We’re less than a year away from the next great solar eclipse.

The Great North American Solar Eclipse is April 8, 2024. The eclipse will plunge a 124-mile wide swatch of land from Mexico to Canada into darkness. On that day, the moon will move between the sun and the Earth, causing its shadow to move across the Earth’s surface and making the sun appear dark.

The last major solar eclipse in the U.S. was in 2017. The 2024 total solar eclipse will last longer and cast a wider shadow than the 2017 one, meaning it will be more easily viewed by more people, Space.com said. The 2024 eclipse will cross the path of the 2017 one near Carbondale, Illinois.

The Great North American Total Solar Eclipse of 2024 will start in Mazatlán, Mexico, at 10:51 a.m. local time. It will then move northeast across the continent through Newfoundland and Labrador in Canada where the eclipse will begin at 4:07 p.m. local time. You can go here to see a map of the eclipse path.

Totality for the eclipse – the moment when the moon fully covers the sun and the sky goes dark – will last up to 4 minutes, 26 seconds. You can go here to see NASA’s tips for safely viewing the eclipse.

A partial eclipse will be visible from the majority of the states in the continental U.S. but the path of totality – and the best viewing – will cross Texas, Oklahoma, Arkansas, Missouri, Kentucky, Illinois, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine. For the best viewing, make sure you’re located within the path of totality.
