Is this a real picture? Or Manmade/computer generated?

Hi. I bumped into a nice picture.

Is that a real picture? Was it computer generated? Artificial? I've heard of World Wind, program to do stuff similar.
Can someone please tell me the source of that picture?

Thank you for your time.

Absolutely artist's rendition. Unfortunately, we as yet do not have cameras on exoplanets
