Back in the optimistic early days of space exploration, everyone thought it was a great idea to offer aliens a chart telling them how to find Planet Earth. But now the man who sent four maps into deep space fears this decision could prove to be disastrous. Frank Drake, an American astronomer and famed alien hunter, worked with NASA to design maps which were placed inside Pioneer 10 and 11 as well as Voyager 1 and Voyager 2 probes. All four of these spaceships have now left the solar system and are speeding through deep space. The plaque placed aboard the Pioneer craft shows a man and a woman alongside a basic map which plots the position of Earth compared to a distant pulsar stars, which are bright and long-lasting so could still direct aliens our way if they are found millions of years from now. Voyager was fitted with “golden records”, which can be played to reveal natural sounds and even images from Earth. A similar pulsar map is engraved on the front of the records. Frank Drake now fears it may have been a bad idea to send the maps into space.
