The world's largest → optical and
→ near infrared
telescope, with a diameter of 42 m, to be built by the
→ European Southern Observatory (ESO).
→ First light is foreseen for 2018. The
telescope has an innovative five-mirror design that includes advanced
→ adaptive optics to correct for the
→ atmospheric turbulence, giving
exceptional → image quality. The
→ primary mirror will consist of almost 1000
hexagonal segments each 1.4 m across. The → secondary mirror
will be 6 m in diameter. The E-ELT will collect 15 times
more light than the largest optical telescopes operating today.
