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 wisps. The next total solar eclipse will occur on July 2, 2019, and the 2019 solar eclipse path will cross through Chile and Argentina.

Much of the rest of South America will view a partial eclipse.

When is the next solar eclipse going to happen?

The eclipse begins on July 2, 2019, at 16:55:13 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 18:01:08 UT.

Where's the best place to watch the 2019 solar eclipse?

The best location on land to watch the total eclipse will be along the eclipse path that crosses through the middle of Chile and Argentina. This total eclipse is of an average length, with a maximum duration of 4 minutes and 32.8 seconds, and it will be low to the horizon (near sunset). The maximum duration will occur over the South Pacific Ocean, and the majority of the eclipse path will fall over the South Pacific Ocean.

When's the next solar eclipse?

The next total solar eclipse will occur on December 14, 2020, and will occur largely over water. Some viewers on land in southern Chile and Argentina will spot totality. Find more information at NASA's eclipse site.
