On Monday, April 8, 2024, a total solar eclipse came to North America.
All of North America and Central America experienced a partial solar eclipse but only those within the path of totality — an approximately 115-mile (185-kilometer) wide route through Mexico, 15 U.S. States and Canada — were able to see the moon entirely cover the sun's disk, according to NASA.
If you missed the celestial event we have rounded up some of the best photos from our readers here in our total solar eclipse 2024 gallery.

It came less than six months after the Oct. 14, 2023, 'ring of fire' annular solar eclipse in eight states in the U.S. Southwest as well as Mexico, Guatemala, Belize, Honduras, Nicaragua, Costa Rica, Panama, Colombia and Brazil.
During a total solar eclipse, the moon appears almost exactly the same size as the sun, so it blocks the entire disk for a few minutes. The result is a beautiful totality during which the sun's corona is visible to the naked eye. Here's everything you need to know about this rare event.

This Eclipse Simulator widget below from skywatching app maker SkySafari allowed you to track the moon's shadow on Earth, see how it may look from different locations and follow the event as it unfolds. It does require your location in order to work properly.
What is a total solar eclipse?
A solar eclipse occurs when a new moon is positioned precisely between Earth and the sun and casts its shadow on Earth. It happens when the moon appears the same size in the sky as the sun, or slightly larger, so fully covers the disk of the sun, giving observers a view of the sun's outer atmosphere, the corona.
The apparent size of the moon in the sky — and whether it can completely cover the sun's disk during an eclipse — depends on the moon's distance from Earth. The moon has a slightly elliptical orbit around Earth, so at two points each month, it is farthest (apogee) and closest (perigee) to Earth, making the moon appear slightly smaller and slightly larger than average in our sky.
On April 8, 2024, the new moon looked relatively large and, therefore, covered 100% of the sun's disk as viewed from the narrow path of totality that stretched from Sinaloa, Mexico through the U.S. to Newfoundland, Canada. The magnitude of a solar eclipse is the fraction of the diameter of the sun covered by the moon, which on April 8, 2024, was 1.0566, according to EclipseWise.com.
Where was the total solar eclipse?

On April 8, 2024, all of North America and Central America experienced a solar eclipse. For most of that region, the spectacle was solely a partial solar eclipse, though of varying obscuration.
Only within the path of totality, which is 100 to 123 miles (162 to 200 kilometers) wide, was a totally eclipsed sun be visible. That path stretched from the Pacific Ocean to the Atlantic Ocean. It first made landfall in Mazatlán in Sinaloa, Mexico and crossed Durango and Coahuila. Entering the U.S. at Texas, the path of totality then moved through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Tennessee, Michigan, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine. Ontario, Quebec, New Brunswick, Prince Edward Island and Newfoundland in Canada also experienced totality.
As the path traveled northeast the maximum duration of totality lessened because the moon's distance to Earth changes. At Mexico's Pacific coast, 4 minutes 27 seconds of totality was possible. As the moon's shadow gets larger, the point of longest totality — where viewers could see an eclipsed sun for 4 minutes 28 seconds — occurred at Nazas near Durango, Mexico. After that point the moon's shadow lengthens and narrows, reducing to a maximum totality of 2 minutes 52 seconds as the path exited North America at Newfoundland.

Where and when was the total solar eclipse visible?
Here are some notable locations and cities that experienced a total solar eclipse, together with the local time and duration of that event, according to Jubier. Note that all of these places also saw a long partial solar eclipse before and after the brief totality; their closeness to the centerline of the path of totality determines how long totality lasts:
Why was the 2024 total solar eclipse so special?
The 2024 total solar eclipse was a major event. Totality could last twice as long as in 2017, depending on the observer's location. It was also the longest totality on land for over a decade, so eclipse-chasers from around the world flocked to the path of totality.
As a bonus, the sun's corona during totality was huge. That's because the sun is close to solar maximum — when it's most active during its 11 years (or so) solar cycle.
During totality, two planets were visible. Venus was very bright and shone 15º from the sun even before totality began while dimmer Jupiter, 30º from the sun, appeared during totality.
As with all eclipses, it's important to be close to the center of the path of the moon's shadow if you want to experience as long a spectacle as possible. In practical terms that means avoiding the edges of the path of totality, where its length drastically reduces. Aiming for close to the centerline is wise, but there's no need to obsess about it. Besides, a clear sky remains the most important thing.
For those after geographic oddities, the 2017 and 2024 paths crosssed in southern Illinois, Missouri and Kentucky, with locations such as Makanda, Carbondale and Cape Girardeau experiencing totality for the second time in seven years. For a small area of the Texas Hill Country (Uvalde, Concan, Vanderpool, Bandera and Kerrville) it was possible to see both a 'ring of fire' annular solar eclipse on Oct. 14, 2023, and totality on April 8, 2024.
Where was the partial solar eclipse visible?
Totality got most of the attention and all serious eclipse-chasers will try to get to the path of totality. However, on April 8, 2024, most of North and Central America experienced a big partial solar eclipse.
Here is what the biggest cities in Mexico, U.S. and Canada experienced that day at the peak of the event; only Dallas and Montreal (close to St Lawrence River) experienced totality while San Antonio got a 99.9% partial solar eclipse.

Given that huge metropolitan areas in the U.S. northeast — New York, Boston, Philadelphia, Washington D.C., Chicago and St. Louis — were all within a two or three-hour drive of totality, this eclipse was a huge travel event.
St Louis, Memphis, Louisville, Cincinnati, Columbus, Detroit, Toronto, Ottawa and Quebec City were also just outside the path of totality, so lots of day-trippers from these cities traveled to the path of totality.
How to safely view the partial and total solar eclipse
To safely view all of this event, and any future solar eclipses, you must use solar filters. Only those in the path of totality could briefly remove them to see the sun's corona with their naked eyes. Those not in the path of totality must have kept them on the entire time.
Everyone who observed the partial phases of this eclipse — and for those outside the path of totality, that's the entire event — needed to wear solar eclipse glasses while cameras, telescopes and binoculars needed solar filters placed in front of their lenses.
Our how to observe the sun safely guide tells you everything you need to know about safe solar observations.
After April 2024, when is the next total solar eclipse?
After the total solar eclipse on April 8, 2024, the next total solar eclipse will occur on Aug. 12, 2026, when totality will be visible from Greenland, Iceland, the Atlantic Ocean and Spain. At the point of greatest eclipse close to Iceland, totality will last 2 minutes, 18 seconds. According to Eclipsophile, there's a high chance of clouds near Greenland and Iceland, with the best chance of a clear sky in Spain, where totality will occur very low in the sky just before sunset.
For North America, the next total solar eclipses are:
- March 30, 2033: in Alaska.
- Aug. 23, 2044: in Canada and the U.S. (Montana, South Dakota, North Dakota).
- Aug.12, 2045: U.S. (California, Nevada, Utah, Colorado, New Mexico, Oklahoma, Kansas, Texas, Arkansas, Missouri, Mississippi, Louisiana, Alabama, Georgia, Florida), Caribbean and South America.
