Glossary term: Inteligencia extraterrestre
Description: La inteligencia extraterrestre se refiere a la posible existencia de entidades inteligentes distintas de las que hay en la Tierra.
La búsqueda de inteligencia extraterrestre ha incluido la búsqueda de señales de radio u otras señales, pero gran parte de la investigación actual se centra en determinar si en otros lugares se dan las condiciones necesarias para la vida inteligente. A juzgar por las pruebas disponibles, las condiciones necesarias para la aparición de la vida en la Tierra —un planeta sólido, situado a una distancia de su estrella que permita la existencia de agua líquida en la superficie del planeta, átomos como el carbono y el oxígeno, y las condiciones para formar moléculas más complejas— deberían darse en numerosos planetas de nuestra Galaxia y más allá. No es descabellado suponer que podría haber surgido vida inteligente al menos en algunos de esos planetas, aunque no disponemos de una base sólida para estimar la probabilidad de que eso ocurra.
Algunos astrónomos han utilizado señales de radio para buscar posibles mensajes en el marco del programa de Búsqueda de Inteligencia Extraterrestre (SETI por sus siglas en inglés). La velocidad de la luz, como límite físico fundamental, implica que los viajes interestelares llevarían mucho tiempo, lo que limita nuestra capacidad para entrar en contacto directo con inteligencias extraterrestres.

Arecibo Message
Caption: This image shows a representation of an interstellar radio message, known as the “Arecibo Message”. As part of this visualisation different parts are highlighted by different colors. It was sent on the 16th of November in 1974 from the Arecibo Telescope in Puerto Rico, at this time the largest radio telescope on Earth, on the 16th of November in 1974. Its destination was the globular cluster M13 in the constellation of Hercules. M13 is one of the brightest of its kind, contains about half a million stars and is located at a distance of approximately 25 000 light years. It was chosen as a target because of its dense stellar population, meaning the message would reach more stars and hopefully planets. Moreover, it is one of the nearer globular clusters available in the sky at the time and place when the message was sent.
The Arecibo Message was a symbolic event, intended to show that humans could broadcast a message to the stars. The message contains 1679 (chosen as it is the product of two prime numbers) bits of data which, when arrange in a two dimensional array, form the image shown here. It consists of seven parts which contain representations of DNA, a human, and information on the Earth and Solar System. The message content was designed by a group of scientists from Cornell University and the Arecibo Observatory.

Pioneer Plaques
Caption: The Pioneer 10 and 11 spacecraft are the first human-made objects to leave the solar system and venture into interstellar space. To inform potentially intelligent species about our existence, they both carry small metal plaques identifying their time, place of origin and information about their builders. They provide the location of our solar system in the Milky Way by depicting the Solar System's position relative to 14 pulsars, with radiating lines that include information about their frequencies. A model of a hydrogen atom undergoing one particular atomic transition is depicted. The wavelength and frequency of this transition are used to express sizes and frequencies of the other items shown in the plaque. A more detailed view of Earth's position in the solar system, with the spacecraft's trajectory moving away from Earth, passing Mars and Jupiter is displayed at the bottom. The plaque also depicts a naked man and woman alongside the spacecraft to provide a sense of scale. The man’s hand is raised as a friendly gesture.
The 6-inch by 9-inch gold-anodized aluminum plate has the design engraved on it. It was attached to the support struts of the spacecraft's antenna to try to to protect it from erosion by any interstellar dust the spacecraft may encounter on its journey. Designed by Carl Sagan and Frank Drake, with artwork by Linda Salzman Sagan, these plaques are meant to communicate the origin of the spacecraft to any extraterrestrial life that might encounter them.
While Pioneer 10 is on a course towards the star Aldebaran in the Taurus constellation, which will take about two million years to reach, Pioneer 11 is heading in a different direction towards the constellation of Aquila. It will take approximately four million years to pass close to some of the constellation’s stars.
