Alien Moons, Slowly Explained for Sleep

Tonight, drift outward from Mars to Pluto and stop at the moons along the way - Phobos slowly falling, Io's lava lake, the ocean under Europa's ice, Titan's methane rain, Enceladus snowing into space, the tallest cliff in the solar system, and Pluto and Charon facing each other forever - narrated softly over calm music to help you fall asleep. Dim the lights, lower the volume, and let yourself drift.
