Progress on European Southern Observatory's (ESO) Extremely Large Telescope (ELT) continues. This gigantic structure will feature a massive 39 metre mirror and will be the largest optical and infrared telescope in the world. In April the ESO and Chilean flags were raised at the top of the telescope’s dome as part of the Topping Out or Roofing Ceremony, celebrating construction on the ELT reaching its highest point.
UK ATC is playing a key role working on five of the planned astronomy instruments for the ELT.
