Breathtaking Dark Sky of ALMA   -  By: Babak A. Tafreshi

From altitude of over 5,000 meters, the night sky view from Chajnantor Plateau in the Chilean Andes is breathtaking. The dark site's rarefied atmosphere, at about 50 percent sea level pressure, is also extremely dry. That makes it ideal for the Atacama Large Millimeter/submillimeter Array (ALMA). With total of 66 giant radio dishes, each 12 or 7 meters in diameter, ALMA will revolutionize exploration of the universe in radio wavelength. ALMA is known as the world's largest ground-based astronomy project now involving many countries. Our neighboring galaxies the Large and Small Magellanic Clouds appear near the south celestial point in this view. See a timelapse video of this scene.
