Robert A. Haag
Robert A. Haag (born 1956) is an American famous for collecting meteorites. Some meteorites acquired from Haag are currently on display in the Smithsonian. Detainment Haag was detained as a preventative measure pending judgement in Argentina charged with removing protected rocks (the 37 ton El Chaco meteorite). Haag claimed he was set up by an Argentinian mineral dealer, who had asserted the meteorite belonged to the land owner and the dealer entered into an arrangement to broker the sale to Haag for $200,000. Haag was released from detainment and left Argentina after paying bail and having his passport returned. Achievements Haag was the first private citizen and meteorite hunter to discover a Lunar meteorite, known as Calcalong Creek. It was discovered among other meteorites coming out of the Australian Millbillillie meteorite (eucrite achondrite) strewn field. It was bought as a Millbillillie by Haag, but he discovered it was a lunar meteorite. He was also one of the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

Millbillillie (meteorite)
Millbillillie meteorite is a meteorite named after the cattle station in Western Australia on which it fell in October 1960. It is classified as a eucrite achondrite, a kind of stony meteorite. History A fireball was observed "with sparks coming off it" by two stationworkers while they were opening a gate in the boundary fence on a track between Millbillillie and Jundee cattle stations. The object fell on a plain to the north. No search was made at the time but in 1970 and 1971 locals found two stones; Aboriginals have found others since. The largest stone weighed . It and a smaller one of are held by the Western Australian Museum.

Omni (magazine)
''Omni'' was a science and science fiction magazine published in its domestic American market as well as the UK. It contained articles on science, parapsychology, and short works of science fiction and fantasy. It was published as a print version between October 1978 and 1995. The first ''Omni'' e-magazine was published on CompuServe in 1986 and the magazine switched to a purely online presence in 1996. It ceased publication abruptly in late 1997, following the death of co-founder Kathy Keeton; activity on the magazine's website ended the following April. History Concept ''Omni'' was founded by Kathy Keeton and her long-time collaborator and future husband Bob Guccione, the publisher of ''Penthouse'' magazine. The initial concept came from Keeton, who wanted a magazine "that explored all realms of science and the paranormal, that delved into all corners of the unknown and projected some of those discoveries into fiction".

Strewn Field
The term strewn field indicates the area where meteorites from a single fall are dispersed. It is also often used for the area containing tektites produced by large meteorite impact.''Tektites in the geological record: showers of glass from the sky''. Gerald Joseph Home McCall. Geological Society of London, 2001page 10/ref> Formation There are two strewnfield formation mechanisms: # Mid-air fragmentation: when a large meteoroid enters the atmosphere it often fragments into many pieces before touching the ground due to thermal shock. This mid-air explosion disperses material over a large oval-shaped area. The long axis of this oval is along the flight path of the meteoroid. When multiple-explosions occur, the material can be found in several overlapping ovals. # Impact fragmentation: when there is almost no mid-air fragmentation the fragmentation can occur upon impact. In this case the strewnfield shape can be different, usually circular. (e.g. Canyon Diablo at Meteor Crater; Austra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achondrite
An achondrite is a stony meteorite that does not contain chondrules. It consists of material similar to terrestrial basalts or plutonic rocks and has been differentiated and reprocessed to a lesser or greater degree due to melting and recrystallization on or within meteorite parent bodies. As a result, achondrites have distinct textures and mineralogies indicative of igneous processes. Achondrites account for about 8% of meteorites overall, and the majority (about two-thirds) of them are HED meteorites, possibly originating from the crust of asteroid 4 Vesta. Other types include Martian, Lunar, and several types thought to originate from as-yet unidentified asteroids. These groups have been determined on the basis of e.g. the Fe/ Mn chemical ratio and the 17O/18O oxygen isotope ratios, thought to be characteristic "fingerprints" for each parent body. Classification Achondrites are classified into the following groups:O. Richard Norton. The Cambridge encyclopedia of meteorites. U ...

Eucrite
Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid 4 Vesta and are part of the HED meteorite clan. They are the most common achondrite group with over 100 meteorites found. Eucrites consist of basaltic rock from the crust of 4 Vesta or a similar parent body. They are mostly composed of calcium-poor pyroxene, pigeonite, and calcium-rich plagioclase ( anorthite). Based on differences of chemical composition and features of the component crystals, they are subdivided into several groups: * Non-cumulate eucrites are the most common variety and can be subdivided further: ** Main series eucrites formed near the surface and are mostly regolith breccias lithified under the pressure of overlying newer deposits. ** Stannern trend eucrites are a rare variety. ** Nuevo Laredo trend eucrites are thought to come from deeper layers of 4 Vesta's crust, and are a transition group towards the cumulate eucrites. * Cumulate eucrites are rare typ ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Lunar Meteorite
A lunar meteorite is a meteorite that is known to have originated on the Moon. A meteorite hitting the Moon is normally classified as a transient lunar phenomenon. Discovery In January 1982, John Schutt, leading an expedition in Antarctica for the ANSMET program, found a meteorite that he recognized to be unusual. Shortly thereafter, the meteorite now called Allan Hills 81005 was sent to Washington, DC, where Smithsonian Institution geochemist Brian Mason recognized that the sample was unlike any other known meteorite and resembled some rocks brought back from the Moon by the Apollo program. Several years later, Japanese scientists recognized that they had also collected a lunar meteorite, Yamato 791197, during the 1979 field season in Antarctica. , 371 lunar meteorites have been discovered, perhaps representing more than 30 separate meteorite falls (i.e., many of the stones are "paired" fragments of the same meteoroid). The total mass is more than . All lunar meteorites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
