English: This 4K visualization shows the Moon's phase and libration at hourly intervals throughout 2024, as viewed from the Northern Hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon's orbit position, sub-Earth and subsolar points, and distance from the Earth at true scale.
The lunar phases and librations in 2019 in the Northern Hemisphere at hourly intervals, with music, titles, and supplemental graphics Simulated views of the Moon over one month, demonstrating librations in latitude and longitude. Also visible are the different phases, and the variation in visual size caused by the variable distance from Earth.
SpaceEngine is an interactive 3D planetarium and astronomy software [2] initially developed by Russian astronomer and programmer Vladimir Romanyuk. [3] Development is now continued by Cosmographic Software, an American company founded by Romanyuk and the SpaceEngine Team in February 2022, based in Connecticut.
The Moon then wanes as it passes through the gibbous moon, third-quarter moon, and crescent moon phases, before returning back to new moon. The terms old moon and new moon are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the Sun and begins to wax ...
Project LOLA. Project LOLA, or Lunar Orbit and Landing Approach, was a simulator built at the NASA's Langley Research Center to study landing on the lunar surface. Built to aid the Apollo astronauts, it aimed to provide a detailed visual encounter with the Moon's landscape, costing nearly $2 million.
Location of Tycho as seen from the Northern Hemisphere 3D model of Tycho crater. Tycho (/ ˈ t aɪ k oʊ /) is a prominent lunar impact crater located in the southern lunar highlands, named after the Danish astronomer Tycho Brahe (1546–1601). [2]
A full moon sinking behind San Gorgonio Mountain, California, on a midsummer morning. Moonrise and moonset are times when the upper limb of the Moon appears above the horizon and disappears below it, respectively. The exact times depend on the lunar phase and declination, as well as the observer's location.
The synodic month, i.e. the mean period for the phases of the Moon. Now called "System B", it reckons the synodic month as 29 days and (sexagesimally) 3,11;0,50 "time degrees", where each time degree is one degree of the apparent motion of the stars, or 4 minutes of time, and the sexagesimal values after the semicolon are fractions of a time ...
