Enwonwu (crater)
Enwonwu is an impact crater on the planet Mercury. It is named in honor of Ben Enwonwu Odinigwe Benedict Chukwukadibia Enwonwu MBE (14 July 1917 – 5 February 1994), better known as Ben Enwonwu, was a Nigerian painter and sculptor. Arguably the most influential African artist of the 20th century, his pioneering career opened th ..., the modernist Nigerian sculptor and painter. The crater displays a central peak and a set of bright rays emanating from the crater rim. The rays cross the surrounding surface and neighboring craters, indicating that Enwonwu crater was formed comparatively recently in Mercury's history. The brightness of the rays also suggests relative youth, as over time rays darken and disappear on Mercury's surface.

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] |
Ben Enwonwu
Odinigwe Benedict Chukwukadibia Enwonwu MBE (14 July 1917 – 5 February 1994), better known as Ben Enwonwu, was a Nigerian painter and sculptor. Arguably the most influential African artist of the 20th century, his pioneering career opened the way for the postcolonial proliferation and increased visibility of modern African art. He was one of the first African artists to win critical acclaim, having exhibited in august exhibition spaces in Europe and the United States and listed in international directories of contemporary art. Since 1950, Enwonwu was celebrated as "Africa's Greatest Artist" by the international media and his fame was used to enlist support for Black Nationalists movement all over the world. The Enwonwu crater on the planet Mercury is named in his honour. Biography Early life Ben Enwonwu was born a twin on 14 July 1917 into the noble family of Umueze-Aroli in Onitsha, Nigeria. His father, Omenka Odigwe Emeka Enwonwu, was a technician who worked with the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

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] |
Modernism
Modernism is both a philosophy, philosophical and arts movement that arose from broad transformations in Western world, Western society during the late 19th and early 20th centuries. The movement reflected a desire for the creation of new forms of art, philosophy, and social organization which reflected the newly emerging industrial society, industrial world, including features such as urbanization, architecture, new technologies, and war. Artists attempted to depart from traditional forms of art, which they considered outdated or obsolete. The poet Ezra Pound's 1934 injunction to "Make it New" was the touchstone of the movement's approach. Modernist innovations included abstract art, the stream-of-consciousness novel, montage (filmmaking), montage cinema, atonal and twelve-tone music, divisionist painting and modern architecture. Modernism explicitly rejected the ideology of Realism (arts), realism and made use of the works of the past by the employment of reprise, incorpor ...
