Solar Eclipses On The Moon
Solar eclipses on the Moon are caused when the planet Earth passes in front of the Sun and blocks its light. Viewers on Earth experience a lunar eclipse during a solar eclipse on the Moon. These solar eclipses are only seen in the near side portion and smaller parts of the far side where Earth is seen during librations, these areas of the moon making up the visible portion of the Moon. Eclipses there are seen during the lunar sunrise and sunset and extend to the furthermost areas of the near side but mainly not in the polar areas of the Moon. While the Moon orbits Earth, Earth rotates once in nearly 24 hours, but its position at the sky is only in one position, as it never changes. This is in contrast to some other moons or other satellites orbiting other planets or dwarf planets and a few asteroids, even inside the Solar System. They are, however, very rare in the outer part of the Solar System. The last solar eclipse on the Moon was a total eclipse on 8 November 2022, wit ...

Eclipse From Moon
An eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden). The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

MSX Moon
MSX is a standardized home computer architecture, announced by Microsoft and ASCII Corporation on June 16, 1983. It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, then vice-president at Microsoft and director at ASCII Corporation. Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines. MSX systems were popular in Japan and several other countries. Eventually, 9 million MSX units were sold worldwide, including in Japan alone. Despite Microsoft's involvement, few MSX-based machines were released in the United States. The very first commercial MSX for the public was a Mitsubishi ML-8000, released on October 21, 1983, thus marking its official "release date". The meaning of the acronym MSX remains a matter of debate. In 2001, Kazuhiko Nishi recalled t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

SELENE
In ancient Greek mythology and religion, Selene (; grc-gre, Σελήνη , meaning "Moon"''A Greek–English Lexicon's.v. σελήνη) is the goddess and the personification of the Moon. Also known as Mene, she is traditionally the daughter of the Titans Hyperion and Theia, and sister of the sun god Helios and the dawn goddess Eos. She drives her moon chariot across the heavens. Several lovers are attributed to her in various myths, including Zeus, Pan, and the mortal Endymion. In post-classical times, Selene was often identified with Artemis, much as her brother, Helios, was identified with Apollo. Selene and Artemis were also associated with Hecate and all three were regarded as moon and lunar goddesses, but only Selene was regarded as the personification of the Moon itself. Her Roman equivalent is Luna. Names and etymology The name "Selene" is derived from the Greek noun ''selas'' ('), meaning "light, brightness, gleam". In the Doric and Aeolic dialects, her nam ...

Solar Eclipses On Uranus
Solar eclipses on Uranus occur when any of the natural satellites of Uranus passes in front of the Sun as seen from Uranus. Solar eclipse, Eclipses can occur only near a solar ring plane-crossing of Uranus (equinox), occurring approximately every 42 years, with the last crossing being in 2007/2008. For bodies that appear smaller in angular diameter than the Sun, the proper term would be a astronomical transit, transit and bodies that are larger than the apparent size of the Sun, the proper term would be an occultation. Twelve satellites of Uranus—Cressida (moon), Cressida, Desdemona (moon), Desdemona, Juliet (moon), Juliet, Portia (moon), Portia, Rosalind (moon), Rosalind, Belinda (moon), Belinda, Puck (moon), Puck, Miranda (moon), Miranda, Ariel (moon), Ariel, Umbriel (moon), Umbriel, Titania (moon), Titania and Oberon (moon), Oberon—are large enough and near enough to eclipse the Sun. All other satellites of Uranus are too small or too distant to produce an umbra. At its ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Solar Eclipses On Saturn
Solar eclipses on Saturn occur when the natural satellites of Saturn pass in front of the Sun as seen from Saturn. These eclipses happen fairly often. For example, some of Saturn's moons can have a solar eclipse every day depending on the saturnian season. For bodies which appear smaller in angular diameter than the Sun, the proper, more general term would be a transit and for those that are larger than the apparent size of the Sun, the proper term would be an occultation. Seven of Saturn's satellites – Janus, Mimas, Enceladus, Tethys, Rhea, Dione and Titan – are large enough and near enough to eclipse or occult the Sun, or in other words to cast an umbra on Saturn. Most of the more distant satellites, besides being tiny, have orbits that are strongly inclined to the plane of Saturn's orbit, and would rarely be seen to transit. At this distance, the sun covers only about 3 arcminutes in the sky of Saturn. In comparison, the seven major moons of Saturn have angular di ...

Solar Eclipses On Neptune
Solar eclipses on Neptune occur when substantial natural satellites of Neptune pass in front of the Sun as seen from the planet. For bodies which appear smaller in angular diameter than the Sun, the proper term would be a transit and bodies which are larger than the apparent size of the Sun, the proper term would be an occultation. All of Neptune's inner moons and Triton can eclipse the Sun as seen from Neptune. All other satellites of Neptune are too small and/or too distant to produce an umbra. From this distance, the Sun's angular diameter is reduced to one and a quarter arcminutes across. Here are the angular diameters of the moons that are large enough to fully eclipse the Sun: Naiad, 7–13'; Thalassa, 8–14'; Despina, 14–22'; Galatea, 13–18'; Larissa, 10–14'; Proteus, 13–16'; Triton, 26–28'. Just because the moons are large enough to fully eclipse the Sun does not necessarily mean that they will do so. Eclipses of the Sun from Neptune are rare due to the pla ...

Solar Eclipses On Jupiter
Solar eclipses on Jupiter occur when any of the natural satellites of Jupiter pass in front of the Sun as seen from the planet Jupiter. For bodies which appear smaller in angular diameter than the Sun, the proper term would be a transit. For bodies which are larger than the apparent size of the Sun, the proper term would be an occultation. There are five satellites capable of completely occulting the Sun: Amalthea, Io, Europa, Ganymede and Callisto. All of the others are too small or too distant to be able to completely occult the Sun, so can only transit the Sun. Most of the more distant satellites also have orbits that are strongly inclined to the plane of Jupiter's orbit, and would rarely be seen to transit. When the four largest satellites of Jupiter, the Galilean satellites, occult the Sun, a ''shadow transit'' can be seen on the surface of Jupiter which can be observed from Earth in telescopes. Eclipses of the Sun from Jupiter are not particularly rare, since Jupi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Solar Eclipses On Mars
The two moons of Mars, Phobos and Deimos, are much smaller than Earth's Moon, greatly reducing the frequency of solar eclipses on that planet. Neither moon's apparent diameter is large enough to cover the disk of the Sun, and therefore they are annular solar eclipses and can also be considered transits. Eclipses caused by Phobos Due to the small size of Phobos (about ) and its rapid orbital motion, an observer on the surface of Mars would never experience a solar eclipse for longer than about thirty seconds. Phobos also takes only 7 hours 39 minutes to orbit Mars, while a Martian day is 24 hours 37 minutes long, meaning that Phobos can create two eclipses per Martian day. These are annular eclipses, because Phobos is not quite large enough or close enough to Mars to create a total solar eclipse. The highest resolution, highest frame rate video of a Phobos transit has been recently released from the Mastcam-Z on Perseverance rover https://www.jpl.nasa.gov/news/nasas-per ...

Lunar Eclipse
A lunar eclipse occurs when the Moon moves into the Earth's shadow. Such alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, which can happen only on the night of a full moon when the Moon is near either lunar node. The type and length of a lunar eclipse depend on the Moon's proximity to the lunar node. When the moon is totally eclipsed by the Earth, it takes on a reddish color that is caused by the planet when it completely blocks direct sunlight from reaching the Moon surface, as only the light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish due to the Rayleigh scattering of blue light, the same reason sunrise and sunsets are more orange than during the day. Un ...

Langrenus (crater)
Langrenus is an impact crater located near the eastern lunar limb. The feature is circular in shape, but appears oblong due to foreshortening. It lies on the eastern shore of the Mare Fecunditatis. To the south is the overlapping crater pair Vendelinus and the smaller Lamé. The inner wall of Langrenus is wide and irregularly terraced, with an average width of about 20 kilometers. The outer ramparts are irregular and hilly, and there is a bright, fragmented ray system spread across the mare to the west. The interior of the crater has a higher albedo than the surroundings, so the crater appears bright when the Sun is overhead. The crater floor is covered by many boulders, and is slightly irregular in the northwest half. The central peaks rise about a kilometer above the floor, and a peak on the eastern rim ascends to an altitude of 3 km. On December 30, 1992, Audouin Dollfus of the Observatoire de Paris observed a series of glows on the floor of this crater using the one ...

Copernicus (lunar Crater)
Copernicus is a lunar impact crater located in eastern Oceanus Procellarum. It was named after the astronomer Nicolaus Copernicus. It typifies craters that formed during the Copernican period in that it has a prominent ray system. It may have been created by debris from the breakup of the parent body of asteroid 495 Eulalia 800 million years ago. Characteristics Copernicus is visible using binoculars, and is located slightly northwest of the center of the Moon's Earth-facing hemisphere. South of the crater is the Mare Insularum, and to the south-south west is the crater Reinhold. North of Copernicus are the Montes Carpatus, which lie at the south edge of Mare Imbrium. West of Copernicus is a group of dispersed lunar hills. Due to its relative youth, the crater has remained in a relatively pristine shape since it formed. The circular rim has a discernible hexagonal form, with a terraced inner wall and a 30 km wide, sloping rampart that descends nearly a kilometer to the s ...
