Gemini South

 

Gemini South

Name(s) Gemini South
Status Operational
Broad Science Goals
  • Twin telescopes in both hemispheres provide participant members with access to the entire sky
  • To provide the best image quality possible from the ground for telescopes of their size.
  • To provide the cleanest possible (i.e., lowest possible emissivity) telescopes, for optimal infrared observing from the ground.
The Gemini Observatory is a world-leader in wide-field adaptive optics assisted infrared imaging, and supports research in almost all areas of astronomy.
