October — Spot the engineers on the Extremely Large Telescope (ELT)

Do you want to feel small? Check out this image of our Extremely Large Telescope (ELT), and see if you can spot the tiny engineers stood on the massive cell that will hold the ELT's 39 m mirror. 

The mirror will comprise 798 hexagonal segments working together with nanometric accuracy thanks to sophisticated sensors and actuators. It will be the largest segmented mirror ever built, and it will help us unlock some of the deepest secrets of the Universe.
