It Still Reaches Earth From 15 Billion Miles Away 19FortyFive Voyager 1 is still transmitting from more than 25 billion kilometres away, powered by less than 250 watts of decaying plutonium — a signal that now takes over 23 hours to reach Earth, carried by a radio no stronger than a refrigerator lightbulb Make Tech Easier The engineers who built Voyager knew they would almost certainly be dead before it left the solar system, and they built it anyway, a gift from people who would never see where their work would go ScienceBlog.
