Wow! signal
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.
Categorie: Kosmologie
De verre uiteinden, het ontstaan en uitdijen van de kosmos hebben me altijd al geboeid. En er zijn raakvlakken met andere categorieën: buitenaards en wis- en natuurkunde.
Universe calling Earth
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.
Where is everybody?
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.
The Pioneer Plaque impact
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.
Talking to Aliens?!
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.
How Scientists Could Tell the World if They Find Alien Life
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.
Geschiedenis van de Kosmologie
Zoals in de vorige bijdrage beschreven is ongeveer 95% van de materie en energie in onze kosmos nog ongedefinieerd ofwel “dark“. Laten
