Astronomy And Astrophysics
''Astronomy & Astrophysics'' is a monthly peer-reviewed scientific journal covering theoretical, observational, and instrumental astronomy and astrophysics. 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, F ...

Astronomy And Astro-Physics
Goodsell Observatory is an observatory at Carleton College in Northfield, Minnesota, United States. It was constructed in 1887 and was, at the time, the largest observatory in the state of Minnesota. The Goodsell Observatory and its predecessor, a smaller observatory that opened in 1878, served as a widely consulted timekeeping station, bringing national prominence to Carleton College in the late 19th and early 20th centuries. Goodsell Observatory was listed on the National Register of Historic Places in 1975 for its national significance in the themes of architecture, communications, education, engineering, literature, and science. It was nominated for being one of the nation's few intact 19th-century observatories (complete with a large collection of vintage scientific equipment); and for its critical timekeeping service, its association with scientific literature (founder William W. Payne (astronomer), William W. Payne also founded the journal ''Popular Astronomy (US magazi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosetta (spacecraft)
''Rosetta'' was a space probe built by the European Space Agency launched on 2 March 2004. Along with ''Philae'', its lander module, ''Rosetta'' performed a detailed study of comet 67P/Churyumov–Gerasimenko (67P). During its journey to the comet, the spacecraft performed flybys of Earth, Mars, and the asteroids 21 Lutetia and 2867 Šteins. It was launched as the third cornerstone mission of the ESA's Horizon 2000 programme, after ''SOHO'Cluster'' and ''XMM-Newton''. On 6 August 2014, the spacecraft reached the comet and performed a series of manoeuvers to eventually orbit the comet at distances of . On 12 November, its lander module ''Philae'' performed the first successful landing on a comet, though its battery power ran out two days later. Communications with ''Philae'' were briefly restored in June and July 2015, but due to diminishing solar power, ''Rosetta'' communications module with the lander was turned off on 27 July 2016. On 30 September 2016, the ''Rosetta'' spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Delayed Open Access Journal
Delayed open-access journals are traditional subscription-based journals that provide free online access upon the expiry of an embargo period following the initial publication date. Details The embargo period before an article is made available for free can vary from a few months to two or more years. In a 2013 study, 77.8% of delayed open access journals analyzed had an embargo of 12 months or less. 85.4% had an embargo period of 24 months or less. A journal subscription or an individual article purchase fee would be required to access the materials before this embargo period ends. Some delayed access journals also deposit their publications in open repositories when the author is bound by a delayed open-access mandate. The rationale for the access delay is to provide eventual access to all would-be users while still requiring the institutions of researchers who need immediate access to keep paying the subscriptions that cover the costs of publication. The marginal costs of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
