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.
