• Resumen

  • A radio message is winging its way to a neighboring star system that could contain a potentially habitable planet. So close is the star that a reply is even possible within 25 years. The message was sent on the anniversary of the Arecibo message, a radio transmission beamed towards a distant star cluster in 1974. That message held information on the planets of our solar system, the structure of DNA and a cartoon-like picture of a human being. The new message--beamed from Norway over a three-day period in October--is simpler and may be more readily understood. It includes information about maths, details on the radio waves that carry the message and a tutorial on clocks and timekeeping, to see if any potential inhabitants of GJ 273b understand time as we do.
