Solar eclipses are dramatic astronomical events where the moon briefly casts its shadow upon Earth. While total solar eclipses are infrequent for any single location, Kentucky is regularly positioned to observe partial eclipses. The focus for sky-watchers now shifts to the next time the moon will pass in front of the sun over the Bluegrass State.
The Next Major Solar Eclipse Visible in Kentucky
The next solar eclipse visible in Kentucky is a Partial Solar Eclipse occurring on Wednesday, August 12, 2026. This event will not feature the dramatic darkening of a total eclipse, but will see the moon take a small crescent-shaped bite out of the sun’s disk. The partial phase will be brief, beginning around 1:40 p.m. EDT and concluding by 1:45 p.m. EDT for many areas in the state.
This minor event is part of a larger total solar eclipse whose path of totality sweeps across the Arctic, Greenland, Iceland, and northern Spain, completely bypassing North America. Since Kentucky is far outside the central shadow, the sun obscured by the moon will be minimal, offering only a slight dimming of the daylight. Observers will need specialized viewing equipment to safely notice the subtle change in the sun’s shape. The last major total solar eclipse to cross Kentucky was the April 8, 2024 event, which saw communities like Paducah and Henderson experience a brief period of total darkness.
Understanding the Path of Totality vs. Partial View
A solar eclipse is classified by the type of shadow cast on the observer’s location. The path of totality is a narrow track, typically less than 100 miles wide, where the moon completely blocks the sun’s bright face. Only observers within this path experience totality, the moment when the solar corona becomes visible and the sky darkens significantly.
A partial solar eclipse occurs when the observer is in the moon’s outer shadow, called the penumbra, and only a portion of the sun is covered. For the upcoming 2026 event, the entire state will only be within the penumbra, meaning the sun will never be fully covered.
Essential Safety Precautions for Viewing
Looking directly at the sun without proper protection can cause severe, permanent eye damage known as solar retinopathy. Safe viewing requires using specialized solar filters that comply with the international safety standard ISO 12312-2. These filters are thousands of times darker than ordinary sunglasses and block damaging ultraviolet and infrared radiation.
Observers must never use regular sunglasses, smoked glass, or exposed film, as these materials do not adequately filter the sun’s harmful invisible rays. Optical devices like cameras, binoculars, or telescopes must only be used if they are fitted with approved solar filters over the front lens. Using an unfiltered optical device while wearing eclipse glasses can concentrate the sun’s rays, instantly burning a hole through the filter and causing serious eye injury.
Looking Ahead: Future Solar Events
For those seeking the full spectacle of a total solar eclipse in the United States, a significant wait follows the 2026 partial event. The next total solar eclipse to cross a wide swath of the contiguous United States will occur on August 12, 2045. This event’s path of totality will stretch from coast to coast, offering many states the full experience. Following the 2045 event, the next total solar eclipse visible from the contiguous U.S. will be on March 30, 2052. These distant dates underscore the rarity of the moon’s shadow perfectly aligning with populated areas.
