What is a solar eclipse?

Any celestial object like a moon or a planet that passes between two other bodies can create an eclipse by obscuring the view of objects like the sun.

A total eclipse occurs when the moon appears as the same size as the sun and blocks the entire disk from Earth, leading to a period of darkness lasting several minutes. The resulting "totality," whereby observers can see the outmost layer of the sun's atmosphere known as the corona, confuses animals – causing nocturnal creatures to stir and bird and insects to fall silent.

When and where to see the April 8 total solar eclipse

On April 8, the potentially once-in-a-lifetime total solar eclipse will chart a 115-mile-wide path of totality across portions of Mexico the United States and Canada.

In the U.S. alone, hundreds of cities and smaller towns in 13 states lie along the path. An estimated 31 million Americans already live on the path, while millions more tourists are already making travel plans – sure to snarl traffic – to catch a glimpse of what is sure to be a spectacular sight, according to eclipse cartographer Michael Zeiler at GreatAmericanEclipse.com.

Mexico's Pacific coast will be the first location in continental North America to experience totality, which will occur at about 11:07 a.m. PDT, according to NASA.

As the moon's shadow travels northeast, totality in the U.S. will begin at 1:27 p.m. CDT in Eagle Pass, Texas. From there, the path will cut diagonally across the country before ending it's time in the U.S. around 3:33 p.m. EDT in Lee, Maine and entering Canada's maritime provinces, according to nationaleclipse.com.

Along the way, periods of darkness could last a mere few seconds or, in some cities, could surpass four minutes. And as if the dazzling solar eclipse won't be enough, there's a small chance that the horned "devil comet" may make an appearance that same day as it makes its closest orbital approach to Earth later in the month.

Why is this year's total solar eclipse special?

The last time North Americans witnessed a total solar eclipse in 2017, the sun's activity was at a minimum.

This time around, though, the sun will be at the peak activity of an 11-year solar cycle, making its elusive corona especially visible, astronomers say.

Meanwhile, the moon will be closer to Earth than it was seven years ago, making it appear larger in the sky and increasing the length that darkness will last in many places, according to eclipse2024.org.
