What would you send into an ocean if you had no idea who might find it? In 1977, Voyager 1 left Earth carrying something like a message in a bottle-not across water, but into the dark. It swept past Jupiter, then Saturn, sending home new views before continuing on a one-way journey. But Voyager 1 carried more than instruments. On board was the Golden Record: sounds, music, images, and greetings meant to introduce life on Earth. It was a hello for whoever might someday find it, not proof anyone has. In 2012, Voyager 1 crossed the heliopause, the edge of the Sun's protective bubble, and entered interstellar space. It had not left the solar system in every sense; it had crossed into the space between stars. Now, beyond our reach, it keeps moving. A greeting from Earth rides with it, still traveling beyond the Sun's bubble.
