Why, in heaven's name, does NASA's official "photo" of the globe Earth change over the years as CGI technology changes?
Shouldn't there be more consistency, if it's a real picture taken from space?
Asking for a friend.

Also, I heard in *many* science videos about planets, space, the Earth, the Moon, etc. that the Earth bulges at the equator due to centrifugal forces associating with spinning so fast.
Why isn't this reflected in the "real photos"? Is it too much trouble to have the artists add this feature to their CGI?
I watched lots of videos like "What if the earth stopped spinning" and so forth. It's considered common knowledge that the earth is larger at the equator, the earth itself bulges out a bit due to centrifugal force, like kids being pulled outward on one of those whirlygig/merry-go-round things we used to have in parks in the 1980's.
But look at the photos -- those are perfect spheres if ever I saw one. Not the slightest bulge anywhere.
