Horace Parnell Tuttle
Horace Parnell Tuttle (March 17, 1837 – August 16, 1923) was an American astronomer, an American Civil War veteran and brother of astronomer Charles Wesley Tuttle (November 1, 1829 – July 17, 1881). Biography Early life H. P. Tuttle was born at Newfield, Maine. His parents were Moses Tuttle and Mary Merrow. In 1845 Mary Merrow died, and four years later Moses Tuttle remarried and moved to Cambridge, Massachusetts. Charles Wesley Tuttle was an amateur astronomer who constructed his own telescope, and on a visit to the Harvard Observatory so impressed William Cranch Bond that by 1850 he was hired as an assistant observer. At Harvard Charles Wesley first proposed the existence of the interior "dusky ring" of Saturn. In 1853 he discovered a comet (C/1853 E1 Secchi), with independent discovery credited to Father Secchi, Rome. The following year Charles Wesley was forced to give up his astronomical career because of failing eyesight. He entered Harvard Law School and became U. S. ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

8P/Tuttle
8P/Tuttle (also known as Tuttle's Comet or Comet Tuttle) is a periodic comet with a 13.6-year orbit. It fits the classical definition of a Jupiter-family comet with an orbital period of less than 20 years, but does not fit the modern definition of (2 < TJupiter< 3). Its last passage was 27 August 2021 when it had a of 26 degrees at approximately 9. Two weeks later, on September 12, 2021, it was about from ...

Comets
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several milli ...

John Brashear
John Alfred Brashear (November 24, 1840 – April 8, 1920) was an American astronomer and instrument builder. Life and work Brashear was born in Brownsville, Pennsylvania, a town 35 miles (56 km) south of Pittsburgh along the Monongahela River. His father, Basil Brown Brashear, was a saddler, and his mother, Julia Smith Brashear, was a school teacher. He was the oldest of seven children. As a boy, John Brashear was heavily influenced by his maternal grandfather, Nathanial Smith, a clock repairer. When he was nine, his grandfather took him to view through the telescope of 'Squire' Joseph P. Wampler, who set up his traveling telescope in Brownsville. That influential view of the moon and the planet Saturn stayed with Brashear for the rest of his life. After receiving a common school education until age 15, he became an apprentice to a machinist and had mastered his trade at age 20. Beginning in 1861 Brashear worked as a millwright in a rolling steel mill in Pittsburgh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Dewey
George Dewey (December 26, 1837January 16, 1917) was Admiral of the Navy, the only person in United States history to have attained that rank. He is best known for his victory at the Battle of Manila Bay during the Spanish–American War, with the loss of only a single crewman on the American side. Dewey was born in Montpelier, Vermont. At age 15, Dewey's father enrolled him at Norwich University in Northfield, Vermont. Two years later Norwich expelled him for drunkenness and herding sheep into the barracks.

Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lalande Prize
The Lalande Prize (French: ''Prix Lalande'' also known as Lalande Medal) was an award for scientific advances in astronomy, given from 1802 until 1970 by the French Academy of Sciences. The prize was endowed by astronomer Jérôme Lalande in 1801, a few years before his death in 1807, to enable the Academy of Sciences to make an annual award "to the person who makes the most unusual observation or writes the most useful paper to further the progress of Astronomy, in France or elsewhere." The awarded amount grew in time: in 1918 the amount awarded was 1000 Francs, and by 1950, it was 10,000 francs. It was combined with the Valz Prize ''(Prix Valz)'' in 1970 to create the Lalande-Valz Prize and then with a further 122 foundation prizes in 1997, resulting in the establishment of the Grande Médaille. The Grande Medaille is not limited to the field of astronomy. Winners See also * List of astronomy awards * List of Nobel laureates—Nobel Prize The Nobel Prizes ( ; sv, No ...
