3 Messages We've Sent to Extraterrestrials

In the 1970s, Frank Drake and Carl Sagan initiated projects to send messages into space, hoping to communicate with extraterrestrial life. They created plaques for the Pioneer 10 and 11 missions, which included scientific diagrams and a pulsar map. Later, the Voyager probes carried the Golden Records, featuring sounds and images from Earth. Additionally, the Arecibo message was sent via radio waves, encoded in binary. Despite the low chances of these messages being received, they represent humanity's attempt to reach out to the cosmos and reflect on our existence.
