On This Day in Space! Oct. 5, 1962: Happy Birthday, European Southern Observatory!

On. Oct. 5, 1962, the European Southern Observatory was born! The European Southern Observatory (ESO) is an intergovernmental research study company made up of 16 nations that work together to study the southern sky. Before ESO, all the major ground-based telescopes worldwide remained in the Northern Hemisphere. ESO built some really big and really amazing telescopesin Chile.
