Mark your calendars! On April 8, 2024, Sky-watchers in North America will be treated to a spectacular sight – a total solar eclipse. Nicknamed the “Great North American Eclipse” by some, this celestial event will be the first total eclipse visible in the contiguous United States since 2017.
What is a Total Solar Eclipse?
A total solar eclipse occurs when the Moon completely covers the Sun, plunging the day into darkness for a brief period. This happens because the Moon’s apparent size is larger than the Sun’s for a short time, blocking all direct sunlight.
Where will the Eclipse Be Visible?
The path of totality, the narrow track where the total eclipse will be seen, will stretch from Mexico through the United States and into Canada. The eclipse will begin over the Pacific Ocean and make landfall on Mexico’s Pacific coast around 11:07 AM PDT.
It will then travel northeast across the United States, passing through states like Texas, Oklahoma, Missouri, Illinois, and Kentucky, before reaching the East Coast. Totality will end in Canada’s Newfoundland province at around 5:16 PM NDT.
Even if you’re not directly in the path of totality, a partial eclipse will still be visible across most of North America. However, to witness the awe-inspiring phenomenon of a total eclipse, it’s important to plan your trip to a location along the path.

Safety First!
Solar eclipses are fascinating events, but it’s crucial to view them safely. Looking straight at the Sun, even if there is a partial eclipse, can result severe eye damage. Special solar eclipse glasses are the only safe way to view the eclipse directly. Ensure that your glasses fit with the international safety standard.
Planning Your Eclipse Experience?
If you’re interested in witnessing the total eclipse, NASA has a helpful website with maps of the path of totality and resources for planning your trip. With careful planning and the proper safety precautions, the Great North American Eclipse promises to be an unforgettable experience.
What happens during a total solar eclipse?
A total solar eclipse is a dramatic event that occurs when the moon passes directly between the sun and Earth, completely blocking the sun’s light in a narrow path across Earth’s surface. Here’s a breakdown of what happens:
Alignment and Shadow:
The moon’s orbit isn’t perfectly aligned with Earth’s orbit around the sun. But occasionally, the moon casts a dark shadow that falls directly onto Earth.
This shadow has two parts: the umbra (inner, dark part) and the penumbra (lighter, outer part).
Stages of the Eclipse:
As the moon starts to move in front of the sun, a partial eclipse begins. The sun appears to have a crescent shape taken out of it.
The sky starts to dim when the moon covers more and more of the sun. Animals may become confused, and temperatures can drop slightly.
Totality occurs when the umbra falls on your location. The sun is completely blocked, and the sky darkens dramatically, as if it were dusk or dawn.
Totality and the Corona:
During totality, which only lasts for a few minutes, you can see the sun’s corona, the faint outer atmosphere, which is normally hidden by the sun’s bright light.
You might also see phenomenon like Baily’s beads (bright points appearing along the moon’s edge) or the diamond ring effect (a bright ring formed by the sun’s corona).
End of the Eclipse:
After totality, the moon gradually moves away from the sun, revealing more and more of its surface. The sky brightens, and the eclipse goes through the partial phase again before ending entirely.
Cultural and historical beliefs around total solar eclipses
Throughout history, total solar eclipses have been a source of wonder and fascination, leading to a variety of cultural and historical beliefs. Here are some common themes:
Monsters Devouring the Sun
Many cultures depict a celestial creature devouring the sun during an eclipse. In China, it was a dragon, while Norse mythology blamed the wolf Skoll. These stories reflected the fear and awe people felt at the sudden disappearance of daylight.
Omens and Portents
Eclipses were often seen as disruptions of the natural order, triggering anxieties. The Babylonians viewed them as warnings about the king, while some cultures interpreted them as signs of coming misfortune or divine anger.
Appeasing the Gods
Fearing the eclipse’s meaning, various cultures attempted to appease their deities. The Chinese would bang drums and make noise to scare away the sun-eating dragon. In some cases, rituals were performed to restore balance and bring back the sun.
Predicting the Future
The ability to predict eclipses, like the Babylonians and Maya, was a mark of great knowledge. These predictions, though not always perfect, helped establish astronomy as a field of study.
Curiosity and Observation
Not all beliefs were negative. Eclipses also sparked curiosity about the heavens. They provided opportunities to observe the sun’s corona, invisible under normal conditions, and fueled the development of early astronomy.
These beliefs highlight the human desire to understand and explain the natural world. While science now provides a clear explanation for eclipses, these cultural interpretations offer a window into how people throughout history grappled with awe-inspiring phenomena.
How often does a total solar eclipse happen?
Total solar eclipses are rare, and ones that are visible from the United States are even rarer. While these events occur somewhere on Earth every one to three years, they are often only visible from Earth’s poles or vast stretches of ocean. Even with clear skies, only those within the specific path of totality will experience the awe-inspiring sight of the sun being completely blocked out by the moon. For those outside this path, a partial eclipse, where the moon covers part of the sun, can still be observed. Source: How often do total solar eclipses happen?
When is the next total solar eclipse?
Skywatchers looking to catch a glimpse of a total solar eclipse within the next decade have a few opportunities!
- The next total eclipse will be visible from Greenland, Iceland, and Spain on August 12, 2026.
- Those in northern Africa, Gibraltar, and the Saudi peninsula can witness a total eclipse on August 2, 2027.
For viewers in the United States:
- A total eclipse will be visible from Alaska in 2033.
- A coast-to-coast total eclipse will occur across the US in 2044, preceded by a total eclipse visible from western Canada, Montana, and North Dakota in 2044.
However, these awe-inspiring events won’t last forever! As the universe expands and the moon drifts slowly away from Earth, while the sun gradually grows larger, the moon will eventually become too small to completely cover the sun during an eclipse. This day is millions of years in the future, though. A NASA study estimates this won’t happen in about 600 million years, so plenty of time for future generations to enjoy the spectacle of a total solar eclipse!
