The Extremely Large Telescope: A Giant Leap for Astronomy

The Atacama Desert in Chile, one of the darkest places on Earth, is hosting the construction of the Extremely Large Telescope (ELT). With a primary mirror 39 meters in diameter—nearly four times larger than existing telescopes—the ELT promises a revolutionary leap in astronomical observation. Competing projects, such as the Giant Magellan Telescope and the Thirty Meter Telescope (currently stalled due to local opposition), aim for similar breakthroughs within the decade. These next-generation telescopes will dramatically alter our view of the cosmos, unveiling previously unseen wonders.
