If you were curating a mixtape that might be heard by aliens billions of years from now, but definitely would be seen by your fellow Earthlings, what would you put on it? 

In 1977, two Voyager spacecraft launched from Cape Canaveral on a journey that would take them out to our outer solar system and beyond. Affixed to the side of these two planetary explorers was the Voyager Golden Record. This ultimate mixtape of humanity contained 27 pieces of music and also pictures, greetings in many languages, and the sounds of Earth. Nearly 50 years later, we're exploring what's on the record, how it got made, and its legacy with one of it's makers. Oh! and we brought in our friends from Sidedoor to help :)
