Chophimba Chophimba
Chophimba Chophimba ndi mtambo wa mpweya wotentha ndi wa ionized ndi fumbi mu gulu la nyenyezi.[1] Zimapanga mbali zooneka za Cygnus Loop,[2] otsalira a supernova, mbali zambiri zomwe zapeza mayina awo awo ndi zizindikiro zawo. Gwero la supernova linali nyenyezi zochulukitsa kawiri kuposa Dzuwa, lomwe linaphulika zaka pafupifupi 8,000 zapitazo. Zakale zowonjezereka zakhala zikuwonjezeka kuti zikhale ndi dera la madigiri pafupifupi madigiri atatu (pafupifupi 6 kuchuluka kwake, kapena malo okwana 36, a Mwezi wathunthu). Dera la nebula silidziwika bwino, koma deta ya Far Ultraviolet Spectroscopic Explorer (FUSE) imathandizira mtunda wa pafupifupi 1,470 kuwala-zaka.[3]
The Hubble Space Telescope inagwiritsa ntchito zithunzi zambiri za chithunzicho. Kufufuza kwa mpweya wochokera ku nebula kumasonyeza kukhalapo kwa mpweya, sulfure, ndi hydrogen.[4] Mtundu wa Cygnus Loop umatsitsimutsa kwambiri mafunde a radio ndi x-ray. Pa September 24, 2015 zithunzi ndi mavidiyo atsopano a Chophimba Chophimba anatulutsidwa, ndi kufotokoza kwa mafano.[5] with an explanation of the images.[6]
Kusamala
SinthaniNyuzipepalayi inapezedwa pa 1784 September 5 ndi William Herschel. Iye anafotokoza kumapeto kwakumapeto kwa chithunzicho monga "Kuwonjezera; kudutsa thro" 52 Cygni ... pafupi ndi 2 digiri m'litali ", ndipo anafotokoza mapeto a kummawa monga" Branching nebulasity ... Gawo lotsatira likugawa mitsinje yambiri ikugwirizananso kwa kum'mwera. "
Mukakonzekera bwino, mbali zina za fanoyo zimawoneka ngati zingwe zamtundu. Mafotokozedwe ofanana ndi akuti mafunde akudyeka kwambiri, osachepera gawo limodzi mu 50,000, kuti chipolopolocho chiwoneke pokhapokha ngati chimawoneka bwino, ndikupangitsa kuti chigoba chiwoneke. Popeza anapatsidwa mtunda wa zaka zapakati pa 1470, izi zimapereka mpata wa mzere wonse wa zaka 38.5 (m'lifupi lonse, zaka zapumulo 77). Pakati pa 1 / 50,000th, kumakhala makulidwe a mtunda wa makilomita 4 biliyoni, kapena kutali ndi Pluto. Kuthamangitsidwa pamwamba pa chipolopolo kumapangitsa mafano ambirimbiri, omwe amawoneka kuti akuphatikizana.
Ngakhale kuti nthendayi ili ndi kukula kwakukulu kwa 7, imafalikira pamtunda waukulu kwambiri moti kuwala kwake kumakhala kochepa kwambiri, choncho nthitiyi imadziwika kwambiri pakati pa akatswiri a zakuthambo monga zovuta kuziwona. Komabe, munthu amene amamuona amatha kuona chithunzicho mu telescope pogwiritsa ntchito fyuluta ya OIII (fyuluta yomwe imachokera kutalika kwa kuwala kochokera ku oxygen iwirizedoni), pafupifupi pafupifupi kuwala konse kochokera ku chithunzichi kumachokera pa kutalika kwake. Tulofoni ya masentimita 200 (200 mm) yokhala ndi fyuluta ya OIII ikuwonetseratu zojambulazo zooneka bwino m'zithunzi, ndipo ndi fayilo ya OIII pafupifupi pafupifupi telescope iliyonse ikuoneka kuti ikuwona chithunzichi. Ena amanena kuti izo zimawoneka popanda chithandizo chilichonse chowonekera kupatulapo fyuluta ya OIII yomwe imagwiritsidwa ntchito pa diso.
Zigawo zowoneka bwino za Nebula zili ndi zilembo za New General Catalog NGC 6960, 6974, 6979, 6992, ndi 6995. Chigawo chophweka chomwe mungapeze ndi 6960, chomwe chimayang'ana kumbuyo kwa nyenyezi yosasamala 52 Cygni. NGC 6992/5 ndi zinthu zosavuta kumbali yakumpoto ya chigawo. NGC 6974 ndi NGC 6979 zikuwoneka ngati zigawo zosiyana siyana m'mphepete mwa nebulosity kumpoto kwa kumpoto. Triangle ya Pickering ndi fainter yambiri, ndipo alibe nambala ya NGC (ngakhale 6979 nthawi zina amagwiritsidwa ntchito kutanthawuza). Anadziwika ndi photographically mu 1904 ndi Williamina Fleming (atatha kulembedwa kwa New General Catalog), koma Charles Krakering, yemwe anali mkulu wa katswiri wa zofufuza zapamwamba, ankachita mwambo umenewu.
