2024 Total Solar Eclipse: A Spectacular Celestial Event
In 2017, millions of people across the United States witnessed a once-in-a-lifetime event: a total solar eclipse that stretched from the Pacific to the Atlantic. Now, just a few years later, another mesmerizing celestial phenomenon is set to captivate the nation. On April 8, 2024, a total solar eclipse will grace the skies once again, but this time with some intriguing differences.
The 2024 total solar eclipse will follow a path that starts in the Pacific and ends in the Atlantic, tracking from southwest to northeast. This is a stark contrast to the 2017 eclipse, which moved from northwest to southeast. The change in direction is just one of the many disparities between these two awe-inspiring events.
One notable difference is the duration of totality. In 2017, the moon’s shadow covered the Earth for a maximum of 2 minutes and 40 seconds. However, in 2024, lucky spectators will be treated to an extended period of darkness, with totality lasting an impressive 4 minutes and 28 seconds. This means that those within the path of totality will have even more time to witness the breathtaking beauty of a fully eclipsed sun.
Another distinction lies in the width of the path of totality. In 2017, the shadow’s path spanned approximately 70 miles, while in 2024, it will expand to around 115 miles. This means that a larger portion of Earth’s surface will be enveloped in darkness during the upcoming eclipse. As a result, many more people will have the opportunity to experience totality firsthand.
The varying distances between Earth, the sun, and the moon play a crucial role in shaping these differences. While the distance from Earth to the sun fluctuates throughout the year, it remains relatively constant during both eclipses. However, the moon’s distance from Earth does change due to its slightly elliptical orbit. During the 2017 eclipse, the moon was approximately 231,155 miles away from Earth. In contrast, during the upcoming eclipse, it will be a mere 223,392 miles away. This seemingly small difference in distance leads to significant variations in the size of the moon’s conical shadow that falls on Earth. Consequently, the path of totality in 2024 will be wider, covering a larger area.
The position of the moon and Earth’s rotation also contribute to the dissimilar paths of the two eclipses. The moon’s orbital path around Earth intersects with the ecliptic, the apparent path of the sun through our daytime sky, at two points known as nodes. Both the 2017 and 2024 eclipses occur at the ascending node, meaning the moon is moving upward during these events. However, the angle of Earth during each eclipse is what truly sets them apart. Earth’s axis is tilted by 23.4 degrees, causing its orientation to change as it rotates throughout the year. This change in orientation results in the apparent movement of North America during the eclipses. In 2017, North America appeared to move up the globe as Earth rotated, while in 2024, it will appear to move down.
Interestingly, the paths of the 2017 and 2024 eclipses intersect, creating an “Eclipse Crossroads” area in parts of southeastern Missouri, southern Illinois, and western Kentucky. This region, spanning approximately 9,000 square miles, will witness a second totality in less than seven years. Makanda, Illinois, located near Carbondale, is at the center of this convergence. Other fortunate locations within this area include Paducah, Kentucky, Cape Girardeau, and Farmington, Missouri. Additionally, Texas Hill Country boasts its own “Eclipse Crossroads” region, covering 14,000 square miles, centered on Vanderpool. This area recently experienced an annular solar eclipse on October 14, 2023, serving as a prelude to the upcoming total eclipse.
One final distinction between the 2017 and 2024 eclipses lies in the sun’s magnetic activity. The sun operates on an 11-year cycle known as the solar cycle, during which its magnetic activity fluctuates. The 2017 eclipse occurred close to the solar minimum, when magnetic activity was low. In contrast, the 2024 eclipse will take place during the predicted solar maximum, offering spectators a chance to witness heightened magnetic activity on the sun’s surface. This means that those wearing solar eclipse glasses during the partial phases of the eclipse may be able to observe sunspots, dark areas of magnetic activity. Additionally, totality will reveal a larger corona, streamers throughout the corona, and prominences, which appear as bright, pink curls or loops emanating from the sun.
