"There was a sketch of a human being, our population was given, and planet three in the solar system sketch was displaced towards the human to indicate that’s where we lived."

The message. Note the human, radio dish, and solar system.

The Arecibo Observatory message was a message sent out by the members of Arecibo Observatory in November 19, 1974 to the globular star cluster M13[1] for a ceremony to mark the remodeling of the Arecibo radio telescope. The message consisted of 1679 binary digits (equivalent to nearly 205 bytes) transmitted at a frequency of 2380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 1000 kWatt. The beam was extremely narrow (giving a power equivalent to 20 trillion Watts if it were omnidirectional) making it the strongest man-made signal ever sent. It was meant to be picked up by extraterrestrials so that they could find Earth and locate the source of the message.[2] The leader of the project was Frank Drake, who also set up Project Ozma in 1960.[2]

TravelEdit

The message is still traveling through space as of today, and it is highly improbable that it has passed any stars with planets orbiting them. Even if it has passed an extrasolar planet, the odds are very slim that any intelligent, if that, organisms reside on the planet. And, by pushing it, it is even slimmer that the intelligent species has already advanced to picking up radio signals.[2] Since the destination, M13, is 25,000 light-years away from Earth, it will take 25,000 years for the signal to reach it.[3] The message was sent at about "a million times stronger than the typical TV transmission"[3]. It is stronger than the Sun's radio waves and could be recieved through technology similar to that of the radio telescopes of Earth.[3]

InterpretationEdit

"We eventually learned that nobody could interpret all of the message; each scientist only could interpret the part relevant to their discipline."
—Frank Drake(source)

When the signal was finished, scientists were asked if they could interpret the pictures and other objects in the message. Each scientist interpreted something different[4].

Actual readingEdit

The signal was made of several parts.

  • At the top, it reads the numbers 1-10, showing our number system[5]
  • Next, it shows the atomic numbers of several significant biological elements[5]
  • Formulas for several different chemicals[5]
  • The recognizable "double helix" of DNA[5]
  • A human, with the population and height defined beside him[5]
  • The Solar System, with Earth more upward[5]
  • The Arecibo dish[5]
