Handel (crater)
Handel is a crater on Mercury. It has a diameter of 166 kilometers. Its name was adopted by the International Astronomical Union in 1976. Handel is named for the British-German composer George Frideric Handel, who lived from 1685 to 1759. Handel is one of 110 peak ring basins on Mercury.Chapman, C. R., Baker, D. M. H., Barnouin, O.

MESSENGER
''MESSENGER'' was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. The name is a backronym for "Mercury Surface, Space Environment, Geochemistry, and Ranging", and a reference to the messenger god Mercury from Roman mythology. ''MESSENGER'' was launched aboard a Delta II rocket in August 2004. Its path involved a complex series of flybys – the spacecraft flew by Earth once, Venus twice, and Mercury itself three times, allowing it to decelerate relative to Mercury using minimal fuel. During its first flyby of Mercury in January 2008, ''MESSENGER'' became the second mission, after Mariner 10 in 1975, to reach Mercury. ''MESSENGER'' entered orbit around Mercury on March 18, 2011, becoming the first spacecraft to do so. It successfully completed its primary mission in 2012. Following two mission extensions, the spacecraft used the last of its maneuvering propellant to deo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Frideric Handel
George Frideric (or Frederick) Handel (; baptised , ; 23 February 1685 – 14 April 1759) was a German-British Baroque music, Baroque composer well known for his opera#Baroque era, operas, oratorios, anthems, concerto grosso, concerti grossi, and organ concertos. Handel received his training in Halle (Saale), Halle and worked as a composer in Hamburg and Italy before settling in London in 1712, where he spent the bulk of his career and Handel's Naturalisation Act 1727, became a naturalised British subject in 1727. He was strongly influenced both by the middle-German polyphony, polyphonic choral tradition and by composers of the Italian Baroque. In turn, Handel's music forms one of the peaks of the "high baroque" style, bringing Italian opera to its highest development, creating the genres of English oratorio and organ concerto, and introducing a new style into English church music. He is consistently recognized as one of the greatest composers of his age. Handel started three c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Peak Ring
A peak ring crater is a type of complex crater, which is different from a multi-ringed basin or central-peak crater. A central peak is not seen; instead, a roughly circular ring or plateau, possibly discontinuous, surrounds the crater's center, with the crater rim still farther out from the center. Formation The rings form by different processes, and inner rings may not be formed by the same processes as outer rings.Geology Pagewww.geologypage.com/2016/10/research-helps-explain-formation-ringed-crater-moon.html accessdate: February 5, 2017 It has long been the view that peak rings are formed in the stage subsequent to central peak formation in craters. The central peaks of craters are believed to originate from hydrodynamic flow of material lifted by inward-collapsing crater walls, while impact-shattered rock debris is briefly turned to fluid by strong vibrations that develop during crater formation. The peak-ring structure of Chicxulub crater was probably formed as inward-coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominici (crater)
Dominici is a Impact crater, crater on Mercury (planet), Mercury. Dominici's bright rays indicate that it is relatively young, and the young rays appear light blue in enhanced-color images. Dominici also has bright material on its floor and is surrounded by crater ejecta and material that appears orange in enhanced color. These color differences, as in nearby Titian (crater), Titian crater, suggest that the impact crater excavated material from beneath Mercury's surface that differs in composition from the surrounding surface. Dominici lies within a much larger impact structure, the Homer (crater), Homer basin. Bright areas in and around Dominici are Hollows (Mercury), hollows. Mariner 10 image 0027359.png, Mariner 10 image of Homer with Dominici near top Dominici sidebyside2.jpg, Homer basin is marked with a white circle in the enhanced-color image.

Homer (crater)
Homer is a crater on Mercury. It is one of 110 peak ring basins on Mercury. Deposits of material in and around this crater suggest the possibility of explosive volcanic eruptions at some point in the planet's history. An unnamed crater in northwestern Homer (about 18 km diameter) contains hollows and has dark ejecta. The crater name was approved by the IAU in 1976. The naming of Stark Y crater on the moon, located northwest of Stark, as ''Homer'', was not approved by the IAU. The small but fresh crater Dominici lies along the northern margin of Homer. The crater Handel is to the northeast, and Titian is to the southwest. Mariner 10 image 0027359.png, Mariner 10 image of Homer Dominici sidebyside2.jpg, Homer basin is marked with a white circle in the enhanced-color image.

Yeats (crater)
Yeats is an impact crater on the planet Mercury. The crater is named after William Butler Yeats, an Irish poet and dramatist. The name was adopted by the International Astronomical Union in 1976.''NASA World Wind'' 1.4. NASA Ames Research Center, 2007. The rim of Yeats is circular and intact, except where an indentation is made by a crater on the north side. It is bordered by a smaller, unnamed crater to the northwest. There is a scarp cutting across the crater which trends northeast. The central peak is complex, and there are hollows on the east and west sides of the peak. Yeats is located south of the crater Li Po and southwest of the crater Sinan Sinan (Arabic: سنان ''sinān'') is a name found in Arabic and Pre-Islamic Arabic inscriptions, Early Arabic, meaning ''spearhead''.
