ESO's Extremely Large Telescope: Reaching New Construction Milestones
The European Southern Observatory's Extremely Large Telescope (ESO's ELT) has reached the halfway mark in its construction, making it the world's largest telescope for visible and infrared light. Despite challenges posed by the pandemic, progress has been swift, with completion of the second half of the project expected to be significantly quicker. The telescope is set to begin scientific operations in 2028 and will tackle astronomical questions such as the existence of extraterrestrial life and the formation of the universe.
