William Frederick Denning
William Frederick Denning (25 November 1848 – 9 June 1931) was a British amateur astronomer who achieved considerable success without formal scientific training. He is known for his catalogues of meteor radiants, observations of Jupiter's red spot, and for the discovery of five comets. Outside astronomy, as a young man, Denning showed prowess at cricket to the extent W G Grace invited him to play for Gloucestershire. However Denning’s retiring nature made him decline the offer. Career Denning devoted a great deal of time to searching for comets, and discovered five of them, including the periodic comet 72P/Denning–Fujikawa and the lost comet D/1894 F1. The latter was the last comet discovered on British soil until the discoveries of George Alcock. Denning also studied meteors and novae, discovering Nova Cygni 1920 (V476 Cyg). From 1869 Denning held the combined post of secretary and treasurer of the short-lived Observing Astronomical Society. Denning was elected to the ...

Punch (magazine)
''Punch, or The London Charivari'' was a British weekly magazine of humour and satire established in 1841 by Henry Mayhew and wood-engraver Ebenezer Landells. Historically, it was most influential in the 1840s and 1850s, when it helped to coin the term " cartoon" in its modern sense as a humorous illustration. From 1850, John Tenniel was the chief cartoon artist at the magazine for over 50 years. After the 1940s, when its circulation peaked, it went into a long decline, closing in 1992. It was revived in 1996, but closed again in 2002. History ''Punch'' was founded on 17 July 1841 by Henry Mayhew and wood-engraver Ebenezer Landells, on an initial investment of £25. It was jointly edited by Mayhew and Mark Lemon. It was subtitled ''The London Charivari'' in homage to Charles Philipon's French satirical humour magazine ''Le Charivari''. Reflecting their satiric and humorous intent, the two editors took for their name and masthead the anarchic glove puppet, Mr. Punch, of Punc ...

Nova Cygni 1920
V476 Cygni or Nova Cygni 1920 was a nova which occurred in the constellation Cygnus in 1920. It was discovered by William Frederick Denning, an English amateur astronomer, at 09:30 GMT on 20 August 1920, at which time it had a magnitude of 3.7. It reached a peak brightness of magnitude 1.7 on 23 August 1920. Its quiescent brightness is magnitude 17.09. V476 Cygni's light curve is quite unusual, showing a rapid decline from maximum brightness, followed by a slow nearly linear fading. It is classified as a very fast nova, with a very long tail. The light curve shows a "dust dip", a fast decline to a local brightness minimum, then a small increase in brightness, and finally a long, slow decline. This dust dip is believed to is believed to coincide with the formation of dust in the material ejected from the nova as it moves away from the star and cools. All novae consist of a close binary star pair, with a white dwarf star and a "donor" star orbiting each other. The star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Medal Of The Royal Astronomical Society
The Gold Medal of the Royal Astronomical Society is the highest award given by the Royal Astronomical Society (RAS). The RAS Council have "complete freedom as to the grounds on which it is awarded" and it can be awarded for any reason. Past awards have been given for "outstanding personal researches in the fields of astronomy and geophysics" as well as general contributions to astronomy and geophysics "that may be made through leadership in research programmes, through education and through scientific administration". It has been awarded both for research that has taken a lifetime (it has most frequently been given to recognise an extraordinary lifetime achievement), and for specific pieces of research. History The RAS was founded in 1820 and the first Gold Medals were awarded in 1824. Silver medals were also awarded in 1824 and 1827, but that practice was quickly abandoned, instead the RAS established other awards. In the early years, more than one medal was often awarded in a ...

Smithsonian Astrophysical Observatory
The Smithsonian Astrophysical Observatory (SAO) is a research institute of the Smithsonian Institution, concentrating on astrophysical studies including galactic and extragalactic astronomy, cosmology, solar, earth and planetary sciences, theory and instrumentation, using observations at wavelengths from the highest energy gamma rays to the radio, along with gravitational waves. Established in Washington, D.C., in 1890, the SAO moved its headquarters in 1955 to Cambridge, Massachusetts, where its research is a collaboration with the Harvard College Observatory (HCO) and the Harvard University Department of Astronomy. In 1973, the Smithsonian and Harvard formalized the collaboration as the Center for Astrophysics , Harvard & Smithsonian (CfA) under a single Director.

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] |
Journal Des Observateurs

The journal is run by a Board of Directors representing 27 sponsoring countries plus a representative of the European Southern Observatory. The journal is published by EDP Sciences and the editor-in-chief is . History Origins ''Astronomy and Astrophysics'' (A&A) was created as an answer to the publishing scenario found in Europe in the 1960s. At that time, multiple journals were being published in several countries around the continent. These journals usually had a limited number of subscribers, and published articles in languages other than English, resulting in a small number of citations compared to American and British journals. Starting in 1963, conversations between astronomers from European countries assessed the need for a common astronomical journal. On 8 April 1968, leading astronomers from Belgium, Denmark, Fr ...
