The solar eclipse is a phenomenon where the Sun, when observed from the Earth’s surface, is completely or partially blocked out by the Moon. One of the total solar eclipse facts says for the phenomenon to occur, the Moon, the Earth and the Sun must be in a straight line. To clearly observe the total solar eclipse is even rarer since it can be viewed only from a few parts of the world at a time. And even if you are at the right place, observing a total solar eclipse or even a solar eclipse can depend on reasons like weather or clear sky. So if you are lucky you might get to see the first total solar eclipse of 2019 on Tuesday (July 2, 2019).
Next solar eclipse will occur on December 26, 2019. It will be an annular solar eclipse and will be visible from East Europe, North West Australia, Asia including Nepal.

If you are about to view a (total) solar eclipse, always wear tinted sunglasses, else your eyes will be damaged permanently. This exposure to harmful sun rays can cause damage in the cells of your retina or destroy them. It may leave you with a retinal burn also known as retinopathy.
Such exposure can result in total blindness, and it can affect what you see, or the transmission to your brain. It could take a person a few days to realize that their eye(s) has/have been damage after viewing the solar eclipse with the naked eye.
Watching solar eclipse using smartphones or camera should also not be done as you can risk looking directly at the Sun. It can also harm your cameras and their lenses. Solar filters, specifically designed to observe a solar eclipse, should be used as others may not be safe enough.
Use the precautions and you enjoy this year’s first total solar eclipse of 2019, without harming yourself. Enjoy the rare phenomena with your friends and family.
