The European Extremely Large Telescope (E-ELT) will be a ground-based optical/infra-red telescope with a 42m diameter mirror larger than all the current ground-based telescopes combined. This huge mirror will be built from 984 hexagonal segments. It will use Adaptive Optics to compensate for blurring of images caused by the Earths atmosphere, capturing images up to 10 times sharper than the Hubble Space Telescope. The giant telescope will allow us to study Earth-like planets orbiting stars outside our solar system.
