late 13c., from Old French eclipse “eclipse, darkness” (12c.), from Latin eclipsis, from Greek ekleipsis “an abandonment, an eclipse,” from ekleipein “to forsake a usual place, fail to appear, be eclipsed,” from ek “out” (see ex-) + leipein “to leave” (cognate with Latin linquere; see relinquish).
late 14c. (intransitive, a sense now obsolete), from eclipse (n.). Transitive use from late 15c.; figurative use from 1580s. Related: Eclipsed; eclipsing.
The partial or total blocking of light of one celestial object by another. An eclipse of the Sun or Moon occurs when the Earth, Moon, and Sun are aligned. ◇ In a solar eclipse the Moon comes between the Sun and Earth. During a total solar eclipse the disk of the Moon fully covers that of the Sun, and only the Sun’s corona is visible. ◇ An annular eclipse occurs when the Moon is farthest in its orbit from the Earth so that its disk does not fully cover that of the Sun, and part of the Sun’s photosphere is visible as a ring around the Moon. ◇ In a lunar eclipse all or a part of the Moon’s disk enters the umbra of the Earth’s shadow and is no longer illuminated by the Sun. Lunar eclipses occur only during a full moon, when the Moon is directly opposite the Sun.
Our Living Language : The Sun is about 400 times wider than the Moon and 400 times farther from Earth, causing the two to appear to be almost exactly the same size in our sky. This relationship is also responsible for the phenomenon of the total solar eclipse, an eclipse of the Sun in which the disk of the Moon fully covers that of the Sun, blocking the Sun’s light and causing the Moon’s shadow to fall across the Earth. A total solar eclipse can be viewed only from a very narrow area on Earth, or zone of totality, where the dark central shadow of the Moon, or umbra, falls. From this perspective one can view the Sun’s delicate corona—tendrils of charged gases that surround the Sun but are invisible to the unaided eye in normal daylight. This is also the only time when stars are visible in the day sky. Those viewing the eclipse from where the edges of the Moon’s shadow, or penumbra, fall to Earth will see only a partial solar eclipse. The orbits of the Earth around the Sun and of the Moon around the Earth are not perfect circles, causing slight variations in how large the Sun and Moon appear to us and in the length of solar eclipses. The maximum duration of a total solar eclipse when the Earth is farthest from the Sun and the Moon is closest to the Earth is seven and a half minutes.
In astronomy, the blocking out of light from one object by the intervention of another object. The most dramatic eclipses visible from the Earth are eclipses of the sun (when sunlight is blocked by the moon) and eclipses of the moon (when sunlight on its way to the moon is blocked by the Earth).
Note: The term eclipse is also used to refer to a general decline or temporary obscurity: “After taking the title last year, the team has gone into an eclipse this season.”

of the sun alluded to in Amos 8:9; Micah 3:6; Zech. 14:6; Joel 2:10. Eclipses were regarded as tokens of God’s anger (Joel 3:15; Job 9:7). The darkness at the crucifixion has been ascribed to an eclipse (Matt. 27:45); but on the other hand it is argued that the great intensity of darkness caused by an eclipse never lasts for more than six minutes, and this darkness lasted for three hours. Moreover, at the time of the Passover the moon was full, and therefore there could not be an eclipse of the sun, which is caused by an interposition of the moon between the sun and the earth.

- Eclipsing variable star
eclipsing variable star A variable star whose change in luminosity is caused by two or more stars in a binary or multiple system eclipsing each other rather than by any intrinsic property of the star itself. The period of variation coincides with the orbital period of the system and can range from a few minutes […]
