This narrow track is called the path of totality. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar corona to be visible.

Partial and annular phases of the solar eclipse of May 20, 2012 The symbol for an occultation, and especially a solar eclipse, is (U+1F775 🝵). Enthusiasts known as eclipse chasers or umbraphiles travel to remote locations to see solar eclipses. Only the total phase of a total solar eclipse is safe to view without protection. Looking directly at the Sun can lead to permanent eye damage, so special eye protection or indirect viewing techniques are used when viewing a solar eclipse. Astronomers' predictions of eclipses began in China as early as the 4th century BC eclipses hundreds of years into the future may now be predicted with high accuracy. In some ancient and modern cultures, solar eclipses were attributed to supernatural causes or regarded as bad omens. Total eclipses are more rare because they require a more precise alignment between the centers of the Sun and Moon, and because the Moon's apparent size in the sky is sometimes too small to fully cover the Sun.Īn eclipse is a natural phenomenon.

Solar (and lunar) eclipses therefore happen only during eclipse seasons, resulting in at least two, and up to five, solar eclipses each year, no more than two of which can be total. Instead, because the Moon's orbit is tilted at about 5 degrees to Earth's orbit, its shadow usually misses Earth. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. In partial and annular eclipses, only part of the Sun is obscured. In a total eclipse, the disk of the Sun is fully obscured by the Moon. Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. During a partial solar eclipse (right), the Moon blocks only part of the Sun's disk ( October 25, 2022).Ī solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, totally or partially.
