ELT (Extreme Large Telescope, see for more info) is the world’s largest telescope under construction (39 m diameter) and it is considered worldwide to be one of the highest priorities in ground based astronomy.  ELT will  lead to a greater advancement of astrophysical knowledge, allow a deeper exploration of our Universe, and give sharper views of cosmic objects than ever before.

MAORY, as first generation ELT instrument, will help compensate for the distorsion of light caused by turbolence in the Earth’s atmosphere which make astronomical images blurry  (Adaptive Optics, see  here for more information on Adaptive Optics).
