Atacama Desert - Valle de la Luna

Chile Total Eclipse

Great Chile Total Eclipse & Giant Telescopes

June 22 - July 4, 2019

Nowhere on earth is there a place more suitable for powerful astronomical ground-based observatories than Chile. The dry air of the Atacama Desert and the flat land and high mountains offer the perfect place for building these giant telescopes. Here is the center of the galaxy with the Milky Way so distinct it looks like a gossamer ribbon weaving its way past the Large and Small Magellanic Clouds, the Southern Cross and in 2019 the total eclipse of the Sun.
