DescriptionArecibo naic big.gif	Česky: Radioteleskop v Arecibu. English: The 1000 ft. (305 m) diameter Arecibo radio telescope is the largest single-dish telescope in the world. The spherical dish is too large to move. Pointing is accomplished by the rotation of the earth. A 40-degree wide band of the sky parallel to the celestial equator is visible to the telescope. This photo appears to be one that was taken to document the 1974 upgrading of the aluminium dish. Français : Le radiotélescope d'Arecibo est le plus grand téléscope simple jamais construit (diamètre de 305 mètres). L'antenne, sphérique, est beaucoup trop large pour bouger ; le pointage se fait ainsi grâce à la rotation de la Terre. La zone observable du ciel par le téléscope est comparable à une bande de 40° de hauteur parallèle à l' équateur céleste.

Wikipedia for Schools brings Wikipedia into the classroom. SOS Childrens Villages believes education is an important part of a child's life. That's why we ensure they receive nursery care as well as high-quality primary and secondary education. When they leave school, we support the children in our care as they progress to vocational training or higher education. Will you help another child today?
