OTD Precede – November 16: Arecibo Observatory Broadcasts Interstellar Message

.On Nov 16, 1974, humans delivered their 1st message to the stars in an effort to talk to space beings. They performed this using what was actually at that point the largest radio telescope on earth, found at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake and Carl Sagan delivered their information to the M13 galaxy.

The notification was actually recorded binary code and consisted of relevant information concerning human DNA. It likewise consisted of amounts of an individual, the solar system and the Arecibo telescope. The concept was actually that if any kind of aliens were to receive the sign and also find out exactly how to decode it, they would certainly know where it stemmed from.

Given that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any sort of M13 aliens to hear our message– if they are actually level there. The Arecibo information is only one of a number of notifications meant for extraterrestrials. Our team have additionally consisted of notifications on a number of spacecraft, including Pioneer as well as Voyager.
