Dean Benjamin McLaughlin
Dean Benjamin McLaughlin (born October 25, 1901, Brooklyn, New York CIty; died December 8, 1965, Ann Arbor, Michigan, US) was an American astronomer. He was a professor of astronomy at the University of Michigan. He was the father of the science fiction author Dean B. McLaughlin, Jr. He received his B.S. (1923), his M.S. (1924) and his Ph.D. (1927) all from Michigan. McLaughlin married fellow astronomer Laura Elizabeth Hill in 1927. In 1954 he proposed the theory that there are volcanoes on Mars and that their eruptions change the albedo features called "mare" (The martian equivalent of Lunar mare). His proposal was partially confirmed in 1971 with the arrival of Mariner 9, which showed that strong winds could move dust around the planet, creating the changes of appearance formerly attributed to some kind of vegetatio A Impact crater, crater on Mars was named in his honor, as is the crater McLaughlin on the far side of the Moon and the asteroid 2024 McLaughlin.

McLaughlin (Martian Crater)
McLaughlin Crater is an old crater in the Oxia Palus quadrangle of Mars, located at . It is in diameter and deep. The crater was named after Dean B. McLaughlin, an American astronomer (1901-1965). The Mars Reconnaissance Orbiter has found evidence that the water came from beneath the surface between 3.7 billion and 4 billion years ago and remained long enough to make carbonate-related clay minerals found in layers. McLaughlin Crater, one of the deepest craters on Mars, contains Mg-Fe clays and carbonates that probably formed in a groundwater-fed alkaline lake. This type of lake could have had a massive biosphere of microscopic organisms.Michalski, J., J. Cuadros, P. Niles, J. Parnell, A. Rogers, S. Wright. 2013.

People From Brooklyn
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

University Of Michigan Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, H ...

Rossiter–McLaughlin Effect
The Rossiter–McLaughlin effect is a spectroscopic phenomenon observed when an object moves across the face of a star. Description The Rossiter–McLaughlin effect is a spectroscopic phenomenon observed when either an eclipsing binary's secondary star or an extrasolar planet is seen to transit across the face of the primary or parent star. As the main star rotates on its axis, one quadrant of its photosphere will be seen to be coming towards the viewer, and the other visible quadrant to be moving away. These motions produce blueshifts and redshifts, respectively, in the star's spectrum, usually observed as a broadening of the spectral lines. When the secondary star or planet transits the primary, it blocks part of the latter's disc, preventing some of the shifted light from reaching the observer. That causes the observed mean redshift of the primary star as a whole to vary from its normal value. As the transiting object moves across to the other side of the star's disc, the r ...

Richard Alfred Rossiter
Richard Alfred Rossiter (December 19, 1886 January 26, 1977) was an American astronomer, known for the Rossiter–McLaughlin effect. Rossiter served as director of the Lamont–Hussey Observatory from 1928 until 1952. Early life Rossiter was born in Oswego, New York, on December 19, 1886. He graduated from Wesleyan University in 1914, and married Jane van Dusen in 1915. He taught mathematics at Wesleyan Seminary for five years before enrolling in the astronomy program at the University of Michigan. He earned a master's degree in 1920, and a doctorate three years later. His doctoral dissertation, a study of the spectrum of Beta Lyrae, demonstrated that the shift that it exhibited could be accounted for by stellar rotation. Rossiter and his wife had two children, Laura and Alfred. Career Rossiter became the first director of the Lamont–Hussey Observatory in 1928. During this tenure at the observatory, he discovered more than 5,000 double stars. His ''Catalogue of Southern Doubl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2024 McLaughlin
2024 McLaughlin, provisional designation , is an asteroid from the inner regions of the asteroid belt, approximately 8 kilometer in diameter. It was discovered 23 October 1952, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, and named after American astronomer Dean Benjamin McLaughlin. Orbit and classification ''McLaughlin'' orbits the Sun in the inner main-belt at a distance of 2.0–2.6 AU once every 3 years and 6 months (1,295 days).

McLaughlin (lunar Crater)
McLaughlin is a lunar impact crater that is located just behind the northwestern rim on the far side of the Moon. This portion of the surface is sometimes brought into view of the Earth due to libration, and the area can then be viewed from a low angle under favorable lighting conditions. McLaughlin lies to the west-southwest of the crater Galvani. About two crater diameters due west lies Rynin. This is a heavily eroded crater with an irregular rim that is mark by a number of smaller impacts. The interior floor is generally level, except for a low right offset to the southeast of the midpoint, and some irregularities near the southwest and northern inner walls. The interior is marked by several tiny craterlets. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to McLaughlin.

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 ...
