Yup… sure… that’s a real photo.

You can see clouds on the dark side of the earth, completely opposite the sun. They aren’t even trying.

And the phenomena of the earth being half lit and half dark would occur EVERY SINGLE SECOND OF EVERY SINGLE DAY. It’s nothing spectacular or unusual. The calendar plays no role in that. The sun is always going to light half the planet and keep half the planet dark. And if you really had satellites, you could position them to take that photo every single day.
