Four antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) gaze up at the star-filled night sky, in anticipation of the work that lies ahead. The Moon lights the scene on the right, while the band of the Milky Way stretches across the upper left. ALMA is being constructed at an altitude of 5000 m on the Chajnantor plateau in the Atacama Desert in Chile. This is one of the driest places on Earth and this dryness, combined with the thin atmosphere at high altitude, offers superb conditions for observing the Universe at millimetre and submillimetre wavelengths. At these long wavelengths, astronomers can probe, for example, molecular clouds, which are dense regions of gas and dust where new stars are born when a cloud collapses under its own gravity. Currently, the Universe remains relatively unexplored at submillimetre wavelengths, so astronomers expect to uncover many new secrets about star formation, as well as the origins of galaxies and planets, when ALMA is operational. The ALMA project is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. This panorama was taken by ESO Photo Ambassador José Francisco Salgado.

Solar Array Clean Low cost power. We see more of these in the future or maybe there will be no future.

En la imagen, el lago Kulunda aparece completamente congelado. No ocurre lo mismo con los otros lagos más pequeños. Estos han de tener una mayor concentración de sales disueltas en sus aguas.
El lago de Kulunda (en ruso: Кулундиское озеро, Kouloundiskoïe ozero) es un amplio lago endorreico de agua ligeramente salina de Rusia, localizado en el extremo sur de la gran llanura de Siberia Occidental, siendo el lago más grande de la estepa de Kulunda, en el krai de Altái. Tiene forma ovalada, con una superficie de 728 km ² (dependiendo del nivel del agua) y un diámetro de unos 25-35 km. La profundidad promedio es de 2,5 a 3 m, con un máximo de 4,5 metros y está a una altitud de 99 m s. n. m. Es ligeramente salado y se encuentra a unos 64 km al este de la ciudad de Slavgorod.

Lake Kulunda or Kulundinskoye (Russian: Кулундинское озеро) is a lake in the southern part of the West Siberian Plain, Altai Krai, south-central Russia.
Lake Kulunda is the largest lake in Altai Krai. It is an endorheic lake located in the eastern side of the Kulunda Plain, near the western limit of the Ob Plateau. This lake, along with many other lakes in the region, exhibits a wide array of colors. (en.wikipedia.org/wiki/Lake_Kulunda)
