Illustrative image: The Atacama Large Millimeter/submillimeter Array ( ALMA ) — a state-of-the-art telescope to study light from some of the coldest objects in the Universe — operates high on the Chajnantor plateau in the Chilean Andes. ALMA comprises 66 high-precision antennae , each weighing in at over 100 tons. Unusual clouds obscure the sky, and a hard frost twinkles from the ground. — S. Otarola /ESO/Wikimedia Commons, CC BY 4.0
