Capturando el universo en ultra alta definición
Esta fotografía, tomada desde el Observatorio Paranal de ESO, es la primera fotografía de la Expedición ESO de ultra alta definición (ESO Ultra HD Expedition) — una travesía pionera que están llevando a cabo un cámara de vídeo junto con Fotógrafos embajadores de ESO [1] mundialmente reconocidos. Equipados con herramientas de ultra alta definición de última tecnología [2][3], el equipo está captando, en toda su grandeza, los tres lugares de Chile en los que ESO tiene instaladas sus herramientas de observación, al tiempo que documentan su viaje y sus escapadas en un blog.
En esta imagen vemos, desde una perspectiva inusual, los cuatro Telescopios Unitarios — Antu, Kueyen, Melipal y Yepun —, uno de los Telescopios Auxiliares del VLT (Very Large Telescope) y el telescopio VST (VLT Survey Telescope). Obtenida utilizando una lente de ojo de pez, esta técnica fotográfica produce una imagen de 360° del entorno, sumergiéndonos en un Paranal absorbente, con una Vía Láctea en remolino como imagen central.
Sobre el VLT vemos dispersas algunas joyas cósmicas, manchando de sombras de zafiro el cielo nocturno. Cerca de la parte superior de la imagen, la Luna y Venus, una junto a la otra, brillando radiantes junto con Saturno (justo encima de la cúpula, hacia el extremo de la imagen) a medida que se alinean de un modo hermoso en la línea de la eclíptica. También son visibles Antares, Vega y Altaír, algunas de las estrellas más brillantes del cielo [4]. Refulgiendo débilmente hacia la izquierda, cerca del Telescopio Auxiliar, podemos ver dos galaxias enanas irregulares vecinas de la Vía Láctea, conocidas como la Pequeña y la Gran Nube de Magallanes. Las imágenes “fulldome” en bruto obtenidas con la lente de ojo de pez durante la expedición se distribuirán en breve, sin coste alguno, para su uso en espectáculos de planetario (como las que se crearán a partir del año 2017 para las instalaciones ESO Supernova).
La expedición comenzó en Santiago (Chile) el 25 de marzo de 2014. Al día siguiente, el equipo partió para su primera parada en un observatorio de ESO: el de Paranal, en el que fue tomada esta imagen el 26 de marzo de 2014. Allí permanecerán durante los próximos días grabando planos de “time-lapse”, vídeos y panorámicas de Paranal, hogar de la instalación más representativa de ESO, el Very Large Telescope , para después trasladarse hacia el Observatorio La Silla para fotografiar a ALMA (Atacama Large Millimeter/submillimeter Array) y regresar a Europa el 8 de abril.
