A sketch of the spacecraft Voyager 1. 2017 marks the 40th anniversary of the spacecraft Voyager 1, which is currently some 20 billion kilometres from Earth travelling at 15.5km a second. It is the furthest spacecraft and man-made object from Earth and has left the solar system. It contains a gold plated audio visual disc with the sounds of earth, greetings of 'hello' in different languages and a music collection of world music in event the spacecraft is ever found by intelligent life. I wonder if anyone or anything will ever find it? I think it's pretty awesome it has taken photos from places we can only imagine and is teaching us so much about our universe. Sometimes you got to go outside of yourself to know who you truly are.
