There’s a comic book series from the 1970s called Altri Mondi (“Other Worlds”) by Italian physicist and illustrator Andrea Romoli, that only ever came out in Italian and Spanish. Despite this, it was adapted in the 1980s into a 77 episode TV anime called Spaceship Sagittarius. Most of it are original stories not directly based on the comic books, though.

By the way, watch it if you get the opportunity, it’s good.
