October - Night view of the ELT under construction on Cerro Armazones

This image shows a webcam view of the construction site of ESO’s Extremely Large Telescope at Cerro Armazones, in Chile’s Atacama Desert. At the time the photograph was taken, in June 2023, engineers and construction workers were assembling the structure of the telescope dome.

The starry background is dominated by the core of the Milky Way, our home galaxy, and the Large and Small Magellanic clouds, two dwarf galaxies that orbit our own.
