Al meer dan een decennium vonden de Amerikaanse verslagen van vreemde waarnemingen hun weg naar het catalogiseren en onderzoeken van tal van bizarre ontmoetingen – niet-geïdentificeerde luchtfenomenen, of UAP (een alternatieve term met aanzienlijk minder stigma dan de veel verguisde “UFO’s”).
Eind 2017 haastten astronomen over de hele wereld zich om een raadselachtige interstellaire bezoeker – de eerste ooit gezien – te bestuderen, De “gast” kwam kortstondig binnen het bereik van hun telescopen. De ontdekkers van het object noemden het ‘Oumuamua, een Hawaiiaanse term die zich ruwweg vertaalt naar ‘verkenner’. Het was de eerste “bezoeker” van buiten ons zonnestelsel.
In een vorige blog besprak ik de Breakthrough Initiatives en hun Breakthrough Listen Candidate 1. Dit buitenaardse signaal uit de regio Proxima Centauri was echter niet het eerste.
Eerder was er de Wow! signaal.
Er komen vreemde radiosignalen uit het dichtstbijzijnde sterrenstelsel en wetenschappers proberen te achterhalen wat deze betekenen. De signalen komen nooit van buitenaardse wezens, totdat is aangetoond dat het wel zo is.
In the book “Aliens: the World’s leading scientists in search for extraterrestrial life” by Jim Al Khalili I read the following anecdote of one of those leading scientists: Enrico Fermi.
In Carl Sagan’s publication Cosmic Connection (1975) he reveals some of the background and impact of the design of the Pioneer 10 and 11 plaque. Below we publish some excerpts from this publication.
In 1932, Karl Jansky serendipitously observed radiation coming from the Milky Way at Bell Labs, thereby inaugurating the science of radio astronomy. By this point, the evidence that humans were the only intelligent species in the solar system was mounting, but Jansky’s breakthrough turned the entire galaxy into fertile hunting grounds for extraterrestrial life.
In 1961, nine of the smartest individuals in the United States received a rather unusual letter in the mail. It consisted of a long string of binary digits and a short message: “Here is a hypothetical message received from outer space. It contains 551 zeros and ones. What does it mean?” Neither the sender nor his recipients knew it at the time, but this letter would later serve as the prototype for the first message for extraterrestrial intelligence ever broadcast into space. Its initial test run on Earth, however, was a total failure.
Relatively soon, some prominent astrobiologists say, we will most likely have either found compelling evidence for extraterrestrial life or banished its possible existence to the ever shrinking edges of the cosmos beyond the rapidly expanding reach of our observations. Such answers could come by the end of the 2030s from any of a number of initiatives ardently seeking alien life.
The belief in alien encounters has long been a prominent feature of American life. A 1997 poll from CNN/Time on the 50th anniversary of the Roswell incident found that 80% of Americans think the government is hiding knowledge of the existence of extraterrestrial life forms.
