The twin Voyager spacecraft, the first of which began its journey on August 20, 1977, carry the sights and sounds of Earth on gold-plated records.

The two probes explored the worlds of the outer solar system, and continue to return to data as they reach the boundary between the Sun's sphere of influence and interstellar space. [NASA/JPL]
