Not arguing that PNG is the right choice, but you want something lossless for science purposes, and this is a science image.

You can tell roughly what order the impact craters were formed by seeing what overlaps what; looks like the small impacts mostly followed the big impacts. Maybe the earth's orbit cleared out the bigger stuff first? If you had a really good image, you might be able to work out the average impact angle, and therefore the average speed of impact, since we know the speed of the moon, and how they would intersect. Nothing's filled with lava like it has on the near side of the moon, which makes me think these have mostly happened later in the moon's life, when it's cooled down a bit.

I just love space, I've no education in it. I bet someone with a fancy moon science degree would be able to tell you a lot more, and they'd be poring over every pixel. Don't want any JPEGs getting in the way of that.

Why's that?

Oh guess the AI folks haven't yet realized that you can increase perceived accuracy by adding a small amount of random noise.

Which of course they didn't, because then they'd need to understand some things about images instead of just throwing whatever data they can find at it and hoping it figures it all out from that.

Though I'm not sure how much it applies to images, as the examples I've seen were audio. But it's cool to hear a low bitrate audio sample of someone talking unintelligibly and then play that same clip with random noise also playing and suddenly you can understand what is being said.

The diffusion models at least were basically designed to "remove noise from a random image until a real image emerged" so that actually makes a lot of sense, interesting

Lemmy probably returns images in different formats depending on what client supports (and ones with better compression take precedence).
