English: The full Moon looms large in this Picture of the Week, framing ESO’s Extremely Large Telescope (ELT). Taken at precisely the moment that the rising Moon appears to perch atop Cerro Armazones, this perfectly timed photo captures the striking halo created around the ELT’s ongoing construction.On either side of the telescope’s structure we can see the outlines of gigantic cranes, hard at work shaping what will become the world’s largest optical and infrared telescope. The construction team, led by the company Cimolai, has partially covered the ELT dome with insulating cladding, captured here shining as the sun sets, that will protect the telescope from sunlight and the harsh environment of the Atacama desert. Through an opening in this dome, we can also peek at the telescope’s main structure, which will hold the ELT’s five mirrors. Right now, one of the two sliding doors that will cover this opening is being installed.This stunning image was taken on 13 March by our colleague Juan Beltrán, who works at ESO’s Paranal Observatory, not far from the ELT. And as you can tell from the images linked below, other photographers joined in to capture this unique alignment. As work continues on the ELT, we’re watching it grow before our very eyes — and look forward to sharing more inspiring shots like this one.
