Abstract:  In a communication technique using the apparent distribution of stars and other celestial bodies visible from the earth to generate codes corresponding to communication characters such as the English alphabet and or Arabic numbers, the characters of a conventional keyboard, or any other suitable character set. The stars, or subset of stars, or combinations of stars and other celestial bodies to be used may be divided into sections; the stars or stars and celestial bodies of each section may be assigned to represent one or more characters of the character set to be used. A communication to be sent is prepared by replacing each conventional character of the communication with the section of stars that correspond to the character. The resulting communication is unrecognizable as a conventional communication, it has a high degree of security, and yet it has an esthetic or romantic appeal similar to that of the night sky. Any celestial communication may be decoded by reversing the procedure.
