The space agency's "Exoplanet Travel Bureau" website allows users to virtually tour six alien worlds. Think of it as an intergalactic vacation with interactive experiences. The website shows 360-degree images of the planets, which are outside of our solar system.
The Bureau also offers posters of all six planets. Most of the destinations featured on the site were found by NASA's Kepler Space Telescope. The telescope has discovered over 23-hundred exoplanets since 2009, but no actual images of them exists. An artist brought them to life.
