50 Years of Incredible Space Images From the European Southern Observatory This week marks the 50th anniversary of one of the world’s leading astronomical institutions, the European Southern Observatory. In honor of ESO’s birthday, we take a look at some of its most stunning shots of the night sky, amazing objects in space, and the organization's beautiful telescope facilities. ESO started when astronomers from five European countries – Belgium, France, Germany, the Netherlands, and Sweden – came together on Oct. 5, 1962 to build a telescope in the Southern Hemisphere. Having a large telescope south of the equator gave these member states access to unprecedented clear skies and celestial objects that simply can’t be seen from the Northern Hemisphere, such as the Magellanic Clouds. Over the decades, many more countries have joined, including Denmark, Switzerland, Italy, Portugal, the United Kingdom, Finland, Spain, the Czech Republic, Austria, and, in 2010, Brazil, which became the first non-European state to join.
