Galaxies on Instagram: "When NASA launched the Voyager 1 spacecraft in 1977, they included along with a golden record, meant to be the first impression of humanity. On this record included a series of over 100 pictures meant to depict human life on earth and the human race in general. Voyager 1 has reached almost one light day away from Earth, but still hasn’t encountered any other forms of life. How do you think aliens would interpret these images?"
