Nedir bu “Wow! Sinyali\u201d<\/b><\/p>\n

Ohio Eyalet \u00dcniversitesi’nin Big Ear radyo teleskobu, 1970’lerin ba\u015f\u0131ndan 1995’e kadar s\u00fcren, tarihin en uzun s\u00fcreli SETI <\/strong>program\u0131nda kullan\u0131ld\u0131. 1977 y\u0131l\u0131nda Big Ear, \u00e7ok \u00f6zel bir sinyal tespit etti: Wow! Sinyali. Bu sinyal, n\u00f6tr hidrojen frekans\u0131na \u00e7ok yak\u0131n, g\u00fc\u00e7l\u00fc bir dar bant radyo sinyaliydi. Big Ear teleskobu art\u0131k yok, ancak bu sinyalin ne oldu\u011fu konusundaki \u00e7al\u0131\u015fmalar devam ediyor.<\/p>\n

Sinyal, Big Ear’\u0131n g\u00f6zlemleyebildi\u011fi 72 saniyelik s\u00fcre boyunca s\u00fcrd\u00fc. Birka\u00e7 g\u00fcn sonra, astronom Jerry R. Ehman, bilgisayar \u00e7\u0131kt\u0131s\u0131nda bu sinyali g\u00f6rd\u00fc ve yan\u0131na “Wow!<\/strong>” yazd\u0131. Sinyal, bu isimle an\u0131lmaya ba\u015fland\u0131. Sinyalin bir di\u011fer ad\u0131 ise 6EQUJ5<\/strong>. Bu kod, sinyalin zaman i\u00e7indeki yo\u011funluk de\u011fi\u015fimini temsil ediyor.<\/p>\n

Baz\u0131lar\u0131 bu sinyalin d\u00fcnya d\u0131\u015f\u0131 bir kaynaktan geldi\u011fini d\u00fc\u015f\u00fcnd\u00fc, baz\u0131lar\u0131 ise bunun insan kaynakl\u0131 bir parazit olabilece\u011fini \u00f6ne s\u00fcrd\u00fc. Di\u011fer bir grup ise, bu sinyalin a\u00e7\u0131klanamayan do\u011fal bir fenomen oldu\u011funu iddia etti.<\/p>\n

Ancak yeni ara\u015ft\u0131rmalar, Wow! Sinyali’nin tamamen do\u011fal bir a\u00e7\u0131klamaya sahip oldu\u011funu g\u00f6steriyor.<\/p>\n

<\/span> Porto Riko \u00dcniversitesi Planetary Habitability Laboratory (Gezegensel Ya\u015fanabilirlik Laboratuvar\u0131) taraf\u0131ndan y\u00fcr\u00fct\u00fclen yeni ara\u015ft\u0131rma, Arecibo Radyo Teleskobu<\/strong>‘ndan 2017-2020 y\u0131llar\u0131 aras\u0131nda elde edilen verilerin ar\u015fiv \u00e7al\u0131\u015fmas\u0131na dayan\u0131yor. Yazarlara g\u00f6re Arecibo’dan gelen g\u00f6zlemler Big Ear’dan gelenlere benziyor ancak daha hassas, daha iyi zamansal \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011fe<\/strong> sahip ve<\/strong> polarizasyon \u00f6l\u00e7\u00fcmlerini<\/strong> i\u00e7eriyor<\/strong>. <\/figure>\n

2020 y\u0131l\u0131 \u015eubat ve May\u0131s aylar\u0131 aras\u0131nda yap\u0131lan son g\u00f6zlemlerin, hidrojen hatt\u0131na yak\u0131n, ancak orijinal Wow! Sinyalinden daha az yo\u011fun olan benzer dar bant sinyallerin varl\u0131\u011f\u0131n\u0131<\/strong> ortaya \u00e7\u0131kard\u0131\u011f\u0131 belirtiliyor. Ara\u015ft\u0131rmac\u0131lar, bu sinyallerin astrofiziksel bir fenomenle kolayca a\u00e7\u0131klanabilece\u011fini ve orijinal Wow! Sinyali’nin de bu \u015fekilde a\u00e7\u0131klanabilece\u011fini s\u00f6yl\u00fcyor.<\/p>\n

Buna g\u00f6re Ara\u015ft\u0131rmac\u0131lar, Wow! Sinyali’nin, g\u00fc\u00e7l\u00fc bir ge\u00e7ici radyasyon kayna\u011f\u0131<\/strong>, \u00f6rne\u011fin bir magnetar patlamas\u0131<\/strong> veya yumu\u015fak gama tekrarlay\u0131c\u0131<\/strong> (SGR, Soft Gamma Repeater) gibi, hidrojen hatt\u0131ndan uyar\u0131lm\u0131\u015f yay\u0131lma ile meydana gelen ani bir parlamadan kaynakland\u0131\u011f\u0131n\u0131 varsay\u0131yor. Bu olaylar\u0131n hassas ko\u015fullar ve hizalanmalar alt\u0131nda nadiren oldu\u011funa dikkat \u00e7ekiliyor. Bu \u015fartlar sa\u011fland\u0131\u011f\u0131nda hidrojen bulutlar\u0131n\u0131n birka\u00e7 saniye veya dakika boyunca \u00f6nemli \u00f6l\u00e7\u00fcde parlamas\u0131 m\u00fcmk\u00fcn oluyor.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, 1977’de Big Ear’\u0131n g\u00f6rd\u00fc\u011f\u00fc \u015feyin, teleskopun g\u00f6r\u00fc\u015f alan\u0131ndaki birka\u00e7 n\u00f6tr hidrojen (H1) bulutundan birinin ge\u00e7ici parlamas\u0131 oldu\u011funu s\u00f6yl\u00fcyor. 1977 sinyali, bir\u00e7ok a\u00e7\u0131dan Arecibo’nun g\u00f6rd\u00fc\u011f\u00fc sinyallere benziyordu. Arecibo’da g\u00f6zlemlenen sinyaller ile Wow! Sinyali aras\u0131ndaki tek fark\u0131n parlakl\u0131klar\u0131 oldu\u011fu<\/strong> aktar\u0131l\u0131yor.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, sinyalden sorumlu bulutlar\u0131 tan\u0131mlayabildiler ancak kayna\u011f\u0131 belirleyemediler. Sonu\u00e7lar, kayna\u011f\u0131n hidrojen sinyalini \u00fcreten bulutlardan \u00e7ok daha uzakta oldu\u011funu g\u00f6steriyor. Ancak ek analizler ile kesin konum tespitinin m\u00fcmk\u00fcn oldu\u011funu s\u00f6yl\u00fcyor ara\u015ft\u0131rmac\u0131lar. Wow! Sinyali ba\u015flang\u0131\u00e7ta bir\u00e7ok ki\u015fi taraf\u0131ndan teknolojik bir imza olarak yorumlanm\u0131\u015ft\u0131. Bu ara\u015ft\u0131rma ise sinyalin nereden geldi\u011fini a\u00e7\u0131klayarak durumun bir yanl\u0131\u015f alarm oldu\u011funu ortaya koyuyor.<\/p>\n\n
