What is a total solar eclipse?
A total solar eclipse occurs when the Moon covers the face of the Sun as seen from Earth. The complete coverage allows us to see the day as if it were night, and it reveals the solar corona's ghostly whisps. The next total solar eclipse will occur on August 21, 2017, and the 2017 solar eclipse path will cross the continental United States.
North American viewers off the eclipse path will still see a partial solar eclipse.
When is the next solar eclipse going to happen?
The eclipse begins on August 21, 2017, at 16:48:33 Universal Time (UT), when the shadow touches down on the Pacific Ocean and the Moon takes its first small bite out of the Sun. Totality begins at 18:24:11.9 UT.
