Teen Age Message

The Teen Age Message (TAM) was a METI message, transmitted from the Yevpatoria Planetary Radar to 6 nearby Sun-like stars during August–September 2001. Unlike the previous digital-only Messages, Arecibo-1974 and Cosmic Call 1, the TAM has complex, three-section structure with different forms of information. Such structure was suggested by Alexander L. Zaitsev.^[1]

• Section 1 represents coherent sounding radio signal with slow Doppler wavelength tuning to imitate transmission from Sun's center. This signal was transmitted in order to help extraterrestrials detect the TAM and diagnose the radio propagation effect of interstellar medium.
• Section 2 is analog information and represents musical melodies, performed on the Theremin. This electric musical instrument produces quasi-monochromatic signal, which is easily detectable across interstellar distances. There were seven musical compositions in the 1st Theremin Concert for Aliens.
• Section 3 represents a well-known Arecibo-like binary digital information: Logotype of TAM, bilingual Russian and English Greeting to Aliens and Image Glossary. This section and the Concert program were composed by teens from different sites of Russia.

The project is so named because of the age of most of the participants.

Stars to which the message was sent are the following:^[2]
