New Technology Telescope

The New Technology Telescope is an astronomical observatory in the Atacama Desert at 2,375 meters elevation. Its primary mirror spans 3.58 meters in diameter and uses modern active optics technology to observe the sky.

The telescope was built in 1989 and introduced active optics technology at that time. This innovation allowed the mirror shape to be automatically adjusted to maintain observation quality throughout the night.

The site attracts researchers and students from around the world who work together on observations and discoveries. This collaboration shapes the place and makes it a hub for international astronomical research.

The very dry sky and lack of light pollution create ideal conditions for astronomy. Visitors should prepare for the high elevation and extreme dryness of the region.

The instrument uses especially thin mirror technology, making it significantly lighter than traditional telescopes. An advanced control system regulates all adjustments fully automatically while astronomers conduct their observations.
