You'll likely catch this image a million times in your various feeds: Earth as seen by Reid Wiseman from Artemis II en-route to the Moon.
My first thought? That's *really* noisy 🧐
But then I realised – it's the *nightside* of Earth, illuminated by the almost full Moon, not the Sun 🌕
The bright limb at lower-right is where the dayside starts, & the fact that you can see aurorae, airglow, & cities in Europe, Africa, & S & N America also gives the game away.
Cool.
