Antennae take it easy at ALMA

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. The bright sunshine does not mean that it is toasty warm - ALMA's high altitude makes conditions harsh for humans and other life — but ideal for observations.
