The Arecibo message as decoded into 23 rows and 73 columns. Although unintelligible, the message in this format appears sufficiently organized to show that it is not a random signal. The last part is a graphic representing the Arecibo radio telescope and indicating its diameter with a binary representation of the number 2,430; multiplying by ...
These seven messages have targeted stars between 20 and 69 light-years from the Earth. The exception is the Arecibo message, which targeted globular cluster M13, approximately 24,000 light-years away. The first message to reach its destination will be A Message From Earth, which should reach the Gliese 581 planetary system in Libra in 2029.
Frank Drake (SETI Institute): SETI pioneer, composed the Arecibo message. Dr John Elliott: research into developing strategies, which are based on receiving a 'natural' language message, that look at developing algorithms to detect if an ET signal has intelligent-like structure and if so, then how to decipher its content.
The plaque was the first physical message sent into space and intended to be understandable by any sufficiently technologically advanced extraterrestrial lifeforms that might intercept it. [11] In 1974, Drake wrote the Arecibo message, the first interstellar message transmitted deliberately from Earth. [12]
The 1974 Arecibo message, which contained encoded information about the human race, DNA, atomic numbers, Earth's position and other information, was beamed from the Arecibo Observatory radio telescope towards Messier 13 as an experiment in contacting potential extraterrestrial civilizations in the cluster.
The image is not intended to be an exact representation of the original message, it is just for making it easy for readers to easily understand different parts of the message, IMO. The original message is just a series of "1s" and "0s" (in binary) and does not make sense for most readers (so, I think we need a picture and therefore we have to ...
Cosmic Call was the name of two sets of interstellar radio messages that were sent from RT-70 in Yevpatoria, Ukraine in 1999 (Cosmic Call 1) and 2003 (Cosmic Call 2) to various nearby stars. The messages were designed with noise-resistant format and characters.
The exception is the Arecibo message, which targeted globular cluster M13, approximately 24,000 light-years away. The first interstellar message to reach its destination was the Altair (Morimoto - Hirabayashi) Message, which likely reached its target in 1999.
