La soledad de ALMA
Esta vista panorámica del Llano de Chajnantor muestra la ubicación del conjunto ALMA (el Atacama Large Millimeter/submillimeter Array), tomada cerca del pico de Cerro Chico. Babak Tafreshi, un Fotógrafo embajador de ESO, ha conseguido captar el sentimiento de soledad que se experimenta en este sitio, a 5.000 metros sobre el nivel del mar en los Andes chilenos. Las luces y las sombras pintan el paisaje, enfatizando el aspecto de este terreno, casi de otro mundo. Al fondo de la imagen, el cúmulo de antenas de ALMA parece una extraña multitud de visitantes robóticos en el llano. Cuando el telescopio se complete en el año 2013, el conjunto estará formado por un total de 66 antenas que operarán juntas.
ALMA ya está revolucionando la forma en que los astrónomos estudian el universo en longitudes de onda milimétricas y submilimétricas. Incluso con solo una parte de las antenas, ALMA es más potente que ningún telescopio previo en esas longitudes de onda, lo que proporciona a los astrónomos una capacidad sin precedentes para estudiar el universo frío — gas molecular y polvo, así como la radiación del Big Bang, una reliquia de esos primeros momentos del universo. ALMA estudia los ladrillos básicos de las estrellas, sistemas planetarios, galaxias, y de la propia vida. Proporcionando a los científicos imágenes detalladas de estrellas y del nacimiento de planetas en nubes de gas cerca del Sistema Solar, y detectando galaxias distantes formándose en los límites del universo observable (con lo cual las vemos como eran aproximadamente hace diez mil millones de años) los astrónomos podrán responder algunas de las preguntas más profundas sobre nuestros orígenes cósmicos.
El Atacama Large Millimeter/submillimeter Array (ALMA), una instalación astronómica internacional, es una colaboración entre Europa, América del Norte y Asia Oriental en cooperación con la República de Chile. La construcción y operaciones de ALMA en Europa están lideradas por ESO; en América del Norte por el National Radio Astronomy Observatory (NRAO); y en Asia Oriental por el Observatorio Astronómico Nacional de Japón (NAOJ). El Joint ALMA Observatory (JAO) proporciona al proyecto la unificación tanto del liderazgo como de la gestión de la construcción, puesta a punto y operación de ALMA.
