Always remember watching the sun without taking appropriate precautions may cause serious eye injuries that can even lead to permanent loss of vision.

Next 2nd July a Total Solar Eclipse will happen. The beginning of the eclipse will be in eastern New Zealand in the Pacific Ocean and it will move to Chile and Argentina. The eclipse will be seen as partial from most of South America.

A solar eclipse occurs when the Moon passes between the Earth and Sun and the Moon's shadow crosses the Earth. From the Earth, the Moon and the Sun have almost the same diameter. Moreover, due to the distance variations between the Moon and the Earth, Moon can be seen from the Earth bigger or smaller than the Sun. This gives as a result the three types of eclipses: total, partial or annular.

A total eclipse like that of July takes place when the Moon is on the near side of its orbit appearing larger than the Sun, and is completely aligned between the Earth and the Sun. During a total solar eclipse, we can make observations that are usually impossible without special instruments due to the brightness of the Sun, where you can see the " Baily's beads", some bright spots that come from the last few rays of sunlight shining through valleys on the edge of the Moon, the protuberances of the chromosphere or the solar corona.

This is the second solar eclipse of this year, a partial one could be observed the past 6th January and you will be able to see an annular eclipse from Saudi Arabia, India, Sumatra and Borneo (partial from Asia and Australia) on 26th December

The last total solar eclipse we could see was on August 21, 2017 from N. America, n S. America.
