Capturando o Universo em Ultra Alta Definição
Esta imagem obtida no Observatório do Paranal do ESO é a primeira fotografia da Expedição Ultra HD do ESO - uma viagem pioneira que está neste momento a ser levada a cabo por quatro vídeo-fotógrafos e Embaixadores Fotográficos do ESO de renome internacional [1]. Equipados com dispositivos Ultra HD de vanguarda [2] [3], estes profissionais estão a obter imagens dos três locais de observação do ESO no Chile em todo o seu esplendor, ao mesmo tempo que documentam a viagem num blog dedicado.
Podemos ver nesta invulgar imagem os quatro Telescópios Principais do VLT (Antu, Kueyen, Melipal e Yepun), um dos Telescópios Auxiliares da mesma infraestrutura e o Telescópio de Rastreio do VLT (VST). Usando uma lente olho de peixe, obtém-se esta vista de 360º do local - recriando o mundo do Paranal com a Via Láctea ao centro.
Jóias cósmicas distantes encontram-se espalhadas por cima do VLT, salpicando os tons azul safira do céu noturno. Próximo do cimo da imagem, vemos a Lua e Vénus lado a lado, brilhando intensamente com Saturno (que se encontra mesmo por cima da cúpula situada no fundo da imagem), alinhando-se perfeitamente ao longo da eclíptica. Estão também visíveis Antares, Vega e Altair, algumas das estrelas mais brilhantes do céu [4]. Duas galáxias anãs irregulares vizinhas da Via Láctea, a Pequena e a Grande Nuvens de Magalhães, podem ser vistas brilhando fracamente à esquerda, próximo do Telescópio Auxiliar. Toda este material, obtido através da lente olho de peixe durante a expedição, será brevemente distribuído de forma gratuita para ser utilizado em espetáculos de planetário (tais como os que serão apresentados no futuro centro Supernova ESO a partir de 2017).
A expedição começou em Santiago do Chile a 25 de março de 2014. No dia seguinte a equipa partiu para o primeiro observatório do itinerário - o Observatório do Paranal do ESO, onde esta imagem foi obtida a 26 de março de 2014. A equipa permanecerá neste local durante os próximos dias capturando fotografias, vídeos e panoramas do Paranal - local que acolhe a infraestrutura emblemática do ESO, o Very Large Telescope - antes de partir em direção ao Atacama Large Millimeter/submillimeter Array (ALMA), seguindo depois para o Observatório de La Silla e voltando à Europa a 8 de abril.
