The steel skeleton of the world's largest visible- and infrared-light telescope is illuminated by the rising full moon in a new photo from the European Southern Observatory (ESO).
Construction of ESO's Extremely Large Telescope (ELT) is underway on Cerro Armazones in Chile's Atacama Desert, with the monster telescope expected to see its "first light" by 2028. ESO recently shared a spooky new photo of the telescope's progress in honor of Halloween.
