Boznańska (crater)
Boznańska is a crater on Mercury (planet), Mercury. Its name was adopted by the International Astronomical Union (IAU) on September 25, 2015. Boznańska is named for the Polish painter Olga Boznańska. Boznańska contains Hollows (Mercury), hollows, located on or close to the central peak complex, as well as on the upper walls of small craters at the center and on the eastern floor.Blewett, D.

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] |
Victoria Quadrangle
The Victoria quadrangle is a region on Mercury from 0 to 90° longitude and 20 to 70 ° latitude. It is designated the "H-2" quadrangle, and is also known as Aurora after a large albedo feature. Most of the Victoria quadrangle lies within an area that appears bright on telescopic images of the planet, the bright-albedo feature Aurora, which approximately coincides with the east half of the quadrangle. As is common with most of the imaged portions of Mercury, the Victoria quadrangle is dominated by basins and large craters, with plains materials occupying the areas between them. The Borealis quadrangle is north of Victoria quadrangle. To the west is Shakespeare quadrangle, and to the east is Hokusai quadrangle. To the south is Kuiper quadrangle, and to the southwest is Beethoven quadrangle. ''Mariner 10'' images Almost all the pictures acquired by ''Mariner 10'' that were used for mapping were obtained during the first encounter: those covering the southeast half of the qua ...

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] |
Olga Boznańska
Olga Boznańska (15 April 1865 – 26 October 1940) was a Polish painter of the turn of the 20th century. She was a notable painter in Poland and Europe, and was stylistically associated with the French impressionism, though she rejected this label. Early life Boznańska was born in Kraków during foreign partitions of Poland. She was the daughter of Adam Nowina Boznański, (from a noble Polish family but influenced by positivism to take up work as a railway engineer) and Eugénie ''née'' Mondan originally from Valence, France. Education and artistic training Boznańska learned drawing first from her mother who was a teacher in the convent school of Premonstratensians in Imbramowice near Kraków, then with Józef Siedlecki, Kazimierz Pochwalski and Antoni Piotrowski between 1883-6. She then studied at the Adrian Baraniecki School for Women. She débuted in 1886 at the Kraków Association of Friends of Fine Arts exhibition. From 1886–1890 she studied art in the private s ...

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] |
Hollows (Mercury)
Hollows are a landform on the planet Mercury, discovered during the '' MESSENGER'' mission that orbited the planet from 2011 to 2015. Hollows are typically clusters of rimless depressions with flat floors and haloes of bright (high albedo) material surrounding them. Hollows are thought to form by loss of volatiles from the surface by sublimation, caused by the intense solar radiation on the airless planet. They are some of the youngest features on Mercury. Hollows were first observed as bright areas within craters imaged by the Mariner 10 spacecraft in 1974, but the images were not of sufficient resolution to discern any detail. These craters include Balzac, Tyagaraja, Theophanes, Zeami, and Hopper.Dzurisin, D., 1977. Mercurian bright patches: Evidence for physio-chemical alteration of surface material?

Duccio (crater)
Duccio is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) on June 14, 2013. Duccio is named for the Italian painter Duccio di Buoninsegna. Carnegie Rupes cuts across Duccio crater. The crater Boznańska is to the east of Duccio, and Rubens Sir Peter Paul Rubens (; ; 28 June 1577 – 30 May 1640) was a Flemish artist and diplomat from the Duchy of Brabant in the Southern Netherlands (modern-day Belgium).

Namatjira (crater)
Namatjira is a crater on Mercury. It has a diameter of 34 kilometers. Its name was adopted by the International Astronomical Union (IAU) on September 25, 2015. Namatjira is named for the Australian aboriginal artist Albert Namatjira. An irregular depression is present in the center of Namatjira, which is similar to those within Navoi, Lermontov, Scarlatti, and Praxiteles. The depressions resemble those associated with volcanic explosions. The depression contains hollows. Namatjira lies on the western margin of a part of the Borealis Planitia. To the west of Namatjira is Boznańska crater, and to the south are the Victoria Rupes Victoria Rupes is an escarpment in the Victoria quadrangle of Mercury. The quadrangle was named after this escarpment, and the escarpment itself was named after the ''Victoria'', a ship used on the famous expedition of Ferdinand Magellan. Its na ....
