David Thackeray
Andrew David Thackeray (19 June 1910 – 21 February 1978), was an astronomer trained at Cambridge University. He served as director of the Radcliffe Observatory for 23 years. Career Thackeray went to school at Eton College, where he observed meteors for the British Astronomical Association. He went on to study mathematics at King's College, Cambridge. He received a PhD on theoretical stellar spectroscopy in 1937 from the Solar Physics Laboratory in Cambridge. During his studies he worked at the Mount Wilson Observatory in California from 1934 to 1936. He was Assistant Director of the Solar Physics Observatory at Cambridge Observatory from 1937 to 1948. He was then director of the Radcliffe Observatory, Pretoria from 1951 until it was merged with the Royal Observatory, Cape of Good Hope in 1974 to form the South African Astronomical Observatory. He became an honorary professor of the University of Cape Town and, a few days before his death, an Associate of the Royal Astronomi ...

Quarterly Journal Of The Royal Astronomical Society
''Astronomy & Geophysics'' (''A&G'') is a scientific journal and trade magazine published on behalf of the Royal Astronomical Society (RAS) by Oxford University Press. It is distributed bimonthly to members of the RAS. A&G publishes content of interest to professional astronomers and geophysicists, including: news reports, interviews, topical reviews, historical investigations, obituaries, meeting reports and updates on the activities of the RAS. Full-length articles are peer-reviewed, but A&G does not publish original research papers. A&G was established in 1997 as a glossy magazine replacement for the ''Quarterly Journal of the Royal Astronomical Society'' (QJRAS; 1960–1996); it continues the same volume numbering from QJRAS. The editor is Sue Bowler of the University of Leeds. Scope The journal covers astronomy, astrophysics, cosmology, planetary science, solar-terrestrial physics, global and regional geophysics, and the history of these subjects. It also publishes them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the electromagnetic spectrum, spectrum of electromagnetic radiation, including Visible light astronomy, visible light, Ultraviolet astronomy, ultraviolet, X-ray astronomy, X-ray, Infrared astronomy, infrared and Radio astronomy, radio waves that radiant energy, radiate from stars and other celestial objects. A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance and luminosity. Spectroscopy can show the velocity of motion towards or away from the observer by measuring the Doppler effect, Doppler shift. Spectroscopy is also used to study the physical properties of many other types of celestial objects such as planets, nebulae, Galaxy, galaxies, and Active galactic nucleus, active galactic nuclei. Background Astronomical spectroscopy is used to measure three major bands of radiation in the electromagnetic spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South is one of the cardinal directions or compass points. The direction is the opposite of north North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating Direction (geometry), direction or geography. Etymology T ... and is perpendicular to both west and east. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic language, Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European language, Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', ), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָ ...
