ALMA in the snow

This image shows some of the antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) surrounded by snow. ALMA is a state-of-the-art telescope that is used to study light from some of the coldest objects in the Universe. The antennas sit at 5100 metres above sea level in the Chilean Andes — on a site that is very cold, extremely dry, and not very hospitable for humans!
