Artist’s impression of the E-ELT at night

Artist's impression of the European Extremely Large Telescope (E-ELT) at night whilst observations are in progress. The 39-metre E-ELT will be the largest optical/infrared telescope in the world — the world's biggest eye on the sky. Operations are planned to start early in the next decade, and the E-ELT will tackle some of the biggest scientific challenges of our time.

The design for the E-ELT shown here was published in 2009 and is preliminary.
