A lunar phase or Moon phase is the apparent shape of the Moon's directly sunlit portion as viewed from the Earth. Because the Moon is tidally locked with the Earth, the same hemisphere is always facing the Earth.
A lunisolar calendar was found at Warren Field in Scotland and has been dated to c. 8000 BC, during the Mesolithic period. [2] [3] Some scholars argue for lunar calendars still earlier—Rappenglück in the marks on a c. 17,000 year-old cave painting at Lascaux and Marshack in the marks on a c. 27,000 year-old bone baton—but their findings remain controversial.
In lunar calendars, a lunar month is the time between two successive syzygies of the same type: new moons or full moons. The precise definition varies, especially for the beginning of the month. Animation of the Moon as it cycles through its phases, as seen from the Northern Hemisphere. The apparent wobbling of the Moon is known as libration.
At the minor lunar standstill, the Moon will change its declination during the tropical month from +18.3° to −18.3°, for a total range of 37°. Then 9.3 years later, during the major lunar standstill, the Moon will change its declination during the month roughly from +28.6° to −28.6°, which totals 57° in range.
The lunar nodes are the two points where the Moon's orbital path crosses the ecliptic, the Sun's apparent yearly path on the celestial sphere.. A lunar node is either of the two orbital nodes of the Moon; that is, the two points at which the orbit of the Moon intersects the ecliptic.
A total lunar eclipse occurred on 1 March 1504, visible at sunset for the Americas, and later over night over Europe and Africa, and near sunrise over Asia.. During his fourth and last voyage, Christopher Columbus induced the inhabitants of Jamaica to continue provisioning him and his hungry men, successfully intimidating them by correctly predicting a total lunar eclipse for 1 March 1504 ...
A total lunar eclipse will occur at the Moon’s descending node of orbit on Friday, March 14, 2025, [1] with an umbral magnitude of 1.1804. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow.
A total lunar eclipse occurred at the Moon’s descending node of orbit on Friday, July 27, 2018, [1] with an umbral magnitude of 1.6100. It was a central lunar eclipse, in which part of the Moon passed through the center of the Earth's shadow. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened ...
