"Nasa's Voyager 1 spacecraft, is 24 billion kilometres from Earth, requiring a powerful network of dishes on Earth to be communicated with.
In April, Isaacson calculated whether some of these transmissions, up to 20 kilowatts, might reach other stars. He found four nearby stars and any accompanying planets would have already received the transmissions.
