ALMA Observatory Radio Telescopes & Starry Sky

The World's Largest Radio Telescope Array

This live stream overlooks the Atacama Large Millimeter/submillimeter Array, a collection of high-precision antennas spread across a remote Andean plateau. Together these dishes work as a single giant telescope, peering through the dust of deep space to study the birth of stars, galaxies and planetary systems.

Skies Like Nowhere Else

At roughly 5,000 metres above sea level, the Chajnantor plateau offers some of the driest, most transparent air on the planet. The result is a breathtaking canvas of stars and the glowing band of the Milky Way, making this one of astronomy's most coveted observing sites.

A Window on the Atacama Desert

The surrounding landscape is pure high desert: barren ridgelines, volcanic peaks and an endless horizon untouched by city light. The stark, silent terrain underlines just how isolated and pristine this corner of northern Chile truly is.

Live Around the Clock

Tune in to this real-time view of cutting-edge science set against one of the most otherworldly environments anywhere on Earth. It is a rare chance to watch the antennas at work beneath the spectacular star-filled skies of the Atacama.
