NASA’s Jet Propulsion Laboratory designed a series of travel posters and made them into 2016 calendars as a gift to NASA and JPL employees, partners, and friends. There are familiar planets, exoplanets, and moons, plus a couple of tour posters.
Now we all can have these gorgeous creations. All 14 of them are at the JPL site, where you can download them poster-size in case you want to are able to print them out. -via Metafilter
