.On November 16, 1974, people sent their first notification to the celebrities in an attempt to speak to extraterrestrials. They performed this using what was at that point the most extensive radio telescope around the world, found at the Arecibo Observatory in Puerto Rico. A team of experts led by Frank Drake and also Carl Sagan delivered their message to the M13 star cluster.
