Richard Anthony Proctor
Richard Anthony Proctor (23 March 1837 – 12 September 1888) was an English astronomer. He is best remembered for having produced one of the earliest maps of Mars in 1867 from 27 drawings by the English observer William Rutter Dawes. His map was later superseded by those of Giovanni Schiaparelli and Eugène Antoniadi and his nomenclature was dropped (for instance, his "Kaiser Sea" became Syrtis Major Planum). He used old drawings of Mars dating back to 1666 to try to determine the sidereal day of Mars. His final estimate, in 1873, was 24h 37m 22.713s, very close to the modern value of 24h 37m 22.663s. The crater Proctor on Mars is named after him. Biography Richard Proctor's father died in 1850 and his mother attended to his education. He was sent to King's College London and subsequently earned a scholarship at St John's College, Cambridge. He graduated in 1860 as 23rd wrangler. Proctor then read for the bar, but turned to astronomy and authorship instead, and in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelsea, London
Chelsea is an affluent area in west London, England, due south-west of Charing Cross by approximately 2.5 miles. It lies on the north bank of the River Thames and for postal purposes is part of the south-western postal area. Chelsea historically formed a manor and parish in the Ossulstone hundred of Middlesex, which became the Metropolitan Borough of Chelsea in 1900. It merged with the Metropolitan Borough of Kensington, forming the Royal Borough of Kensington and Chelsea upon the creation of Greater London in 1965. The exclusivity of Chelsea as a result of its high property prices historically resulted in the coining of the term "Sloane Ranger" in the 1970s to describe some of its residents, and some of those of nearby areas. Chelsea is home to one of the largest communities of Americans living outside the United States, with 6.53% of Chelsea residents having been born in the U.S. History Early history The word ''Chelsea'' (also formerly ''Chelceth'', ''Chelchith' ...

Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The outer atmosphere is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knowledge (magazine)
''Knowledge: An Illustrated Magazine of Science'' was a British popular science magazine published from 1881 to 1918. Founded by astronomer Richard A. Proctor, the magazine started as a weekly periodical, becoming monthly in 1885. The magazine was known for its extensive correspondence columns. Proctor himself, the first editor, was a significant contributor, and many of his discoveries or theoretical deductions first appeared in the magazine. Proctor was sometimes assisted in editorial duties by Edward Clodd. After Proctor's death in 1888, Arthur Cowper Ranyard took over editorship, then Harry Forbes Witherby after Ranyard's death.

Chamber's Journal
''Chambers's Edinburgh Journal'' was a weekly 16-page magazine started by William Chambers in 1832. The first edition was dated 4 February 1832, and priced at one penny. Topics included history, religion, language, and science. William was soon joined as joint editor by his brother Robert, who wrote many of the articles for the early issues, and within a few years the journal had a circulation of 84,000. From 1847 to 1849 it was edited by William Henry Wills. In 1854 the title was changed to ''Chambers's Journal of Popular Literature, Science, and Art'', and changed again to ''Chambers's Journal'' at the end of 1897. The journal was produced in Edinburgh until the late 1850s, by which time the author James Payn had taken over as editor, and production was moved to London. Serialised fiction from major authors, including Payn himself, became one of the journal's major attractions following his arrival. Among its long-standing contributors was Camilla Dufour Crosland Camilla D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Intellectual Observer
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Nebula
A nebula ('cloud' or 'fog' in Latin; pl. nebulae, nebulæ or nebulas) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, such as in the "Pillars of Creation" in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials "clump" together to form denser regions, which attract further matter, and eventually will become dense enough to form stars. The remaining material is then thought to form planets and other planetary system objects. Most nebulae are of vast size; some are hundreds of light-years in diameter. A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. Although denser than the space ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star
A star is an astronomical object comprising a luminous spheroid of plasma (physics), plasma held together by its gravity. The List of nearest stars and brown dwarfs, nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night sky, night, but their immense distances from Earth make them appear as fixed stars, fixed points of light. The most prominent stars have been categorised into constellations and asterism (astronomy), asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye, all within the Milky Way galaxy. A star's life star formation, begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Its stellar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteor
A meteoroid () is a small rocky or metallic body in outer space. Meteoroids are defined as objects significantly smaller than asteroids, ranging in size from grains to objects up to a meter wide. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars. When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of , aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". Meteors typically become visible when they are about 100 km above sea level. A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. A meteorite is the remains of a meteoroid th ...
