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.

@markmccaughrean how much of the ”noise” is satelites?
@whangdoodler None in that picture – the Sun is hidden behind Earth, so there’s nothing bright to light them. Moonlight is far too faint to lead to significant illumination. But the satellites are still there, mostly you know who’s endless cheap wifi routers 😬
@whangdoodler @markmccaughrean none, that’s just shot noise.
