Alonso (crater)
Alonso is a crater in the southern hemisphere of Miranda, a moon of Uranus, located at 44° S, 352.6 ° E. It has a diameter of . The crater is named after Alonso, King of Naples, one of the characters in Shakespeare's ''The Tempest''. The name Alonso was officially approved by the International Astronomical Union (IAU) in 1988. Geology and characteristics Alonso is roughly 24–25 kilometers in diameter and contains a central mound roughly 14 kilometers in diameter. Many of Miranda's craters and other surface features were covered in a thick layer of surface material known as regolith after formation in a process called mantling. However, Alonso is relatively pristine and exposed, exhibiting minimal mantling. Assuming that the effects of mantling and mass wasting Mass wasting, also known as mass movement, is a general term for the movement of rock (geology), rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

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 ...

He is widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of River Avon, Warwickshire, Avon" or simply "the Bard". 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] |
The Tempest
''The Tempest'' is a Shakespeare's plays, play by William Shakespeare, probably written in 1610–1611, and thought to be one of the last plays that he wrote alone. After the first scene, which takes place on a ship at sea during a tempest, the rest of the story is set on a remote island, where Prospero, a magician, lives with his daughter Miranda (The Tempest), Miranda, and his two servants: Caliban, a savage monster figure, and Ariel (The Tempest), Ariel, an airy spirit. The play contains music and songs that evoke the spirit of enchantment on the island. It explores many themes, including Magic (supernatural), magic, betrayal, revenge, forgiveness and family. In Act IV, a wedding masque serves as a play-within-a-play, and contributes spectacle, allegory, and elevated language. Although ''The Tempest'' is listed in the First Folio as the first of Shakespeare's comedies, it deals with both tragic and comic themes, and modern criticism has created a category of Shakespeare's ...

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 ...

Regolith
Regolith () is a blanket of unconsolidated, loose, heterogeneous superficial deposits covering solid rock. It includes dust, broken rocks, and other related materials and is present on Earth, the Moon, Mars, some asteroids, and other terrestrial planets and moons. Etymology The term '' regolith'' combines two Greek words: (), 'blanket', and (), 'rock'. The American geologist George P. Merrill first defined the term in 1897, writing: Earth Earth's regolith includes the following subdivisions and components: * soil or pedolith * alluvium and other transported cover, including that transported by aeolian, glacial, marine, and gravity flow processes. * "saprolith'", generally divided into the ** ''upper saprolite'': completely oxidised bedrock ** ''lower saprolite'': chemically reduced partially weathered rocks ** ''saprock'': fractured bedrock with weathering restricted to fracture margins * volcanic ash and lava flows that are interbedded with unconsolidated materia ...

Mass Wasting
Mass wasting, also known as mass movement, is a general term for the movement of rock (geology), rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not Entrainment (physical geography), entrained in a moving medium, such as water, wind, or ice. Types of mass wasting include Downhill creep, creep, solifluction, rockfalls, debris flows, and landslides, each with its own characteristic features, and taking place over timescales from seconds to hundreds of years. Mass wasting occurs on both terrestrial and submarine slopes, and has been observed on Earth, Mars, Venus, Jupiter's moon Io (moon), Io, and on many other bodies in the Solar System. Subsidence is sometimes regarded as a form of mass wasting. A distinction is then made between mass wasting by subsidence, which involves little horizontal movement, and mass wasting by slope movement. Rapid mass wasting events, such as landslides, ca ...
