Did you know we sent a message to aliens?

In nineteen seventy-four, humans sent a special message into space! This message was called the Arecibo Message. It was sent from a giant radio telescope in Puerto Rico. The message has a lot of information about us. It shows our numbers, our DNA, and even a picture of our solar system! They sent it toward a cluster of stars called M thirteen. This message is like a hello to aliens. Scientists hope it shows that we are here. But, it will take thousands of years for anyone to receive it. What do you think aliens would say back?
