NGC 4424 futhi Leda 213994

I-NGC futhi okuphikisana nalo yesimanje

Lesi sithombe-Hubble libonisa NGC 4424 futhi Leda 213994.

Umthala ngobukhulu kubonakala esithombeni is NGC 4424. ubukhulu +11.7 Umthala itholakala 30 abayizigidi ezingu-light-years away umlaza Virgo (The Virgin).

KWENU 213994, ezidlula +15.5, iyona Umthala ezincane futhi babaza esivela ngezansi NGC 4424.

okwenzeka +17.7 inkanyezi (USNOA2 0975-06963766) livela phakathi nendawo ephansi yesithombe.

Ngo 2012, yohlobo Ia Supernova wawukubona izazi zezinkanyezi ngo-NGC 4424. Supernova Wethiwa elika SN 2012cg. Ungabuka izithombe phansi-based SN 2012cg lapha.

Isithombe esingenhla yadalwa kusetshenziswa izithombe zangempela ethunjwa Hubble. Ngakwesobunxele kuyinto NGC 3310, a Umthala nge ngokwedlulele asebenzayo star kwetinhlavu. In isikhungo iyona SN 1006 Insali, a section elincanyana kusukela okusale a supernova ovela 1006 A.D. Umcimbi supernova. On ngakwesokudla VA 18059-3211, inkanyezi welanga efana Ngasekupheleni kokuphila yayo.

Hubble Ibona Spiral in Serpens

By

Lokhu entsha NASA / ESA Hubble Space Telescope image sikhombisa galaxy enhle Kuvunguza eyaziwa ngokuthi PGC 54493, etholakala iKhima of Serpens (INyoka). Lolu Umthala siyingxenye cluster galaxy eye ufundwa izazi zezinkanyezi ukuhlola buyinto ethakazelisayo aziwa ngokuthi ebuthakathaka lensing adonsela phansi.

Lokhu umphumela, okubangwa ukusatshalaliswa engalingani of udaba (kuhlanganise esimnyama) kulo lonke Universe, Kuye iyahlaziwa via vo ezifana Hubble Medium Deep Survey. Esimnyama ingenye ngezimfihlakalo mkhulu yonke. It eziphatha kakhulu ehlukile kusukela udaba ezijwayelekile njengoba akusho bungakhiphi noma simunce kukhanya noma ezinye izinhlobo zamandla kagesi - kungakho igama elithi “dark.”

Nakuba singeke agcine esimnyama ngqo, siyazi ikhona. One piece ovelele zobufakazi ukhona kule ndaba bekhethelo njengoba laziwa “Inkinga Ukujikeleza galaxy.” Imithala ukushintshanisa ngesivinini enjalo futhi ngendlela yokuthi udaba ezejwayelekile yedwa - izinto esizibona - ngeke akwazi ukubamba kwabo ndawonye. Inani mass okuwukuthi “abalahlekile” batshengise kuyinto esimnyama, okuyinto kucatshangwa ukwenza up abanye 27 amaphesenti okuqukethwe ingqikithi Universe, amandla amnyama kanye udaba evamile abakha ukuphumula. PGC 55493 iye wafunda mayelana nomphumela aziwa ngokuthi cosmic Shearing. Lokhu kuyinto ababuthakathaka adonsela phansi lensing ngomphumela kubanga Ukuhlanekezelwa amancane in images of imithala ekude.

Hubble ubheka Light and Dark in the Universe

By

Lokhu entsha NASA / ESA Hubble Space Telescope image sikhombisa ezihlukahlukene ezithakazelisayo imihlola cosmic.

Ezungezwe izinkanyezi bright, elibhekile maphakathi engenhla ifreyimu sibona into encane young lezinkanyezi (YSO) Eyaziwa ngokuthi SSTC2D J033038.2 303212. Etholakala iKhima of noPerseus, le nkanyezi okwamanje isesigabeni isencane futhi namanje ukwakha ibe star ngokugcwele emandleni. Kule mbono kusuka Camera Hubble sika Okuthuthukisiwe for abadabuli(ACS) kubonakala ukuba ube ushemula murky of material Uvivinyo olunjengomlilo outwards futhi phansi, anezinhlaka by Ukuvutha bright of gas ukugeleza inkanyezi ngokwayo. Lokhu star elisafufusa empeleni lizungezwe disk eliqhakazile ezingqubuzanayo ezaziyaluzisa ezingokwenyama bazungeza njengoba yakha - a disc ukuthi sibona emaphethelweni-on ngombono wethu.

Nokho, le uyichashaza elincane bright is dwarfed by umakhelwane walo cosmic elibhekile phansi ifremu, a isixhobo of bright, wispy gas ezingqubuzanayo ezaziyaluzisa nxazonke njengoba ibonakala ezikhafula material amnyama out emkhathini. Ifu elikhanyayo kuyinto esigaxeni reflection eyaziwa ngokuthi [B77] 63, ifu Igesi Interstellar ukuthi is ukukhanya okuvela ezinkanyezini linamathele zingakapheli it. Kukhona empeleni inani lezinkanyezi bright phakathi [B77] 63, ephawuleka kakhulu ekushayweni-line star LkHA 326, futhi umakhelwane oseduze LZK 18.

Lezi izinkanyezi babasa up igesi ezungezile bese sculpting ibe ijamo wispy kubonakala kulesi image. Nokho, ingxenye esimangalisa kunazo yesithombe ibonakala umfudlana emnyama intuthu enqwabelanisa outwards kusuka [B77] 63 nezinkanyezi zalo - a esigaxeni omnyama obizwa Dobashi 4173. Mafu Dark kukhona amafu ngendlela emangalisayo aminyene ezibonakalayo. pitch-amnyama ezifihla nezimagqabhagqabha of sky emva kwabo, ezibonakala ukudala URips ezinkulu kanye nezixhobo eerily ezingenalutho sky. Izinkanyezi amabhadubhadu phezu kwalesi kobumnyama obedlulele ngempela amanga phakathi kwethu Dobashi 4173.
