ESO's Post

Astronomers focus on the sky, but it’s worth looking around our planet, too! This image, for instance, was taken from Pukará de Quitor, a fortress built 900+ years ago by the Licán Antai community, also known as Atacameños, not far from the Atacama Large Millimeter/submillimeter Array. What a perfect frame for the Licancabur #volcano!
