I made a bookmark based on the Arecibo Message. It's a constant radio transmission from earth to space. It offers information to potential alien visitors.

Dr. Frank Drake, then at Cornell University and creator of the famous Drake equation, wrote the message, with help from Carl Sagan, among others. The message consists of seven parts that encode the following:
* The numbers one (1) through ten (10)
* The atomic numbers of the elements hydrogen, carbon, nitrogen, oxygen, and phosphorus, which make up deoxyribonucleic acid (DNA)
* The formulas for the sugars and bases in the nucleotides of DNA
* The number of nucleotides in DNA, and a graphic of the double helix structure of DNA
* A graphic figure of a human, the dimension (physical height) of an average man, and the human population of Earth
* A graphic of the Solar System
* A graphic of the Arecibo radio telescope and the dimension (the physical diameter) of the transmitting antenna dish
