Verona Rupes
Verona Rupes is the tallest known cliff on Miranda, a moon of Uranus, and plausibly holds the record for the highest cliff in the Solar System. It was discovered by the ''Voyager 2'' space probe in January 1986. Its name was adopted by the International Astronomical Union (IAU) in 1988, named after the city of Verona, which is the setting for ''Romeo and Juliet,'' written by William Shakespeare. It may have been created by a major impact that caused the moon to disrupt and reassemble, or by the crust rifting. Given Miranda's low gravity, it would take about 12 minutes to fall from the top, reaching the bottom at a speed of about 200 km/h. There are many estimates about the cliff's height. It was thought its height was between high, while another places it at a higher altitude of , potentially making it the tallest known cliff in the Solar System. One study estimated that the "true" height of Verona Rupes is around when not accounting for oblique viewing caused by parallax, g ...

Voyager 2
''Voyager 2'' is a space probe launched by NASA on August 20, 1977, as a part of the Voyager program. It was launched on a trajectory towards the gas giants (Jupiter and Saturn) and enabled further encounters with the ice giants (Uranus and Neptune). The only spacecraft to have visited either of the ice giant planets, it was the List of artificial objects leaving the Solar System, third of five spacecraft to achieve Solar escape velocity, which allowed it to leave the Solar System#Farthest regions, Solar System. Launched 16 days before its twin ''Voyager 1'', the primary mission of the spacecraft was to study the outer planets and its extended mission is to study interstellar space beyond the Sun's heliosphere. ''Voyager 2'' successfully fulfilled its primary mission of visiting the Exploration of Jupiter, Jovian system in 1979, the Exploration of Saturn, Saturnian system in 1981, Exploration of Uranus, Uranian system in 1986, and the Exploration of Neptune, Neptunian system ...

Miranda (moon)
Miranda, also designated Uranus V, is the smallest and innermost of Uranus's five round natural satellite, satellites. It was discovered by Gerard Kuiper on 16 February 1948 at McDonald Observatory in Texas, and named after Miranda (The Tempest), Miranda from William Shakespeare's play ''The Tempest''. Like the other large moons of Uranus, Miranda orbits close to its planet's equatorial plane. Because Uranus orbits the Sun on its side, Miranda's orbit is nearly perpendicular to the ecliptic and shares Uranus's extreme seasonal cycle. At just in diameter, Miranda is one of the smallest closely observed objects in the Solar System that might be in hydrostatic equilibrium (spherical under its own gravity), and its total surface area is roughly equal to that of the U.S. state of Texas. The only close-up images of Miranda are from the ''Voyager 2'' probe, which made observations of Miranda during its Uranus flyby in January 1986. During the flyby, Miranda's southern hemisphere po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Romeo And Juliet
''The Tragedy of Romeo and Juliet'', often shortened to ''Romeo and Juliet'', is a Shakespearean tragedy, tragedy written by William Shakespeare about the romance between two young Italians from feuding families. It was among Shakespeare's most popular plays during his lifetime and, along with ''Hamlet'', is one of his most frequently performed. Today, the Title character, title characters are regarded as Archetype, archetypal young lovers. ''Romeo and Juliet'' belongs to a tradition of tragic Romance (love), romances stretching back to Ancient history, antiquity. The plot is based on an Italian tale written by Matteo Bandello, translated into verse as ''The Tragical History of Romeus and Juliet'' by Arthur Brooke (poet), Arthur Brooke in 1562, and retold in prose in ''Palace of Pleasure'' by William Painter (author), William Painter in 1567. Shakespeare borrowed heavily from both but expanded the plot by developing a number of supporting characters, in particular Mercutio a ...

Cliff
In geography and geology, a cliff or rock face is an area of Rock (geology), rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and Dolomite (rock), dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may ...

Uranus
Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. Most of the planet is made of water, ammonia, and methane in a Supercritical fluid, supercritical phase of matter, which astronomy calls "ice" or Volatile (astrogeology), volatiles. Atmosphere of Uranus, The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature () of all the Solar System's planets. It has a marked axial tilt of 82.23° with a Retrograde and prograde motion, retrograde rotation period of 17 hours and 14 minutes. This means that in an 84-Earth-year orbital period around the Sun, its poles get around 42 years of continuous sunlight, followed by 42 years of continuous darkness. Uranus has the third-largest diameter and fourth-largest mass among the Solar System's planets. Based on current models, inside its volatile Mantle (geology), mantle layer is a rocky core, and surrounding it is a thick hydrogen and helium atmosphere. Trace amount ...

His extant works, including William Shakespeare's collaborations, collaborations, consist of some Shakespeare's plays, 39 plays, Shakespeare's sonnets, 154 sonnets, three long narrative poems and a few other verses, some of uncertain authorship. His plays List of translations of works by William Shakespeare, have been translated into every major modern language, living language and are performed more often than those of any other playwright. Shakespeare remains arguably the most influential writer in the English language, and his works continue to be studied and reinterpreted. Shakespeare was born and raised in Stratford-upon-Avon, Warwickshire. At the age of 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallax
Parallax is a displacement or difference in the apparent position of an object viewed along two different sightline, lines of sight and is measured by the angle or half-angle of inclination between those two lines. Due to perspective (graphical), foreshortening, nearby objects show a larger parallax than farther objects, so parallax can be used to determine distances. To measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax. Here, the term ''Stellar parallax, parallax'' is the semi-angle of inclination between two sight-lines to the star, as observed when Earth is on opposite sides of the Sun in its orbit. These distances form the lowest rung of what is called "the cosmic distance ladder", the first in a succession of methods by which astronomers determine the distances to celestial objects, serving as a basis for other distance measurements in astronomy forming the higher rungs of the ladder. Because parallax ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminator (solar)
A terminator or twilight zone is a moving line that divides the daylight, daylit side and the dark night side of a astronomical object, planetary body. The terminator is defined as the locus (mathematics), locus of points on a planet or natural satellite, moon where the line through the center of its parent star is tangent. An observer on the terminator of such an orbiting body with an atmosphere would experience twilight due to light scattering by particles in the gaseous layer. Earth's terminator On Earth, the terminator is a circle with a diameter that is approximately that of Earth. The terminator passes through any point on Earth's surface twice a day, at sunrise and at sunset, apart from polar regions where this only occurs when the point is not experiencing midnight sun or polar night. The circle separates the portion of Earth experiencing daylight from that experiencing darkness (night). While a little over one half of Earth is illuminated at any point in time (with exce ...
