Know your eclipse lingo: A solar eclipse explainer

The sun at this time appears to have a dark shadow on only a small portion of it.

Using the high-definition images captured during the total solar eclipse, scientists will study the corona for a phenomenon called Alfvén waves, which can occur in a plasma (a gas in which electrons have been separated from their parent atoms) in a magnetic field.

On August 21, a much-anticipated total solar eclipse will cross the United States, from OR to SC.

The eclipse will leave the country entirely in Charleston, South Carolina, at 2:48 p.m.

Note: NASA says the only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as "eclipse glasses" or hand-held solar viewers.

But the moon is slowly moving away from Earth by about 1-1/2 inches (4 centimeters) per year, according to the NASA statement. From our perspective, the moon will cross in front of the sun for several minutes during the middle of the day on Monday, August 21. In 2014, California became the first state to generate at least 5 percent of its electricity from "utility-scale" solar plants - generators producing at least 1 megawatt of capacity, the U.S. Energy Information Administration reports.

The next time a total eclipse will be seen in Georgia will be August 12 2045.

"You have to be on the sunny side of the planet, and you have to be in the path of the moon's shadow", NASA officials said in the video.

To help ensure that you're in the right spot at the right time, NASA provided an interactive map for each of the 11 states that the eclipse will be passing through, and the space agency includes the essential detail of time.
