Bilim<\/a> insanlar\u0131, \u015fu anda G\u00fcne\u015f Sistemi’nin i\u00e7ine do\u011fru h\u0131zla ilerleyen devasa bir kuyruklu y\u0131ld\u0131z\u0131 g\u00f6zlemliyor. G\u00f6k cismi neredeyse kelimenin tam anlam\u0131yla \u201cbuhar g\u00fcc\u00fcyle\u201d geliyor. G\u00f6kbilimciler, cismin y\u00fczeyinden b\u00fcy\u00fck miktarda karbonmonoksit gaz\u0131 p\u00fcsk\u00fcrd\u00fc\u011f\u00fcn\u00fc tespit etti.<\/p>\n

UN271 (Bernardinelli-Bernstein olarak da biliniyor) adl\u0131 kuyruklu y\u0131ld\u0131z, \u015fimdiye kadar Oort Bulutu’ndan gelen en b\u00fcy\u00fck kuyruklu y\u0131ld\u0131z olarak da biliniyor. \u00c7ap\u0131 yakla\u015f\u0131k 137 kilometre, yani dinozorlar\u0131 yok eden asteroitten yakla\u015f\u0131k 14 kat daha b\u00fcy\u00fck.<\/p>\n

Bu dev cisim kula\u011fa \u00fcrk\u00fct\u00fcc\u00fc gelse de D\u00fcnya i\u00e7in bir tehlike olu\u015fturmuyor. Kuyruklu y\u0131ld\u0131z, 29 Ocak 2031 tarihinde Sat\u00fcrn y\u00f6r\u00fcngesine kadar yakla\u015facak ancak daha i\u00e7eri ilerlemeyecek.<\/p>\n

\u0130K\u0130 GAZ JET\u0130 G\u00d6ZLEMLEND\u0130<\/h3>\n

Ara\u015ft\u0131rmac\u0131lar, \u015eili’deki Atacama B\u00fcy\u00fck Milimetre\/Milimetre-alt\u0131 Dizisi (ALMA) teleskobunu kullanarak kuyruklu y\u0131ld\u0131z\u0131n b\u00fcy\u00fckl\u00fc\u011f\u00fcn\u00fc do\u011frulad\u0131 ve molek\u00fcler faaliyetlerini g\u00f6zlemledi.<\/p>\n

NASA Goddard Uzay<\/a> U\u00e7u\u015f Merkezi ve Amerikan \u00dcniversitesi\u2019nden astrokimyager Nathan Roth, “Bu \u00f6l\u00e7\u00fcmler, bu devasa buzlu cismin nas\u0131l \u00e7al\u0131\u015ft\u0131\u011f\u0131na dair bize yeni bir pencere a\u00e7\u0131yor” dedi.<\/p>\n

ALMA, s\u00f6z konusu kuyruklu y\u0131ld\u0131z\u0131 8 ve 17 Mart 2024 tarihlerinde g\u00f6zlemledi. \u0130lk g\u00f6zlem, bir patlaman\u0131n hemen sonras\u0131na denk geldi\u011fi i\u00e7in daha fazla aktivite saptand\u0131.<\/p>\n

8 Mart’ta, kuyruklu y\u0131ld\u0131z\u0131n \u00e7ekirde\u011finden f\u0131rlayan iki gaz jeti tespit edildi. Spektrometre analizleri, bu jetlerin b\u00fcy\u00fck oranda karbonmonoksit i\u00e7erdi\u011fini ortaya koydu. Ayn\u0131 zamanda kuyruklu y\u0131ld\u0131zlar\u0131n karakteristik \u00f6zelli\u011fi olan “koma” (gaz ve tozdan olu\u015fan kuyruklar) da olu\u015fmaya ba\u015flam\u0131\u015ft\u0131.<\/p>\n

Ancak 17 Mart\u2019ta yap\u0131lan ikinci g\u00f6zlemde, sadece bir jet aktifti ve komaya dair bir iz kalmam\u0131\u015ft\u0131. Bilim insanlar\u0131 di\u011fer jetin, kuyruklu y\u0131ld\u0131z d\u00f6nd\u00fc\u011f\u00fc i\u00e7in g\u00f6r\u00fc\u015f alan\u0131ndan \u00e7\u0131km\u0131\u015f olabilece\u011fini belirtiyor.<\/p>\n

GAZ JETLER\u0130 \u0130LK KEZ NET G\u00d6ZLEMLEND\u0130<\/h3>\n

Bu \u00e7al\u0131\u015fma, UN271\u2019ten \u00e7\u0131kan gaz jetlerinin ilk kez net \u015fekilde g\u00f6zlemlenmesi anlam\u0131na geliyor. Dahas\u0131, tespitler epey uzak bir mesafeden yap\u0131ld\u0131: O s\u0131rada kuyruklu y\u0131ld\u0131z, Uran\u00fcs y\u00f6r\u00fcngesi civar\u0131nda, yani D\u00fcnya-G\u00fcne\u015f mesafesinin yakla\u015f\u0131k 16 kat\u0131 \u00f6tedeydi.<\/p>\n

UN271\u2019in \u00e7ekirde\u011fi daha \u00f6nce de yakla\u015f\u0131k 137 kilometre olarak tahmin edilmi\u015fti, bu da onu d\u0131\u015f G\u00fcne\u015f Sistemi\u2019ni saran buzlu cisimler ku\u015fa\u011f\u0131 Oort Bulutu’ndan \u00e7\u0131kan en b\u00fcy\u00fck kuyruklu y\u0131ld\u0131z yap\u0131yor. \u00d6nceki rekorun sahibi olan Hale-Bopp\u2019un boyutunun iki kat\u0131ndan daha b\u00fcy\u00fck.<\/p>\n

Ancak bu \u00f6zellikler, onu t\u00fcm zamanlar\u0131n en b\u00fcy\u00fck kuyruklu y\u0131ld\u0131z\u0131 yapmaya yetmiyor. Bu unvan, 95P\/Chiron adl\u0131 ve 210 kilometre \u00e7ap\u0131nda olabilece\u011fi d\u00fc\u015f\u00fcn\u00fclen kuyruklu y\u0131ld\u0131za ait. Neyse ki Chiron, G\u00fcne\u015f Sistemi\u2019nde hareket eden bir nesne de\u011fil; Sat\u00fcrn ve Uran\u00fcs aras\u0131nda sabit bir y\u00f6r\u00fcngede dolan\u0131yor.<\/p>\n

UN271 G\u00fcne\u015f\u2019e yakla\u015ft\u0131k\u00e7a bilim insanlar\u0131 \u00f6n\u00fcm\u00fczdeki y\u0131llarda onu daha yak\u0131ndan izlemeye devam edecek. G\u00f6rsel olarak etkileyici bir g\u00f6ky\u00fcz\u00fc \u015f\u00f6leni sunmas\u0131 bekleniyor, ancak ne yaz\u0131k ki \u00e7\u0131plak g\u00f6zle g\u00f6r\u00fclemeyecek kadar uzakta kalacak.<\/p>\n<\/div>\n
