Take a tour of the European Southern Observatory’s stunning research facilities

You’ve likely seen astronomy photos that were taken at one of the European Southern Observatory’s research facilities. But have you ever gotten a good look at some of the jaw-dropping buildings that make those shots possible? If not, you’ll want to pay a visit to In Focus, where Alan Taylor has assembled over 30 photos of the various ESO observatories at La Silla, Paranal, and Llano de Chajnantor. You’ll also find a number of space images taken by the powerful tools housed at these locations. But it’s the photos that show these telescopes in use — a laser beaming into the night sky, a vast array of radio antennas — that strike us as special here.
