content: Usually with picture subredd subverses, my test is whether the image stands alone without the title. In this case it doesn't. I'm not going to say this doesn't belong here (because you seem like a nice guy), but the news that there's a new image coming would probably better belong in a science subverse with an article. Someone that isn't familiar with New Horizons and sees this has no idea what you're talking about. Just my opinion.
