摘要
| 描述 |
English: This artist’s impression shows two galaxies in the early Universe. The brilliant explosion on the left is a gamma-ray burst. As the light from the burst passes through the two galaxies on the way to Earth (outside the frame to the right) some colours are absorbed by the cool gas in the galaxies, leaving characteristic dark lines in the spectrum. Careful study of these spectra has allowed astronomers to discover that these two galaxies are remarkably rich in heavier chemical elements. Русский: Это — художественное представление двух галактик ранней Вселенной. Блестящий взрыв слева — гамма-всплеск. Когда свет от вспышки по пути к Земле (расположена справа за кадром) проходит через две галактики, происходит его избирательное поглощение холодным газом галактик, в результате чего появляются характерные тёмные линии в спектре. Тщательное изучение этих спектров позволило астрономам обнаружить необычайно высокое содержание тяжелых элементов в данных галактиках. |

Italiano: Rappresentazione grafica di due galassie nelle prime fasi della formzione dell'universo. La brillante esplosione sulla sinistra è un esplosione di raggi gamma, lo studio del loro spettro evidenzia le frequenze dei colori che sono state assorbiti nell'attraversare le due galassie (le linee scure) nel loro viaggio verso la Terra. Ciò ha permesso agli astronomi di scoprire che queste due galassie sono eccezionalmente ricche di elementi pesanti. Nederlands: Deze artistieke impressie toont twee sterrenstelsels in het vroege heelal. De felle explosie aan de linkerkant is een gammaflits. Als het licht van de flits door de twee sterrenstelsels gaat op weg naar de Aarde (buiten het beeld naar rechts) worden een aantal kleuren geabsorbeerd door het koele gas in de sterrenstelsels, waardoor karakteristieke donkere lijnen in het spectrum ontstaan. Zorgvuldige bestudering van deze spectra heeft astronomen in staat gesteld te ontdekken dat deze twee sterrenstelsels opvallend rijk zijn aan zwaardere chemische elementen.
