An aerial image showing, at its centre, a large metallic dome illuminated by the sunset, on top of a mountain that takes up the entire bottom half of the frame. On the background there's a desert mostly obscured with shadows.

An aerial image showing a huge dome from above, partially split into two halves. Along the edges of each half there’s a complex network of metallic beams and catwalks. The opening reveals part of the metallic frame of a huge telescope inside the dome.

Over 70% complete, our ELT is glowing in the #sunset light of the Atacama Desert in #Chile, surrounded by massive cranes hard at work to get this telescope up and running.

With the first light planned for the end of the decade, the ELT and its groundbreaking 39-metre main mirror will take on some of the biggest challenges in #astronomy and, ultimately, help us understand our place in the #Universe.
