    Summary

    Description
    Afrikaans: 'n Bekoorlike beeld van die helder Chileense hemelruim oor 'n sterrewag. Dit toon die vierde (Yepun genoem) van vier eenheidteleskope van die Baie Groot Teleskoop (BGT), met as agtergrond 'n breë sterreveld met helder sterre en afgeleë sterrestelsels. Die sterreveld bestaan hoofsaaklik uit die Andromeda-, Triangulum- en Perseus-sterrebeelde. Enkele objekte in hierdie sterreveld is meer bekend as die aanliggendes:
       In die linkerstrook van die beeld is 'n redelik prominente sterrestelsel sigbaar as 'n langwerpige kwasstrepie oor die donker naglug, naamlik Messier 31, oftewel die Andromedasterrestelsel. Na bo en regs hiervan is 'n helder ster (μ Andromedae), en langs dieselde lyn boontoe lê die ster β Andromedae – ook Mirach genoem – asook 'n tweede sterrestelsel, die Driehoek-sterrestelsel (Messier 33) teen die boonste rand van die beeld. Dit word vermoed dat hierdie twee sterrestelsels voorheen 'n aksie op mekaar uitgeoefen het, sodat daar steeds 'n brug van waterstofgas tussen die twee mag bestaan. Ook opvallend is die ster Almach net bo die teleskoop, die oop sterreswerm M 34 effens regs daarvan, en die helder sterre Algol (middel) en Mirfak (onder), in die regterbaan van die beeld.
       Perseus, seun van Zeus en Danaë, sou vir skone Andromeda, dogter van koningspaar Cepheus en Cassiopeia, voor 'n seemonster weggeraap het, en die nageslag van hierdie heldepaar sou die Perse en Spartane oplewer. M 31 is gesetel by Andromeda se regterheup, en Mirach dui haar "gordel" of "lendekleed" aan. Almach is 'n "rooikat" wat by haar voet onderskei word. Mirfak vorm die "ellemboog" van Perseus, en Algol die kop van die verslane gorgoon-demoon.

    Русский: На этом замечательном снимке – яркие звезды и галактики на ясном чилийском небе над одним из четырех восьмиметровых Базовых Телескопов (UT), составляющих Очень Большой Телескоп VLT. Это UT под номером четыре, по имени Йепун, что на языке индейцев-аборигенов означает Венеру.

    Два объекта на этом фото больше известны, чем их соседи. В левой части снимка хорошо заметна галактика в виде яркой косой полоски: Мессье 31, или туманность Андромеды. Вверху справа от нее – яркая звезда, а дальше на продолжении той же прямой линии, идущей вверх и направо, видна еще одна галактика. Звезда – это бета Андромеды (Мирах), а вторая галактика – Мессье 33 (в верхней части снимка). Предполагается, что в далеком прошлом эти галактики взаимодействовали друг с другом и пространство между ними заполнял «мост» из газообразного водорода.

    English: This stunning image of the clear Chilean sky shows a speckling of bright stars and distant galaxies across the frame, all suspended above one of the four Unit Telescopes (UTs) of the Very Large Telescope (VLT). This is the fourth UT and it is known as Yepun (Venus).

    Two objects seen in this frame are more famous than their neighbours. In the left hand portion of the image is a fairly prominent galaxy that forms a streak across the sky – Messier 31, or the Andromeda Galaxy. Upwards and to the right of this smudge is a bright star, which in turn points upwards to a galaxy that lies roughly along the same extended line. This star is named Beta Andromedae – otherwise known as Mirach – and the second galaxy is Messier 33 (at the top of the frame). These two galaxies are thought to have interacted in the past, forming a bridge of hydrogen gas that spans the gap between them.
