Thanks to the twin Voyager spacecraft, music is truly universal: Each carries a Golden Record with sights, sounds and songs from Earth as it sails on through the Milky Way. Recalling the classic rock era of the late 1970s when the Voyagers launched, this poster is an homage to the mission’s greatest hits. Some of the most extraordinary discoveries of the probes’ first 40 years include the volcanoes on Jupiter’s moon Io, the hazy nitrogen atmosphere of Saturn’s moon Titan and the cold geysers on Neptune’s moon Triton. Voyager 1 is also the first spacecraft to deliver a portrait of our planets from beyond Neptune, depicting Earth as a ‘pale blue dot,’ as of Aug. 25, 2012, to enter interstellar space. Voyager 2 is expected to enter interstellar space in the coming years. Even after 40 years, the Voyagers’ hits just keep on coming.
