Solar eclipse in Chile

Chile is the astronomy capital of the world, “the world’s eyes to the universe,” and is the ideal destination for observing the solar eclipses in 2019 and 2020.

When the moon passes between the earth and the sun, the different phases of the eclipse can be observed from our planet, showing how the sun is partially or totally hidden.
