For years, humans have tried to make contact with extraterrestrial life.
In 1974, SETI used the Arecibo telescope in Puerto Rico to target the M13 cluster of stars, about 25,000 light years away. In other projects, transmissions were sent to bright or well-known stars like the Polaris and Altair stars, or stars with giant exoplanets that are less likely to be habitable, similar to Jupiter.
Also, the twin Voyager spacecrafts, launched in 1977, carried 12-inch gold-plated copper phonograph records into interstellar space, containing sounds and images from Earth, like music from Bach, Chuck Berry, Mozart and Beethoven, as well as songs from Pygmy, Aborigine and Navajo tribes.
What makes this project different is that the transmission targeting a specific planet that may be habitable. Luyten Star b resides in the habitable zone, the distance from a star where a planet could potentially have liquid water — it’s not too close, so the surface won’t be too hot, and it’s not too far that any liquid would freeze over.
