Someday...

Kepler-186f is the first Earth-size planet discovered in the potentially 'habitable zone' around another star, where liquid water could exist on the planet's surface. Its star is much cooler and redder than our Sun. If plant life does exist on a planet like Kepler-186f, its photosynthesis could have been influenced by the star's red-wavelength photons, making for a color palette that's very different than the greens on Earth. NASA's been searching high and low for extrasolar planets—the Kepler Space Telescope recently found it's 1,000th exoplanet. And in case you're having trouble deciding which one you'd like to visit first, the agency has put out a trio of posters, in the style of the U.S.'s old Works Progress Administration, advertising the wonders in store for travelers beyond our solar system.
