Astronomy articles celebrate Voyager spacecraft leaving the solar system

Recent science journal articles celebrate the achievements of the Voyager spacecraft. In 1977, NASA launched two Voyager spacecrafts, 1 and 2, each the size of a small car, to visit Jupiter, Saturn, Uranus, Neptune and their moons. Then the craft were programmed to head straight out beyond the reaches of the Sol star. Originally built for a five-year mission, the Voyager craft have been sending signals back to Earth for the past 36 years. Attached to the spacefarers are gold-plated copper phonograph records that contain pictures, languages and sounds about Earth and human culture.
