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.
