Science / Astrology / Eclipse: An occultation, commonly used in reference to a darkening of the Sun or Moon. Solar eclipses occur at the times of those new Moons when the Moon, Sun and Earth are aligned so that the Moon blocks the Sun (totally or partially) from Earth's view. Lunar eclipses occur at certain full Moons during which the Sun, Earth and Moon are so aligned that Earth blocks the Sun's light from the Moon, and the Moon is invisible to earthlings.
Eclipse Verb Synonyms: conceal, hide, blot out, obscure, block, veil, shroud, cover, darken
Eclipse Noun Synonyms: decline, downturn, slump, recession
