Akutagawa (crater)
Akutagawa is a crater on Mercury. It has a diameter of 106 kilometers. Its name was adopted by the International Astronomical Union (IAU) in on September 25, 2015. Akutagawa is named for the Japanese writer Ryūnosuke Akutagawa. Much of Akutagawa is surrounded by low-reflectance material (LRM), thought to be caused by the carbon mineral graphite Graphite () is a Crystallinity, crystalline allotrope (form) of the element carbon. It consists of many stacked Layered materials, layers of graphene, typically in excess of hundreds of layers. Graphite occurs naturally and is the most stable ....

Shakespeare Quadrangle
The Shakespeare quadrangle is a region of Mercury running from 90 to 180° longitude and 20 to 70° latitude. It is also called Caduceata. The Borealis quadrangle is north of Shakespeare quadrangle. To the west is Raditladi quadrangle, and to the east is Victoria quadrangle. To the southwest is Tolstoj quadrangle, and to the southeast is Beethoven quadrangle. Mariner 10 imaging Prior to the images taken by MESSENGER, the only spacecraft images of Mercury were those taken by the Mariner 10 spacecraft, which made three passes of the planet in 1974–75 (Murray and others, 1974a,b; Strom and others, 1975a). Most images used in mapping the geology of the Shakespeare quadrangle were taken during the near-equatorial first pass, with close encounter or the dark side of the planet. The second, south-polar pass did not image the Shakespeare quadrangle at high resolution. High-resolution images of small areas within the quadrangle were also obtained during the third pass, when th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury (planet)
Mercury is the first planet from the Sun. It is a rocky planet with a trace atmosphere. While it is the List of Solar System objects by size, smallest and least massive planet of the Solar System, its surface gravity is slightly higher than that of Mars. The surface of Mercury is similar to Earth's Moon, heavily Impact crater, cratered, with expansive rupes system, generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of , which is about one-third the diameter of the planet (). Being the most inferior planet, inferior orbiting planet it appears in Earth's sky, always close to the Sun, either as a "morning star" or an "evening star". It stays most of the time the closest to all other planets and is the planet with the highest delta-v needed to travel to from all other planets of the Solar System. Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ryūnosuke Akutagawa
, art name , was a Japanese writer active in the Taishō period in Japan. He is regarded as the "father of the Japanese short story", and Japan's premier literary award, the Akutagawa Prize, is named after him. He took his own life at the age of 35 through an overdose of barbital. Early life Ryūnosuke Akutagawa was born in Irifune, Kyōbashi, Tokyo City (present-day Akashi, Chūō, Tokyo), the eldest son of businessman Toshizō Niihara and his wife Fuku. His family owned a milk production business. His mother experienced mental illness shortly after his birth, so he was adopted and raised by his maternal uncle, Michiaki Akutagawa, from whom he received the Akutagawa family name. He was interested in classical Chinese literature from an early age, as well as in the works of Mori Ōgai and Natsume Sōseki. He entered the First High School in 1910 and developed relationships with classmates such as Kan Kikuchi, Kume Masao, Yūzō Yamamoto, and , all of whom would la ...

International Astronomical Union
The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium 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. the Union had 85 national members and 12,734 individual members, spanning 90 countries and territories. 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 ...

Graphite
Graphite () is a Crystallinity, crystalline allotrope (form) of the element carbon. It consists of many stacked Layered materials, layers of graphene, typically in excess of hundreds of layers. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on a large scale (1.3million metric tons per year in 2022) for uses in many critical industries including refractories (50%), lithium-ion batteries (18%), foundries (10%), and lubricants (5%), among others (17%). Graphite converts to diamond under extremely high pressure and temperature. Graphite's low cost, thermal and chemical inertness and characteristic conductivity of heat and electricity finds numerous applications in high energy and high temperature processes. Types and varieties Graphite can occur naturally or be produced synthetically. Natural graphite is obtained from naturally occurring geologic deposits and synthetic graphite is produced t ...
