Atacama High-Altitude Observatory Webcam

Atacama High-Altitude Observatory

The Atacama Large Millimeter/submillimeter Array is a high-altitude observatory officially opened in 2013 after an international collaboration. It is located in northern Chile on the Chajnantor Plateau at about 5,000 meters (16,500 ft) above sea level. The facility is operated by organizations such as the European Southern Observatory and the National Radio Astronomy Observatory. Due to extreme altitude and conditions, the main observatory site is not open to the general public. Visitors can instead access a lower facility near San Pedro de Atacama through limited guided tours. The observatory is used by professional scientists who study space using advanced radio antennas in one of the clearest and driest environments on Earth.

The webcam shows the Observatory, where dozens of giant radio antennas are spread across a high desert plateau. It is presented in 4K quality, giving a very clear view of the sharp mountain landscape and the futuristic-looking dishes. During the day, viewers can see the antennas slowly repositioning as they track astronomical targets across the sky. At night, the scene becomes especially striking, with a deeply dark sky filled with stars, the Milky Way, and almost no light pollution. The combination of ultra-high-altitude desert air and advanced imaging makes it one of the clearest live astronomy webcams in the world.
