A 47-year-old spacecraft is still talking to us.
Launched in 1977, Voyager 1 has been falling through space ever since — and it has never stopped transmitting. Right now it sits over 24 billion kilometres away, deep in interstellar space, beyond the Sun's own bubble of influence, which it crossed in 2012. When it sends a signal home, that radio whisper travels at the speed of light and still takes over 22 hours to arrive. Think about that. Light speed. Twenty-two hours. The probe runs on a nuclear battery, slowly fading but not gone yet. Tucked inside it is the Golden Record — sounds and images of Earth, addressed to whoever might one day find it drifting through the dark. We built something, threw it outwards, and it is still reaching back towards us. Follow Deep Field Vault for more of the universe.
