Advanced alien civilizations could find our planet with the aid of Cosmic Maps NASA launched into space some 40 years ago. However, Dr. Frank Drake, the man who helped design the charts has suggested these maps could be dangerous for our species. 

Our quest for alien life goes back more than you’d imagine. But perhaps the most important step towards finding our cosmic neighbors began in the 1970’s when NASA sent maps revealing our planet’s location into space, onboard of four spacecraft in hopes that one day we would be able to communicate if anyone else is out there.

However, despite the fact that sending the maps of Earth into space was a great step for mankind, the creator of the maps—Dr. Frank Drake—has spoken out about the potentially ‘dangerous’ decisions to send the maps into space over 40 years ago.

All f the four spacecraft carrying the maps—Pioneer 10, Pioneer 11, Voyager 1, and Voyager 2—have left our solar system and are heading towards deep space with our planet’s coordinates embedded onto their body.

Dr. Drake who worked at NASA to design the ‘cosmic’ charts placed on board Pioneer 10 and Pioneer 11 launched in 1972 and 1973 respectively believes not everything is positive about sending the maps.

In an interview with his daughter Nadia Drake, a reporter from National Geographic, Dr. Drake said: “In those days, all the people I worked with were optimists, and they believed how ETs would be friendly, Nobody thought, even for a few seconds, about whether this might be a dangerous thing to do.”

The plaques placed on board the Pioneer spacecraft are a message from our civilization. They depict a man and a woman standing side by side, next to a map of Earth, which plots its position in relation to distant pulsar stars.

Why pulsar stars? Because these stars are long-lasting stars and are so bright that they could help guide aliens in the right direction towards Earth.

The maps on board the Voyager spacecraft are of similar design. The Voyager 1 and 2 feature a golden record on board, with similar pulsar stars to our planet.

NASA wanted to put something on board the spacecraft saying where we come from, who we are, and how long our spacecraft were traveling.

Furthermore, the records also contain various sounds from nature, and noises produced by humans like a train, and a kiss between a mother and a child.

However, despite all potential danger these cosmic charts pose in outer space, Dr. Drake says that the chance of Aliens intercepting the messages and finding out wehre we are are “very small”

“The thing is going something like 10 kilometers [6.2 miles] per second, at which speed it takes – for the typical separation of stars – about half a million years to go from one star to another,” added Dr. Drake.

Apparently, things about E.T. and visitations to Earth changed since the 1970’s. Now it seems more people are inclined to avoiding aliens at any cost.

Now, more experts are leaning towards the idea that we should not reveal ourselves to aliens.

Professor Stephe Hawking said in an interview that if aliens found us, it would be something comparable to when the Native Americans first encountered Christopher Columbus—something that did not turn out so well for the natives.

Stephen Hawking has said that if aliens ever discovered Earth, they would probably want to conquer and colonize it.
