Most Recent Total Solar Eclipse in the United States
The last total solar eclipse in the United States occurred on April 8, 2024. This event crossed a narrow path from Mexico through 13 U.S. states and into Canada, with totality lasting up to about 4 minutes in some locations. A total solar eclipse happens when the Moon completely covers the Sun, turning day into darkness for a brief period. The next total solar eclipse visible in the United States will occur on August 23, 2044. Before 2024, the previous U.S. total eclipse was on August 21, 2017.
Understanding Solar Eclipses
A solar eclipse occurs when the Moon passes between the Sun and Earth, blocking some or all of the Sun’s light. There are three main types: total, partial, and annular. A total solar eclipse takes place when the Moon fully obscures the Sun’s disk, revealing the Sun’s outer atmosphere, or corona. A partial solar eclipse occurs when only a portion of the Sun is covered, and an annular eclipse happens when the Moon is too far from Earth to completely cover the Sun, leaving a ‘ring of fire’ of visible sunlight. Eclipses are predictable because they follow repeating cycles in the geometry of the Earth, Moon, and Sun.

Path of Totality
The path of totality for the April 8, 2024 eclipse crossed North America diagonally. It entered the United States in Texas and moved northeast through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Tennessee, Michigan, Ohio, Pennsylvania, and New York, before crossing into Canada and ending in Atlantic Canada. Locations within this narrow corridor experienced up to several minutes of total darkness in the middle of the day. Outside this path, viewers saw a partial eclipse, with the Moon covering only part of the Sun.

How Often Eclipses Occur in the United States
On average, a total solar eclipse occurs somewhere on Earth about every 18 months. However, any given location on Earth may see a total eclipse only once every few centuries, because the path of totality is narrow. In the United States, total solar eclipses in the 21st century have been relatively rare. The next total solar eclipse after 2024 visible in the United States will not occur until 2044. Between now and then, other parts of the United States will experience annular or partial eclipses, but not a total eclipse.
Partial and Annular Eclipses in the United States
In addition to total eclipses, the United States has also experienced partial and annular eclipses in recent years. A partial solar eclipse occurs when the Moon covers only a part of the Sun, and an annular eclipse occurs when the Moon is at or near its farthest point from Earth, appearing smaller and leaving a ring of sunlight visible. While these events are striking, they differ from a total eclipse because the Sun’s bright disk remains partially visible. Upcoming eclipse types visible in the United States include annular eclipses and additional partial eclipses before the next total event in 2044.
What to Know About the 2024 Eclipse
The April 8, 2024 total solar eclipse provided a widely observed celestial event across much of North America. During totality, viewers within the path of darkness saw stars and planets become briefly visible in the daytime sky, and animals often reacted as if it were dusk. Outside the path of totality, people in the remainder of the United States saw a partial eclipse, with varying degrees of coverage. Safe viewing using eclipse glasses or indirect projection methods was recommended for all partial phases. The 2024 eclipse was notable for its clear weather prospects in many regions and strong public interest in eclipse viewing events.
Looking Ahead
Eclipse cycles are predictable and follow patterns that scientists have modeled for centuries. When the next total solar eclipse occurs on August 23, 2044, it will cross a path from the Pacific Northwest through the central United States into Canada. Marking calendars now can help observers plan ahead, whether for travel, education, or photography. Clear skies are never guaranteed, but advance preparation increases the chances of experiencing these rare events safely and fully.
