A common concern with new satellite constellations like Starlink is that the fact that they rely on large numbers, they make ground-based astronomy more difficult by adding more noise and possibly obscuring targets.
This comic satirizes that by talking about a hypothetical satellite company that launches *deliberately* inaccurate starmaps to be overlaid across the night sky.

[White Hat and Ponytail are standing on the left, Cueball is on the right, in front of a poster on the wall. The poster has a portion of the Earth at the bottom, with outer space above it. The space scene has lots of stars, along with a few nebulae and galaxies. Part of the space scene is enclosed in a quadrilateral (a slightly skewed rectangle).]
- Ponytail: Aren't you worried these will be disruptive for ground-based astronomy?
- Cueball: No, why?
[Caption below comic:]
- My new company is being criticized for our satellites that deploy 100-mile-wide banners painted with inaccurate pictures of the night sky.

- If the question is how it can be written like that here, the answer is that I used the numbers of the wiki. βWhile False (speak|museum) 19:18, 4 October 2022 (UTC)
- Sorry, should have made it more clear. Do you know why it is shown as 0 bytes on the file page? 172.70.134.103 12:37, 7 October 2022 (UTC)Bumpf
- There's always the possibility that this is actually the Null image under the .png file format. Every other .png is defined by the delta required to display the desired graphic when starting from the baseline of this 'ur'-image, but if you ever wanted to display that graphic the undocumented format specifications allow you to omit all unnecessary bytes (including the magic header bytes) and it will happily produce its hardcoded "it's a PNG!" preprocessing template, which happens to be this image. Obviously, the PNG spec (and, ultimately, the original ancestor of the detailed source code tree for every subsequent implementation) was written before Randall ever got anywhere near to drawing this image so the chances are slim that he just happened to luck upon the exact image that happens to have a 100% compression rate because it just happened to consist of something Randall wanted to draw, and in the manner of Randall's artistry. But it's a non-zero likelihood that an arbitrary artist might draw exactly the same image as a purely arbitrary "index null" page's collection of pixels and so... This might not be the Best Of All Worlds, but there has to be some highly fortunate occurance to balance out all the unfortunate ones, statistically, and this is ours!
- (Or maybe there's a minor bug/data-error in the way the wiki database serves the front-end webserver, but I can't ask you to believe something as trivially random as that!)) 172.70.90.245 15:03, 7 October 2022 (UTC)
