The Voyager Golden Record.

READ MORE: https://voyager.jpl.nasa.gov/

The Voyager Golden Records are two phonograph records that were included aboard both Voyager spacecraft launched in 1977. The records contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. Those records are considered as a sort of a time capsule.

Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space, but the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet."

Voyager 1 was launched in 1977, passed the orbit of Pluto in 1990, and left the solar system (in the sense of passing the termination shock) in November 2004. It is now in the Kuiper Belt. In about 40,000 years, it and Voyager 2 will each come to within about 1.8 light-years of two separate stars: Voyager 1 will have approached star Gliese 445, located in the constellation Camelopardalis; and Voyager 2 will have approached star Ross 248, located in the constellation of Andromeda.

In March 2012, Voyager 1 was over 17.9 billion km from the Sun and traveling at a speed of 3.6 AU per year (approximately 61,000 km/h (38,000 mph), while Voyager 2 was over 14.7 billion km away and moving at about 3.3 AU per year (approximately 56,000 km/h (35,000 mph).

Voyager 1 has entered the heliosheath, the region beyond the termination shock. The termination shock is where the solar wind, a thin stream of electrically charged gas blowing continuously outward from the Sun, is slowed by pressure from gas between the stars. At the termination shock, the solar wind slows abruptly from its average speed of 300–700 km/s (670,000–1,570,000 mph) and becomes denser and hotter.

Of the eleven instruments carried on Voyager 1, five of them are still operational and continue to send back data today. It is expected that there will be insufficient energy to power any of the instruments beyond 2025.

On September 12, 2013, NASA announced that Voyager 1 had left the heliosheath and entered interstellar space, although it still remains within the Sun's gravitational sphere of influence.

This space probe will eventually become the only interstellar evidence of our existence. Knowing that this space probe will outlive all humans to ever exist... it's beautiful and horrifying at the same time.
