The European Extremely Large Telescope will become operational



European Southern Observatory :
A revolutionary new telescope is built in Cerro Armazones, Chile, by the European Southern Observatory (ESO), an intergovernmental research organisation supported by fifteen countries. It has the aim of observing the universe in greater detail than even the Hubble Space Telescope.Originally planned for 2018, the observatory is delayed until 2022 due to financial problems. The mirror is also reduced in size slightly, having previously been 42m.
