Summary

DescriptionALMA and a Starry Night.jpg	English: A crystal-clear sky on any night is always a joy to behold. But if you are on the Chajnantor Plateau, at 5000 metres altitude in the Chilean Andes and one of the best places in the world for astronomical observations, it could be an experience that you’ll remember for your whole life. This panoramic view of Chajnantor shows the antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) against a breathtaking starry night sky. In the foreground, we can see some of ALMA’s antennas, working together. The plateau appears curved, because of the effect of the wide-angle lens used. ALMA is the world’s most powerful telescope for studying the Universe at submillimetre and millimetre wavelengths. Construction work for ALMA will be completed in 2013, and a total of 66 of these high-precision antennas will be operating on the site. At the moment, the telescope is in its initial phase of Early Science Observations. Even though it is not fully constructed, the telescope is already producing outstanding results, outperforming all other submillimetre arrays. In the sky above the antennas, countless stars shine like distant jewels. Two other familiar celestial objects also stand out. First, the image is crowned by the Moon. Second, outshone by the glow of the Moon, it is possible to distinguish the Milky Way as a hazy stripe across the sky. Dark regions within the band are areas where the light from background stars is blocked by interstellar dust. This photograph was taken by ESO Photo Ambassador, Babak Tafreshi. Babak is founder and leader of The World At Night, an international project to produce and exhibit a collection of stunning photographs and time-lapse videos of the world’s landmarks with a backdrop of the most beautiful celestial wonders. ALMA, an international astronomy facility, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ). The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA. Español: Un cielo nocturno claro y cristalino es siempre un placer para la vista. Pero si se encuentra en el Llano de Chajnantor, a 5.000 metros de altitud en los Andes chilenos, (uno de los mejores sitios del mundo para la observación astronómica) puede ser una experiencia que recordará el resto de su vida. Esta vista panorámica de Chajnantor muestra las antenas de ALMA (Atacama Large Millimeter/submillimeter Array) en contraste con el sobrecogedor escenario de fondo: un cielo nocturno plagado de estrellas. Detrás vemos algunas de las antenas de ALMA, trabajando en equipo. El llano aparece curvado debido al efecto de la lente gran angular utilizada. ALMA es el telescopio más potente del mundo para el estudio del universo en longitudes de onda milimétricas y submilimétricas. Las obras de construcción de ALMA se completarán en 2013, y un total de 66 antenas de gran precisión trabajarán en este lugar. Por el momento, el telescopio está en su fase inicial de operaciones, haciendo observaciones científicas tempranas. Pese a que aún no está totalmente construido, el telescopio ya está ofreciendo sorprendentes resultados, superando a las demás instalaciones submilimétricas. En el cielo que puede verse tras las antenas, incontables estrellas brillan como distantes gemas. También destacan dos objetos celestes muy familiares. Primero, la imagen está coronada por la Luna. Segundo, eclipsada por el brillo de la Luna, es posible distinguir la Vía Láctea como una banda brumosa que atraviesa el cielo. Las regiones oscuras dentro de esta banda son áreas en las cuales el polvo interestelar bloquea la luz de las estrellas de fondo. Esta fotografía fue obtenida por el Fotógrafo embajador de ESO, Babak Tafreshi. Babak es el fundador y líder de “The World At Night”, un proyecto internacional para producir y exhibir una colección de fotografías y vídeos time-lapse impactantes de los lugares del mundo con las maravillas celestes más hermosas como telón de fondo. 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
