@PM2Ring ahh, the OP's choice of words is the confusion source. As per James K, they mean orbit. I'll delete my comment and edit the Question.

Your claim that there is only one logical explanation has no useful evidence to support it, as we only have a sample size of 1 planet with life and none with significant amount of reactive gases. We have loads of theories, but all based on observation.

That definitely sounds like an image design question then. Getting an image onto a postage stamp is nothing to do with astronomy.

I’m voting to close this question because it is not an astronomy question, but a question about image printing or design tools

I’m voting to close this question because the OP just appears to disagree with published data for no apparent reason.

That absolutely looks like a digital filming defect. You see them all the time in pretty much any digital media.
