Night-time image from the ALMA webcam

ALMA, the Atacama Large Millimeter/submillimeter Array, as seen at night from the newly-installed camera. The Moon is high in the sky illuminating the landscape and the stars are visible everywhere. From its remote home high up on Chile’s Chajnantor Plateau, ALMA observes the Universe in “light” that is invisible to human eyes, and that emanates from some of the coldest objects in space, such as the clouds of dust and gas where stars are just beginning to form. The moonshine on the Chajnantor plateau is so bright that it almost looks like daylight.
