For a long time I have been giving scientific lectures in different countries and on diverse topics, generally related to astronomy and to my work at the Arecibo Observatory. No matter which parti- lar topic I am talking about, the same question always comes up: Have we had any contact at Arecibo with “them”? My negative answer does not satisfy anyone. In fact, the answer either confirms their suspicions that there is a conspiracy afoot by higher autho- ties not to release information or their intentions to deceive the general public. The reasons for the deception have to do with the idea that, as in the movie Contact, the received messages contain important and useful information that will bring great advantage to whoever gets it. Many of us want to believe that extraterrestrial creatures can talk to us, that perhaps they are even living among us, as UFO fans believe. It would be fascinating if it were true, a more than extra- dinary discovery, the answer to an eternal question. There is p- sibly a deep psychological motive in this desire to know if we are alone in this huge universe, and the need to believe in something beyond our limited world, in space and time. There is no doubt, then, that this topic brings with it many scientific and philosophical discussions, as well as speculations that, on many occasions, fall into pure pseudoscience because of the lack of a reference framework.

(Courtesy of the AOES Medialab, ESA 2002.) But how is the possession of a giant satellite related to the origin of life? To begin with, the Moon causes the tides. The life cycles of many coastal species depend on the ebb and flow of the tides. Furthermore, some theories on the appearance of life state that the changes in chemical concentrations brought about by the tides in coastal areas were indispensable for life to emerge on Earth. For example, one of these theories affirms that the prebiotic.
Due to the fact that water, or better said, water-ice, is the most evident feature of that world, with ice covering this interesting satellite completely, turning it into a smooth white ball. From the 1980s, it has been postulated that the tidal forces that Jupiter exerts on Europa, although not as powerful as those of Io (Europa is farther from Jupiter), could warm up the interior of this satellite enough to maintain water in a liquid state under the ice layer. Recently, two interesting.

Lincos’s structure is designed in such a way that it is a language that teaches itself, and given that actions speak louder than words, what could be better than learning to speak a little of.
