.On November 16, 1974, people sent their first message to the stars in a try to get in touch with space beings. They performed this using what was actually at that point the largest radio telescope worldwide, situated at the Arecibo Observatory in Puerto Rico. A team of researchers led through Frank Drake as well as Carl Sagan delivered their notification to the M13 star cluster.
The message was recorded binary code and had info concerning human DNA. It likewise included numbers of an individual, the planetary system and also the Arecibo telescope. The suggestion was that if any type of invaders were to acquire the signal and also determine just how to decode it, they will recognize where it arised from.
Because M13 is actually 25,000 light-years away, it will take 25,000 years for any kind of M13 invaders to hear our information– if they are actually flatten there certainly. The Arecibo notification is a single of a number of notifications meant for extraterrestrials. Our team have likewise included notifications on many spacecraft, like Pioneer and Voyager.
