Scientists suggest protocol for messaging to aliens

Scientists suggest protocol for messaging to aliens

July 13, 2011 - (PhysOrg.com) -- In 1974, humans broadcast the first message targeted at extraterrestrial life using the Arecibo radio telescope in Puerto Rico. The message, which was aimed at the globular star cluster M13 positioned 25,000 light years absent, consisted of binary digits that encoded data about our DNA, as properly as graphics of a human, our Solar System, and the Arecibo telescope. Since then, human beings have sent three other messages to nearby stars and planets (20-sixty nine light-years absent). These messages have turn into more complex and anthropocentric, with songs, images, and drawings submitted by the public.

Now a workforce of scientists, Dimitra Atri from the College of Kansas, Julia DeMarines from the International Space College in France, and Jacob Haqq-Misra from Pennsylvania State College, has proposed that long term attempts of messaging to extraterrestrial intelligence (METI) must follow a common protocol to increase communication success. They assume that some of the content material of previous METI broadcasts, which have sights and sounds, would probably go unnoticed by extraterrestrials who do not have visual or auditory perception (like some organisms on Earth). Rather, the scientists argue that brief, easy messages with nominal anthropocentrism, and which rely on basic physical or mathematical language, have the very best possibility of results.

In their examine, which will be published in a long term concern of Space Coverage, the researchers say that a METI protocol really should offer constraints and suggestions for variables such as sign encoding, message duration, details subject material, anthropocentrism, transmission method, and transmission periodicity.
