Why South Pole?

Print edition : May 02, 2014

The South Pole is the chosen site to avoid all kinds of contamination from dust and moisture. The South Pole has the driest environment on the planet. It also has very stable weather patterns and winter temperatures averaging -58˚C. With its clear sky and an effective altitude of about 3,000 metres, the South Pole is the closest a ground-based telescope can get to being in space.
