The Extremely Large Telescope (ELT), which is currently being built in the Atacama desert in Chile, will be the biggest telescope ever built.Its primary mirror will be 39 metres in diameter, which is slightly less than the size of the Arc de Triomphe in Paris, while it's main structure will weigh 3700 tonnes.Overall, the telescope will use five mirrors to obtain sharp images of the Universe.
One of the key parts of this telescope, which is part of the European Southern Observatory (ESO) is an imager called MICADO (Multi-Adaptive Optics Imaging Camera for Deep Observations).
