This August, the sun, the moon and planet Earth will all align as Americans witness the country's first total solar eclipse in 38 years.
The Aug. 21 eclipse, dubbed the Great American Eclipse by astronomers, will also mark the first time the phenomenon has occurred from coast-to-coast in nearly 100 years, giving spectators in Oregon, Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, North Carolina, Georgia and South Carolina the chance to get a load of the eclipse in all of its totality.

According to NASA, the center-line path of totality — where the moon completely blocks the sun, the earth goes dark and the sun's corona shimmers in the blackened sky — will stretch from Salem, Oregon, to Charleston, South Carolina, and will last up to 2 minutes and 41.6 seconds.
Spectators outside the center-line path will observe a two- to three-hour partial solar eclipse.
That includes residents in metro Atlanta, which is between 40-80 miles outside the center-line path.
Find out what your sky will look like on Aug. 21 using the Google simulator or Vox eclipse tool, the latter of which will also tell you how far northeast you need to travel to see a total solar eclipse.
To help Georgians prepare for the monumental celestial spectacle expected to attract space junkies from all over the world, we’ve put together some of the best ways you can catch the can’t-miss marvel of the year.
Drive to Georgia’s best eclipse watch spots:
If you want to be within the centerline path of the total solar eclipse in Georgia, which only grazes the northeast corner of the state, your best bet is to make your way to Rabun County, about two hours north of metro Atlanta.
There, the total solar eclipse will begin at 2:35 p.m. and last for 2 minutes and 40 seconds.
Rabun County is also hosting an array of events to commemorate the rare eclipse, the AJC previously reported. Some events include bluegrass at Tallulah Falls, a golf tournament at Sky Valley Country Club, a lecture series with astronomers and a 5K run.
On Aug. 21, spectators can join Georgia State University astronomers in the OutASight Total Solar Eclipse Viewing Party, where jumbotrons linked to NASA will help guide the event.
