm, divided into 5 panels. But that also comes at a price of 7.5k EUR, or 12.5k EUR for a glicee print.
It could be the creator of the image is with holding that image from just tossing to the hordes in the hopes of doing something with it to possibly be rewarded for their effort.

Milky Way, 12 years, 1250 hours of exposures and 125 x 22 degrees of sky - https://news.ycombinator.com/item?id=26490579 - March 2021 (139 comments)

Wow!!! I’d like to read more details about the PC and software he used. Besides the Photoshop that is mentioned, no other details about the system (cpu, ram, disk…).
A professional large photo plot of this would probably look seriously impressive.
Even at 200 dpi this would be 15 meters wide and 2.25 meters tall.

Imagine that in a museum, just a massive wall with 100 billion stars. It would be ridiculously cool.

Realistically, that seems pretty achievable goal for a Kickstarter? Rent some smallish exhibit space (500-1000sqft old warehouse or something?) in the valley/bay area outskirts for a few months, find a large format printer service, print out in strips, and figure out physical installation. How much can that really cost? $10-20k total? Somehow I feel its not far fetched that there would be a thousand geeks willing to chip in $10-$20 bucks for this sort of thing
Might be even less.

Japan is huge on making very large graphics from printing on sheets of white adhesive: https://youtu.be/ioyMec7YU0Y

If they added it to the ground it cheaper to install and then kids could run on it in the gym (could easily cover an entire Gym, lol): https://youtu.be/mBjSM783Tug

Would be fun with the retroreflectors added like in the latter video, as with the lights off and only head lamps on you could see stars below your feet.

That's pretty neat. But I wonder what the surface looks like after removal?
Of the sticker? Very clean, because the adhesive is built to stick together like a command strip.
This is stunning work. Bravo! I feel so small and insignificant right now. And that's not a bad thing.
That's one of my favorite aspects of astronomy. To the universe, we're (Earth) just a spec on a dot. The stepping away from all of the things that seem so stressingly important and realize that it's only us that feels that stress and the universe really absolutely doesn't give a shit. It always helps me to give less of a shit too.
So true. If I happen to be do something new, high risk or making me stress out thinking about it in context of the larger universe (and staring at these pictures help) quickly puts me at ease. Very effective. I have passed this to others over the years.
I always look at the "Pale Blue Dot" image shot by Voyager if I ever have a need to feel insignificant. Never fails me!
Complete with Carl Sagan's magestic description:

You ought to see it in person, in any dark sky place - that would clear your perspectives
Apparently 100 billion stars in there. That is nuts.
Yup. Even at 1 in every 1 million systems, that could be 100,000 systems with life.

Or, even at 1 in every 10 million, that could be 10,000 systems with life.

In a way I hate these photos. It's like showing a kid an ultra delicious looking candy, but telling them that they will not be able to taste it in their lifetime.

But for all we know the odds could be 1 in every 100 billion; we have no way of knowing, almost any guess you'd make is equally unfounded.
It's like the one tank variant of the German tank problem[0], except the tanks aren't even numbered.

The scary (sad) thing to me is that it could be 1 of 1.
What are the odds we are the only one?
Nobody can tell you without pulling numbers out of thin air. That's the point. The only thing that can be said is that the probability of intelligent life arising is greater than 0, which follows from our own existence. Beyond that, any claims about the likelihood of intelligent life are just 20th and 21st century versions of "there must be a God because the universe couldn't have arisen by chance."
Strictly speaking our own existence doesn't even tell us the probability is greater than zero. For an event to have probability zero doesn't imply it can't occur. If a number is chosen from a uniform distribution on the reals between zero and one, whatever the result is the probability of that exact result occurring was zero.
The universe became conscious in the form of man and asked ‘who made me’ so it’s the universe arguing with the universe about a creator :)
the candy might also be filled with razors and end all life on our planet though
Oh crap, now not only do I have to live in disappointment that I won't get to eat the candy, I also have to live in fear that the candy monster might come by and eat me.

Sad and Scared... my life is over...

well, guess we should spend our whole lives praying just in case
oh man, has the news been running halloween stories in your area again?
Damn, I wish my engineering journal had drawings like that in it.
Question: What would it look like to be living on an electron, whizzing around a proton, inside a molecule, inside a living being?
Depends on what _you_ are made of. If you're small enough to live on what is a point particle in our universe, then your concept of "looks like" will be different than ours. For one thing, your interaction with photons will be different than ours.
Intense pareidolia a quarter of the way across, of a sci-fi warrior/genie dude holding up a weapon.
Question: why are pictures taken from the space station showing really dark space ? The pictures of the mosaic have many stars and I guess the milkyway can be observed from earth too. So why all that black on the photos taken from space ? An issue with contrast ?
IANAAstrophotographer, but I'd say it's indeed a contrast issue (dynamic range of cameras). Most ISS photos are taken on the day side and have Earth in view; the brightness of reflected light is so great it prevents cameras from recording stars. A quick googling for photos taken from ISS at night reveals that they do feature stars in them.
"Exposure time over 1500 hours between 2009 - 2021"
I would love to see this edited into some viewscreen images on the NCC-1701[-D] bridge.
Damn! So much out there that we might never be able to see.
Where is the Earth in this?
