Voyager 2 is a spacecraft used by NASA to explore Jupiter, Saturn, Uranus, and Neptune. It is the only spacecraft that has come near to Uranus and Neptune. Because of this, a majority of pictures we see of these two ice planets came from this spacecraft. It was identical in form to its sister ship, Voyager 1. The probe is currently moving away from the solar system, and is heading out into interstellar space.
Voyager 2 was launched on August 20, 1977.
Both Voyager 1 and Voyager 2 include the Voyager Golden Record, which is a recording of sounds and images of life on Earth. It was designed by a team headed by Carl Sagan to communicate with extraterrestrial life.
In 2018, NASA announced that Voyager 2 had reached the heliopause on 5 November of that year.

The current position of Voyager 2 as of December 2018. Note the vast distances condensed into an exponential scale: Earth is one astronomical unit (AU) from the Sun; Saturn is at 10 AU, and the heliopause is at around 120 AU. Neptune is 30.1 AU from the Sun; thus the edge of interstellar space is around four times as far from the Sun as the last planet.
