What an amazing view of Earth from Artemis II.

The Sun is behind the Earth, illuminating a thin crescent. This low-light shot, taken by Reid Wiseman using a Nikon D5, shows auroras over the poles, city lights, and the glow of the atmosphere.

And yes, there are stars!

To be clear: We're basically looking at an eclipse of the Sun, by the Earth.

This is the night side of our planet, illuminated by the light of the full Moon, seen in a long exposure. Wow!

Show threadCorey S PowellApr 3

Here is another version of the marvelous new Artemis II view of Earth, taken just minutes later.

This shot uses a shorter exposure, emphasizing the night side of our planet as it eclipses the Sun.

@coreyspowell I felt that they should have mentioned the light source in the text - it's an omission that almost seems intended to provoke commentary.

@coreyspowell
Thanks for the clarification!

I’ve been to Sahara when the landscape around me was lit up by just stars and the full moon, but I never thought about the fact that all Northern Africa and much of the rest of the planet also was lit up.

Yet another obvious thing I did not think of…

They won't ever care about any proof. If some proof could convince them, it would have already, there are tons of them.

Anything that contradicts their model is simply labeled as "fake". AI will probably make it worse.

@ZenHeathen @vk6flab Thank you! I hadn't seen the CSA one, I'll set that one up on my wall display. The fan-made one seems to have the wrong data (it's significantly ahead of where the mission actually is in both MET and distance) at least on my machines.

@sen I notice that sometimes the CSA one seems behind, to me, though not by a lot. More data is better! Think of how worlds ahead we are compared to folks at home wanting news about Apollo! @vk6flab

@coreyspowell Thanks for posting this photo and sharing the link! ❤️

Is there some reason why this image has been rotated? The one on the website is oriented differently (see attached image).

The description from NASA website seems to match up with this image, especially the fairly bright "zodiacal light" - a term which I learned today!

@coreyspowell Notice the aurora glow at 1 and 7 O'clock. That level is still far above our usable atmosphere. It is easy to see how that thin layer can easily be filled with human generated green house gas and pollution. Its like we are the fish swimming in our own tank of waste, hoping the filter system does not break down. :)
Show threadOutfrostApr 3

@coreyspowell Not that long of an exposure, as far as astrophotography goes anyway - just 1/4 s. The amount of light captured is thanks to the wide open aperture (f/4), which also made details blurry, and the insanely high sensitivity setting (ISO 51200), which put a ton of noise over the whole image, and made a lot of stars indistinguishable from aberrant pixels :(

as a photography nerd this makes me a little bit sad, especially since the settings were manual

@coreyspowell I like how if we zoom in, it gets really clear that when we see a thin bright line half around the globe in those videos, it's limited to the atmosphere. I had never understood why that happened, until now.
