Found these clouds at work today. (I look at space images all day long 
) It really reminds me of a perlin cloud texture 
cool, you work for nasa?!
That’s real!? You’re right, it does look very procedural.
It awesome - i can almost make similar in blender.
I guess you can’t call the use of Perlin cloud textures in space images made in Blender crappy anymore.
Ok I couldn’t resist trying to duplicate it. I used a couple Voronoi F1-F2 textures. guess which one is real

Your texture needs more intensity and less transparency, I can easily tell the difference.
Yes. That’s why the procedurals are the way they are. Because they’re realistic and easy to duplicate mathematically.
Could you please tell me where you work so I can submit a job application? Thanks.
No, this is more like it:
Made in Blender 2.44.
>XD
Yeah, sometimes you’d think it’s actually the other way round…while in general, procedural textures imitate nature.
But nice find anyway…it really looks artificial…or, do the textures actually look natural? Confusing 
Tynach: wow thats almost perfect! What are your settings for that texture?
And I don’t work for NASA, but I wish I did. I’m working on a couple of picture books of the solar system. I’m constantly amazed at the amount of publicly available images on the internet, here are a few links:

I know this is years later (11) but would still know how this was done. If anyone know, please post a node setup
Thanks
Well, math itself is a way of expressing the logic of the universe, so it fits

You’ll never look up at the sky in quite the same way again . . .
