Martian Canal
During the late 19th and early 20th centuries, it was erroneously believed that there were "canals" on the planet Mars. These were a network of long straight lines in the equatorial regions from 60° north to 60° south latitude on Mars, observed by astronomers using early telescopes without photography. They were first described by the Italian astronomer Giovanni Schiaparelli during the opposition of 1877, and confirmed by later observers. Schiaparelli called these ''canali'' ("channels"), which was mis-translated into English as "canals". The Irish astronomer Charles E. Burton made some of the earliest drawings of straight-line features on Mars, although his drawings did not match Schiaparelli's. Around the turn of the century there was even speculation that they were engineering works, irrigation canals constructed by a civilization of intelligent aliens indigenous to Mars. By the early 20th century, improved astronomical observations revealed the "canals" to be an optical ill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albedo Feature
An albedo feature is a large area on the surface of a planet (or other Solar System body) which shows a contrast in brightness or darkness (albedo) with adjacent areas. Historically, albedo features were the first (and usually only) features to be seen and named on Mars and Mercury. Early classical maps (such as those of Schiaparelli and Antoniadi) showed only albedo features, and it was not until the arrival of space probes that other surface features such as craters could be seen. On bodies other than Mars and Mercury, an albedo feature is sometimes called a regio. On bodies with a very thick atmosphere like Venus or Titan, permanent albedo features cannot be seen using ordinary optical telescopes because the surface is not visible, and only clouds and other transient atmospheric phenomena are seen. The '' Cassini–Huygens'' probe observed multiple albedo features on Titan after its arrival in Saturn's orbit in 2004. The first albedo feature ever seen on another plane ...

Center For Inquiry
The Center for Inquiry (CFI) is a US nonprofit organization that works to mitigate belief in pseudoscience and the paranormal, as well as to fight the influence of religion in government. History The Center for Inquiry was established in 1991 by atheist philosopher and author Paul Kurtz. It brought together two organizations: the Committee for the Scientific Investigation of Claims of the Paranormal (founded by Kurtz in 1976) and the Council for Secular Humanism (founded by Kurtz in 1980). In January 2016, CFI announced that it was merging with the Richard Dawkins Foundation for Reason and Science. In June 2009, Kurtz left CFI over a conflict with then-CEO Ronald A. Lindsay. Committee for Skeptical Inquiry Through the Committee for Skeptical Inquiry (CSI), and its journal, ''Skeptical Inquirer'' magazine, published by the Center for Inquiry, CSI examines evidential claims of the paranormal or supernormal, including psychics, ghosts, telepathy, clairvoyance, UFOs, and ...

Skeptical Inquirer
''Skeptical Inquirer'' is a bimonthly American general-audience magazine published by the Committee for Skeptical Inquiry (CSI) with the subtitle: ''The Magazine for Science and Reason''. Mission statement and goals Daniel Loxton, writing in 2013 about the mission and goals of the skeptical movement, criticized the idea that people wanted to read about the paranormal, Uri Geller and crystal skulls not being relevant any longer. Paul Kurtz in 2009 seemed to share this sentiment and stated that the organization would still research some paranormal subjects as they have expertise in this area, but they would begin to investigate other areas. S.I. "has reached an historic juncture: the recognition that there is a critical need to change our direction." While editor Frazier did expand the scope of the magazine to include topics less paranormal and more that were an attack on science and critical thinking such as climate change denialism, conspiracy theories and the influence of the ...

Monthly Notices Of The Royal Astronomical Society
''Monthly Notices of the Royal Astronomical Society'' (MNRAS) is a peer-reviewed scientific journal covering research in astronomy and astrophysics. It has been in continuous existence since 1827 and publishes letters and papers reporting original research in relevant fields. Despite the name, the journal is no longer monthly, nor does it carry the notices of the Royal Astronomical Society. History The first issue of MNRAS was published on 9 February 1827 as ''Monthly Notices of the Astronomical Society of London'' and it has been in continuous publication ever since. It took its current name from the second volume, after the Astronomical Society of London became the Royal Astronomical Society (RAS). Until 1960 it carried the monthly notices of the RAS, at which time these were transferred to the newly established ''Quarterly Journal of the Royal Astronomical Society'' (1960–1996) and then to its successor journal ''Astronomy & Geophysics'' (since 1997). Until 1965, MNRAS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Walter Maunder
Edward Walter Maunder (12 April 1851 – 21 March 1928) was an English astronomer. His study of sunspots and the solar magnetic cycle led to his identification of the period from 1645 to 1715 that is now known as the Maunder Minimum. Early and personal life Maunder was born in 1851, in London, the youngest child of a minister of the Wesleyan Society. He attended King's College London but never graduated. He took a job in a London bank to finance his studies. In 1873 Maunder returned to the Royal Observatory, taking a position as a spectroscopic assistant. Shortly after, in 1875, he married Edith Hannah Bustin, who gave birth to six children: four sons (one of whom died in infancy) and two daughters. Following the death of Edith in 1888, in 1890 he met Annie Scott Dill Russell (later Annie Russell Maunder, 1868–1947), a mathematician and astronomer educated at Girton College in Cambridge, with whom he collaborated for the remainder of his life. She worked as a " lady compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Edward Evans

Edward Emerson Barnard
Edward Emerson Barnard (December 16, 1857 – February 6, 1923) was an American astronomer. He was commonly known as E. E. Barnard, and was recognized as a gifted observational astronomer. He is best known for his discovery of the high proper motion of Barnard's Star in 1916, which is named in his honor. Early life Barnard was born in Nashville, Tennessee, to Reuben Barnard and Elizabeth Jane Barnard (''née'' Haywood), and had one brother. His father died three months before his birth, so he grew up in an impoverished family and did not receive much in the way of formal education. His first interest was in the field of photography, and he became a photographer's assistant at the age of nine. He later developed an interest in astronomy. In 1876 he purchased a refractor telescope, and in 1881 he discovered his first comet, but failed to announce his discovery. He found his second comet later the same year and a third in 1882. While he was still working at a photography studio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal
The Panama Canal ( es, Canal de Panamá, link=no) is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Strait. Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the ...

Suez Canal
The Suez Canal ( arz, قَنَاةُ ٱلسُّوَيْسِ, ') is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia. The long canal is a popular trade route between Europe and Asia. In 1858, Ferdinand de Lesseps formed the Suez Canal Company for the express purpose of building the canal. Construction of the canal lasted from 1859 to 1869. The canal officially opened on 17 November 1869. It offers vessels a direct route between the North Atlantic and northern Indian oceans via the Mediterranean Sea and the Red Sea, avoiding the South Atlantic and southern Indian oceans and reducing the journey distance from the Arabian Sea to London by approximately , or 10 days at to 8 days at . The canal extends from the northern terminus of Port Said to the southern terminus of Port Tewfik at the city of Suez. In 2021, more than 20,600 vessels traversed the canal (an average of 56 per day). T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
