A fascinating new heatmap from NASA showcases the patterns of total solar eclipses over a span of 5,000 years, from 2000 BCE to 3000 CE. This detailed visualization includes options to view without a color key and without outlines of continents.
Have you ever wondered how frequently solar eclipses grace our skies? According to NASA’s innovative heatmap, a specific spot on Earth witnesses a total solar eclipse about once every 366 years on average.
This brings us to the extraordinary event set for April 8, in regions of southern Illinois, Missouri, and Kentucky. A vast area of approximately 32,400 square miles will be plunged into darkness for 4 minutes and 9 seconds. This comes just six years, months, and 18 days after these locations enjoyed a 2 minutes and 38 seconds display during the last “Great American Eclipse.”
Towns like Perryville and Cape Girardeau in Missouri, Paducah in Kentucky, and several others in Illinois, including Carbondale and Marion, are on the brink of witnessing this rare celestial phenomenon.
NASA’s map, the centerpiece of this article, traces the paths of 3,742 total and hybrid solar eclipses across 5,000 years. This comprehensive compilation was made possible through the Five Millennium Canon of Solar Eclipses, a project by Fred Espenak and Jean Meeus published in 2006.
The map reveals that every pixel experiences at least one total solar eclipse, averaging 13.66 eclipses over the 5,000-year period. This equates to an average gap of 366 years between eclipses at any given location, a figure that intriguingly sits between previous estimates by astronomers.
Ernie Wright of NASA’s Scientific Visualization Studio has uncovered some fascinating insights regarding the distribution and frequency of total solar eclipses globally:
– Every location on the map will see between one and 35 total solar eclipses over 5,000 years.
– The northern hemisphere is more prone to experiencing total solar eclipses, a result of Earth’s slightly elliptical orbit.
– Total solar eclipses are more common in the summer months, largely due to the longer daylight hours.
Despite the rarity of witnessing a total solar eclipse twice in one’s lifetime in the same place, our planet regularly hosts these celestial events. Earth sees between two and five solar eclipses annually, with total eclipses sometimes just 354 days apart. However, the average interval for total solar eclipses globally is about 18 months.
