This spectacular timelapse shows the sun rising behind ESO’s Extremely Large Telescope. It was taken by ESO engineer Eduardo Garcés on 12 April 2025 from Cerro Paranal, home to ESO’s Very Large Telescope and located some 23 km away from Cerro Armazones, where the ELT is located. A similar timelapse was taken in 2023 by ESO astronomer Boris Häußler; comparing the two videos shows how much the construction of the ELT has progressed in less than two years.
