Something we built in 1977 is now in interstellar space.
Something we built in 1977 is now in interstellar space — farther from Earth than you can properly picture. Voyager 1 sits over 24 billion kilometres away, well past the heliopause, the outermost edge of the Sun's influence, which it crossed in 2012. When it sends a signal home, that transmission travels at the speed of light and still takes over 22 hours to arrive. We are receiving a whisper from beyond our solar system. It runs on a nuclear battery, quietly ticking, and it carries the Golden Record — sounds and images of Earth, placed there for whatever, or whoever, might one day find it. Forty-seven years on, the furthest thing humanity has ever made is still reaching back towards us. Follow Deep Field Vault for more of the universe, one true fact at a time.
