Researchers at the European Southern Observatory headquarters in the town of Garching,near Munich,are working on developing innovative new telescopes. One of them is the E-ELT,or the European Extremely Large Telescope.
This model shows what could one day be the world's biggest telescope. Its main mirror will measure 42 meters in diameter. It's been designed for the European Southern Observatory. The Extremely Large Telescope - or ELT as this kind of telescope is called - will give astronomers an unprecedented look at space.
