The universe is constantly expanding, as is the wealth of fictional entities we imagine to occupy that space. iam8bit took the time to collect a good chunk of these space-dwelling planets, characters, and vehicles—and put them on a poster. The poster, which is beautifully illustrated by Edison Yan, features over 70 planets and over 50 vessels and characters. The objects come from movies, television shows, books, comics, and more, but you'll have to figure out what's from where on your own.
