The Sun and The Big Bang Theory

Today I watched the latest episode of The Big Bang Theory. During the opening sequence we fly from way out into the milky way and into our solar system pass our sun and ending at the earth. This time I got a déjà vu, and not just because I've seen the opening sequence many times before but because of some smaller visual stuff.

Here is a screenshot from the opening sequence of The Big Bang theory:

A few weeks ago I discovered a cool program called Celestia. With it you can fly around in space and look at planets, moons, stars and of course the sun. This can all be done at any time in history or the future. The textures on the planets are as close to "reality" as possible but the sun is basically just a big yellow ball with a few dark sunspots on it. This texture is used for all stars in Celestia so I doubt the sunspots are actually those of the sun but instead just random ones.

Here is a screenshot from Celestia of the Sun:

Did you notice anything? Here is a close-up of my déjà vu:

It might not be a secret to other people but at least now I know how they made parts of the opening sequence to The Big Bang Theory - or at least where they got inspiration.
