I object to being included in this image without a model release and demand that pixel be removed.

Tell the world you're REALLY fat without telling the world ...

"Your mom is so fat she would take a whole pixel on that image"?

I love the fact that you can see the aurora at both poles!

I wish I could see a pic from today with the aurora. I was surprised to see the aurora in northern Europe a couple hours ago, it is very active right now.

Yeah, it is - unfortunately, it is rather cloudy in my area at the moment. Luckily, the weather was better during the 19./20. January event, which I'll carry forever in my heart.

Looking at the EXIF (with exiftool) for the image uploaded by NASA ( https://www.nasa.gov/wp-content/uploads/2026/04/art002e00019... ), apparently this was taken by a Nikon D5 with an AF-S Zoom-Nikkor 14-24mm f/2.8G ED and developed with Lightroom. It also seems like very little was done in Lightroom. Amazing... I dumped the whole EXIF here: https://gist.github.com/umgefahren/a6f555e6588a98adb74eed79d...

250 ms f/4 ISO 512000 in case anyone was wondering. I wonder if they applied any denoise, it looks great for such high ISO

Earlier quoted context omitted.

Before Lightroom it might have looked closer to this: https://images-assets.nasa.gov/image/art002e000193/art002e00...

The photograph appears to show nightime on Earth with just a sliver of daytime. Beyond cities in Iberia and along the coast of Africa, most of what we can see would be reflected light from the Moon? We are just past full moon on April 1.

1/4 exposure time so 250 ms of light. the light is coming from all the light sources in the universe, plus the moon, plus the sun's rays refracting through the atmosphere which happens even at night.

The natural blue light is coming from the oxygen in the atmosphere but it's so overwhelming in that spot that it turns the light pure white. The red/orangish is coming from particulates and the green/red from aurora. My favorite part I think is the very bottom where you can see the blue light taper off and not overwhelm the camera sensor and you can see the aurora with it. I love this photo so much.

Probably my favorite photo ever now.

Much higher quality images are available on the NASA Image Library: Dark Side of the Earth: https://www.nasa.gov/image-detail/amf-art002e000193/ Hello World: https://www.nasa.gov/image-detail/fd02_for-pao/ On images-assets.nasa.gov, we can find the 5567x3712 resolution versions of these pictures: Dark Side of the Earth: https://images-assets.nasa.gov/image/art002e000193/art002e00... Hello World: https://images-assets…

It disappoints me greatly they're not raw :(

... My only curiosity, and yeah I know orders of significance etc... Buuuuut I wonder why they didn't consider a Z5[0][1] and the Z mount 14-24, or the Z5 with an adapter for the F mount 14-24.... There's at least a pound of weight savings on the table. Specifically, I wonder if it's a fun reason? i.e. it would be interesting if there was a technical reason like 'IBIS fails miserbly' or 'increased sensor resolution a…

They have a Z9 on board for radiation testing, but the D5 is the primary body for imaging on this mission IIRC

That's what the caption the article above says

Ridicule them until they leave? Don't really feel like wasting my time on any more than that.

Exactly what Professor Dave does.
