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.
