Note: HD really helps.

The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecrafts, which were launched in 1977. They 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. The Voyager spacecrafts are not heading towards any particular star, but Voyager 1 will be within 1.6 light years of the star Gliese 445 in the Ophiuchus constellation in about 40,000 years.
