摘要

描述
English: This map of a section of the Universe shows the positions of thousands of galaxies that were measured as part of the VIPERS survey with ESO’s Very Large Telescope. The observer on the Earth is at the left and galaxies towards the right are seen at earlier times in the history of the Universe. Redshift 0.65 corresponds to looking back about six billion years and redshift 1.0 to about eight billion years ago. The colours indicate the true colours of the galaxies — red objects are red elliptical galaxies and blue are star-forming spiral galaxies. The sizes of the blobs indicate the brightness of the galaxies. The complex structure of the large-scale structure of the cosmic web is clearly seen.
Português: Este mapa de uma secção do Universo mostra a posição de milhares de galáxias que foram medidas no âmbito do rastreio VIPERS com o Very Large Telescope do ESO. Um observador na Terra encontra-se à esquerda e quanto mais para a direita, mais longe no tempo estamos a observar as galáxias. Desvios para o vermelho de 0,65 correspondem a olhar para trás no tempo cerca de seis mil milhões de anos e desvios para o vermelho de 1,0 correspondem a cerca de oito mil milhões de anos atrás. As cores indicam as cores verdadeiras das galáxias - objetos vermelhos são galáxias elípticas vermelhas e os azuis são galáxias espirais com formação estelar intensa. Os tamanhos dos pontos indicam o brilho das galáxias. A estrutura complexa da estrutura a larga escala da teia cósmica pode ser vista claramente.
