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.
Frank Drake now fears it may have been a bad idea to send the maps into space. The article about Drake was actually written by his daughter Nadia, who asked whether it may one day be seen as “foolish and dangerous” to have broadcasted details of our whereabouts to aggressive aliens. Many scientists now believe contacting extraterrestrials is a spectacularly bad idea.
