Come on flat-earthers. I know you are out there. Lets hear your crazy rant about how this is a fisheye lens on a weather balloon or a webcam atop the eiffel tower. Why can't we see the poles? And is that an ice wall on poking up in the lower-right quadrant of the disk?

My guess is the answer is: We didn’t really launch Artemis. This is all CG.

While the D5 is a great camera it's ~10 years old. Wonder why they didn't go for the Z9 which is its modern mirrorless equivalent.

They did bring the Z9: https://petapixel.com/2026/04/02/a-nikon-z9-made-it-aboard-t... But yeah the grainy photo of the Earth with the D5 at ISO 51200 shows the shortcomings of the ancient DSLR. Still, great shot.

I'd argue the D4s and D5 may be some of the best high ISO cameras I'm aware of maybe surpassed by that one canon video camera that can seemingly see in the dark (sorry I'm mobile) and the D3s. I think the lower numbers produce nicer looking max ISO noise but that's all preference. Sony has the A7s as well but as with some of these the overall resolution isn't extreme.

whats different between this and all the other pics of earth from various space devices

It’s taken by a human on the way to the moon.

That's enough for me. There was also much hype about a new blue marble picture, but I'm ok with that.

I was confused when I first saw this photo, as I don't think I've ever before seen a nightside, moonlit Earth, exposed so that it looks like the dayside at a first glance. I wonder how many casual viewers actually realize it's the night side. A nice demonstration of how moonlight is pretty much exactly like sunlight, just much much dimmer. In particular it has the same color, even though moonlight is often thought of…

> even though moonlight is often thought of as bluish and sunlight as yellowish! Is that... true? Sunlight is seen as yellow, of course, but the moon is usually thought of as white.

That's fair, I was thinking of how night, or twilight, as a whole is associated with cool hues, but it's probably true that moonlight in itself is usually thought of as neutral white.

No, it's BBC's compression of that image. Look at the original: https://www.nasa.gov/image-detail/fd02_for-pao/ It's grainy, but the detail is terrific.

@dang, mods: maybe this should be the post's link. The image quality is much higher.

Moonlight is reflected sunlight.

That's obvious. But the moon is so perfectly neutral gray that the reflected light is essentially the same color as the incident sunlight.

It really is crazy when you think about it, we're capable of taking a picture of the planet we live on from outer space. We take it for granted, that we know what it all looks like. I often find myself wondering how ancient peoples before us would react to something like this

Especially if they knew the sad state of the world whence the rocket was fired from, almost as a distraction of the decay of modern society mankind faces because of their fancy tech and the madmen it enables. I used to be fan of all space tech related stuff, but to me it has lost a lot of its shine. The people of old may say "hey, it is just like Easter island, except their monuments are dedicated to the God of Tech".

"It is the first time since 1972 that humans have travelled outside of the Earth's orbit." But they're not tho (Earth's gravitational dominance extends 4x the distance to the moon)

Theyre travelling to a region of space where the moons gravity is more important than the earths though. I think that counts
