Bu H II b\u00f6lgesi, yans\u0131ma<\/a> ve emisyon bulutsular\u0131<\/a> IC 59 ve IC 63’\u00fc i\u00e7erir.  Her iki bulutsunun da kuyruklu y\u0131ld\u0131z \u015feklinde bir yap\u0131s\u0131 vard\u0131r ve IC 63, ikisi aras\u0131nda daha parlak olan\u0131d\u0131r.  \u0130ki bulutsunun g\u00f6r\u00fcn\u00fcm\u00fcndeki farkl\u0131l\u0131k, \u03b3 Cas’tan olan fiziksel uzakl\u0131klar\u0131n\u0131n bir sonucudur. IC 63, iyi tan\u0131mlanm\u0131\u015f bir iyonizasyon cephesi sergilerken, bu IC 59’da yoktur.  Bulutsular, G\u00fcne\u015f’e en yak\u0131n fotodisosyasyon b\u00f6lgeleridir . <\/a><\/p>\n\n\n\n

Bu bulutsu, Alman g\u00f6kbilimci Max Wolf<\/a> taraf\u0131ndan 30 Aral\u0131k 1893’te ke\u015ffedildi  ve 1895’te JLE Dreyer’in<\/a> Bulutsular \u0130ndeks Katalo\u011fu’na<\/em><\/a> eklendi  A\u00e7\u0131sal boyutu \u015fu kadard\u0131r:10 \u2032<\/a> ve k\u00fc\u00e7\u00fck bir teleskopla g\u00f6r\u00fclebilir.  D\u00fcnya perspektifinden bak\u0131ld\u0131\u011f\u0131nda, IC 59, \u03b3 Cas’\u0131n \u00f6n\u00fcnde konumlanm\u0131\u015ft\u0131r ve y\u0131ld\u0131za en yak\u0131n ucu 13,5 \u0131\u015f\u0131k y\u0131l\u0131 (4,15 pc) uzakl\u0131kta yer almaktad\u0131r. Bu, \u03b3 Cas taraf\u0131ndan \u015fekillendirilen bir fotodissosiasyon b\u00f6lgesidir<\/a> . Y\u0131ld\u0131zdan gelen \u0131\u015f\u0131k, bulutsudan D\u00fcnya’ya do\u011fru 17\u00b0’lik bir a\u00e7\u0131yla sa\u00e7\u0131lmaktad\u0131r. <\/p>\n\n\n\n

Bulutsunun ucu \u03b3 Cas’a en yak\u0131n nokta olarak kabul edilse de, en yo\u011fun UV radyasyonu bat\u0131daki i\u00e7b\u00fckey y\u00fczeyden al\u0131nmaktad\u0131r. Bu nedenle u\u00e7, bulutunun geri kalan\u0131ndan y\u0131ld\u0131za daha uzakta olabilir. Bu bulutsunun daha s\u0131cak bile\u015feninin ortalama s\u0131cakl\u0131\u011f\u0131 \u015f\u00f6yledir:675 \u00b1 49 K , so\u011futucu bile\u015fen ise150 \u00b1 34 K .<\/p>\n\n\n\n
