Countdown begins: Exactly 1 year until the century's longest total solar eclipse turns day into night across three continents

The countdown has begun for one of the most extraordinary celestial events of the century. Exactly one year from today, on August 2, 2027, millions of people across Europe, Africa, and the Middle East are expected to witness what astronomers are already calling the "eclipse of the century."

The total solar eclipse, which will sweep across southern Spain, North Africa, and the Middle East, will be the longest total solar eclipse visible from land this century.

Longest total solar eclipse visible from land this century

The eclipse's path of totality will stretch across southern Spain, Gibraltar, Morocco, Algeria, Tunisia, Libya, Egypt, Saudi Arabia, Yemen, and Somalia. According to Timeanddate.com, around 89 million people live directly within the path of totality, with millions more expected to travel there to witness the event.

At its maximum, totality will last 6 minutes and 22 seconds near Luxor, Egypt, making it the longest total solar eclipse visible from land since 1991 and the longest expected until 2114.

As the moon completely covers the sun, observers within the path of totality will briefly experience daytime turning into darkness while the sun's outer atmosphere, the corona, becomes visible to the naked eye.

Why the 2027 eclipse will last unusually long

The eclipse's extraordinary duration is the result of a rare alignment of celestial mechanics. During the event, the moon will be near perigee, the point in its orbit where it is closest to Earth, making it appear slightly larger than usual. At the same time, Earth will be close to aphelion, when it is farthest from the sun, causing the sun to appear marginally smaller. The eclipse track will also pass close to Earth's equator, where the planet rotates faster, observers to remain inside the moon's shadow for a longer period.

Most total solar eclipses last only two to three minutes. By comparison, more than six minutes of totality will give skywatchers extra time to witness the dramatic transformation of the sky.

Luxor expected to become the eclipse's focal point

Luxor is expected to emerge as one of the world's most sought-after viewing destinations because it combines the eclipse's longest period of totality with one of the most reliable chances of clear August skies.

The ancient Egyptian city, once known as Thebes, offers more than six minutes of darkness alongside some of the world's best-preserved temples and monuments.

Southern Spain offers Europe's easiest viewing opportunity

For many European travelers, southern Spain is expected to be one of the most accessible destinations on the path of totality. Cities including Cádiz, Tarifa, Málaga, and Gibraltar will all experience totality, although the duration will be shorter than in North Africa. Tarifa and Gibraltar are expected to receive more than four minutes of darkness, Cádiz nearly three minutes, and Málaga just under two minutes.

2026 eclipse will serve as a preview

Before the 2027 spectacle arrives, another total solar eclipse will occur on Wednesday, August 12, 2026. The eclipse will be visible along a narrow path crossing eastern Greenland, western Iceland and northern Spain, while a partial eclipse will be visible from Alaska, eastern Canada, 26 U.S. states and most of Europe. Later the same day, skywatchers will also be able to witness the annual peak of the Perseid meteor shower.
