In the late summer of 1977, NASA launched a pair of
interstellar probes, Voyager 1 and 2. Like most spacecrafts, these two were
built to gather information about unknown realms. More unusually, they also had
something to give in return: Each held a copy of what’s known as the Golden
Record, a set of images and sounds carefully chosen to give anyone who might
find them a taste of Earthly life.
