New Delhi: Sometime in the year 2014, American space agency NASA had confirmed the occurrence of a total solar eclipse in 2017.
On Monday, August 21, many Americans will be able to witness the phenomenon right from their porches.
NASA recommends that people who plan to view the eclipse should check the safety authenticity of viewing glasses to ensure they meet basic proper safety viewing standards.
Besides that, they can also ensure that the eclipse viewing glasses and handheld solar viewers should meet all the following criteria:
If you want to avoid eclipse viewing glasses and handheld solar viewers for some reason or don't have either option, you can always go for an alternative method for safe viewing of the partially-eclipsed Sun, which is a pinhole projector.
With this method, sunlight streams through a small hole – such as a pencil hole in a piece of paper, or even the space between your fingers – onto a makeshift screen, such as a piece of paper or the ground. It’s important to only watch the screen, not the Sun. Never look at the Sun through the pinhole – it is not safe.
