A star-less planet, wandering the galaxy in the dark
Finally, we have PSO J318.5-22. (Not the easiest name to remember, but maybe someday the Exoplanet Travel Bureau will rebrand it.) It’s an extrasolar object about 80 light-years away that doesn’t appear to have a host star, so it wanders the galaxy alone as a free-floating (or rogue) planet.
Not having a star, it would always be night on this planet, which is what the poster makes reference to with the line: “where the nightlife never ends!”
All these posters were created for NASA’s JPL by brothers Don and Ryan Clark at Invisible Creature, a multi-disciplinary design and illustration studio based in Seattle. Coincidentally, the Clark brothers' grandfather was Al Paulsen, an illustrator and graphic designer at NASA for more than 30 years at the Ames Research Center in the 1960s.
It’s clear that posters from the past still inspire us. If you want to see a deliciously strange vision of the future, look at these posters from 1900 France depicting what people at the time expected the year 2000 would be like.
