Astronomers sent a message to the exoplanet 12 light-years away from us, which, among other information, also contains 18 excerpts of electronic compositions, including techno, says The Mercury Times.
Researchers have been sending messages into space for decades in the hope of finding traces of intelligent extraterrestrial life. One of the most famous messages is the Voyager golden records, which contain greetings in 55 languages, music and various sounds, as well as photographs of our planet and its inhabitants. In addition, scientists have repeatedly sent radio signals to nearby stars, where they believe other civilizations could potentially exist.
METI collaborated with Sonar, Spain's electronic music festival, to send a signal to GJ 273, also known as Leiten's star. Its mass does not exceed a third of the Sun's, and its diameter is about 35 percent of the Sun's radius. Two planets revolve around the celestial body, and on the surface of one of them, hypothetically, liquid water can exist. This is a super-Earth GJ 273b with a mass of 2.9 Earths and an equilibrium temperature of -64 to 20 degrees Celsius.
The new series of posts contains an account of arithmetic, geometry and trigonometry, as well as time and chronometry - the latter should help to clarify how other civilizations understand time. In addition, 10-second excerpts of music tracks from the Spanish festival were included in the message. The performers included Jean-Michel Jarre, Keith Tempest, the Matmos duo and others.
The message is timed to coincide with the anniversary of the Arecibo message sent on November 16, 1974 to globular cluster M13. It contained information about the planets of the solar system, the structure of DNA, the appearance of a person, numbers, chemical elements and the Arecibo telescope, which served as a transmitter.
In April next year, the METI project will turn the EISCAT transmitter into a "musical instrument" and with its help will send 15 melodies into space. The signal will be transmitted on different radio frequencies at specific intervals, similar to the intervals between musical notes.
