By now, you have seen the Earth image by the #Artemis crew at least a hundred times. In this annotated version, several #optics effects are highlighted. It also shows how fragile planet #Earth is, with a super thin #atmosphere protecting us from the harsh vacuum of space.
Let's protect it.

If this is the night side of Earth, lit only by moonlight and presumably photographed in long exposure, shouldn't the city lights be much brighter than this?

Or are city lights a lot less visible from orbit than I've been led to believe? 😵‍💫

@argv_minus_one @pfsmet

This other picture posted elsewhere in the thread shows what it looks like at an exposure closer to human vision. If you zoom in you will see city lights too. But I think the areas that are visible (Spain and Portugal near Africa, and Brazil on the other side) are not the most illuminated cities on Earth...
