Those of you into collectible travel items and/or space travel will probably enjoy these stunning posters NASA’s Jet Propulsion Laboratory created in honor of a few of the exoplanets they’ve discovered with the Kepler space telescope.
An exoplanet, of course, is a planet orbiting a star other than our own.
