In preparation for such a rare event, people have been purchasing NASA-approved eclipse glasses to witness the great eclipse on August 21. In previous years, odd occurrences in animals have also been observed such as in the 1500s, when birds were described by an astronomer to have fallen out of the trees and stopped singing during an eclipse.
AAS says its best tip for testing if your glasses are safe is when you put them on, "you shouldn't be able to see anything...except the sun itself".
Those interested in viewing the solar eclipse can attend a public viewing event on Quincy Hill from 12:30 p.m. - 3:30 p.m.
Not wearing them could result in lasting damage called solar maculopathy, or a sunburn to the retina. But one sheriff has some tips in case you're anxious. The longest period of total darkening will be about two minutes and 40 seconds, according to NASA.
Southern Californians won't see the total eclipse - when the sun will be completely blocked by the moon, casting darkness on Earth - only a partial eclipse, explained Shovit Bhari, CSUF staff physicist.
Today, I'd like to get much more detailed and granular about what happens for those lucky enough to be in the path of totality. Utah will finally be in the path of a total solar eclipse-in 2045.
What do I need to see it?
Millions of Americans are getting ready to view the next eclipse on August 21, but Dr. Russell Van Gelder from the University of Washington School of Medicine warns blindness is a risk if you dont have proper eye protection. However, as totality is ending, there's a flash of sunlight when the moon moves off the sun. They answered a variety of questions and stressed the importance of solar eclipse safety.
We don't see a total solar eclipse with every new moon because there are other stipulations, too.
The solar eclipse occurs when the sun, the moon and the Earth forms a straight line.
Stretching from roughly 50 to 400 miles above Earth's surface, the tenuous ionosphere is an electrified layer of the atmosphere that reacts to changes from both the Earth below and space above.
It might seem unusual that the moon is able to cover the sun because it's 400 times smaller.
Fienberg adds that "genuinely" safe solar filters will block at least 99.999% of the Sun's visible and ultraviolet light and at least 97% of the Sun's infrared radiation.
