A solar eclipse occurs when the moon passes between the Earth and the sun, obscuring part or all of the star from the planet.

It will be the first total solar eclipse that has been visible in the continental U.S.in more than three decades. He added that when the last total solar eclipse raced across the country in 1918, people didn't have numerous technological tools that are at our disposal today.

"It's going to traverse the entire pass of the United States", Kopernik Observatory Executive Director Drew Deskur said.

The mid-valley is right in the path of totality, when the full shadow of the moon completely blocks the sun. Some in the region will even experience a total solar eclipse, resulting in complete darkness around 2:30 p.m. The tech giant has promised to ship some 2 million glasses to 4,800 public libraries across the United States, all in the hopes that as many kids as possible will get to see the moon crossing directly in front of the sun.

Many of you are no doubt gearing up for the solar eclipse on August 21, just two weeks from tonight. Special eclipse glasses can protect your eyes. Retired NASA astrophysicist and photographer Fred Espenak has seen 27 solar eclipses and says although it only lasts for a few minutes, the experience is truly out of this world. Since the path of the shadow appears at varying locations on Earth, people usually have to travel to distant locations to observe totality.

Taking safety precautions, such as a wearing proper eye protection, is important to avoid solar retinopathy, which can lead to mild to moderate vision reduction or even central blind spots, according to a University of Louisville news release. Make sure you have a filter that covers the lens of the telescope, not the eyepiece and is specifically designed for solar viewing.

Darkness will last just under two minutes in OR, gradually expanding to a maximum two minutes and 44 seconds in Shawnee National Forest in southernmost IL, nearly into Kentucky, then dwindling to 2 1/2 minutes in SC. They were offering a program to libraries.
