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 African Astronomers
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 ...

Mary Acworth Evershed
Mary Acworth Evershed (; 1 January 1867 – 25 October 1949) was a British astronomer and scholar. Her work on Dante Alighieri was written under the pen name M.A. Orr. Early life Mary Acworth Orr was born to Lucy Erskine Acworth (1841–1904) and Andrew Orr (''ca.'' 1830–1870) on 1 January 1867 at Plymouth Hoe. Her father was an officer in the Royal Artillery, who married in 1859. Mary grew up in Wimborne and South Stoke in Somerset. Mary’s youngest brother was the colonial administrator Charles William James Orr. When she was 20, Orr travelled abroad with her sisters and, when in Florence (1888–1890) began a study of the works of Dante, which led to her lifelong interest in astronomical references in Dante's poems. Astronomical career In 1890, Orr moved with her family to Australia. She found there was no good guide to the southern stars, so wrote ''An Easy Guide to the Southern Stars'', with the encouragement of John Tebbutt, the leading astronomer in Australia at t ...

Chelsea, London
Chelsea is an area in West London, England, due south-west of Kilometre zero#Great Britain, Charing Cross by approximately . It lies on the north bank of the River Thames and for postal purposes is part of the SW postcode area, south-western postal area. Chelsea historically formed a manor and parish in the Ossulstone hundred of Middlesex, which became the Metropolitan Borough of Chelsea in 1900. It merged with the Metropolitan Borough of Kensington, forming the Royal Borough of Kensington and Chelsea upon the creation of Greater London in 1965. The exclusivity of Chelsea as a result of its high property prices historically resulted in the coining of the term "Sloane Ranger" in the 1970s to describe some of its residents, and some of those of nearby areas. Chelsea is home to one of the largest communities of Americans living outside the United States, with 6.53% of Chelsea residents having been born in the U.S. History Early history The word ''Chelsea'' (also formerly ' ...

Monthly Notices Of The Royal Astronomical Society
''Monthly Notices of the Royal Astronomical Society'' (MNRAS) is a peer-reviewed scientific journal in astronomy, astrophysics and related fields. It publishes original research in two formats: papers (of any length) and letters (limited to five pages). MNRAS publishes more articles per year than any other astronomy journal. The learned society journal has been in continuous existence since 1827 and became online only in 2020. It operates as a partnership between the Royal Astronomical Society (RAS), who select and peer-review the contents, and Oxford University Press (OUP), who publish and market the journal. Despite its name, MNRAS is no longer monthly, nor does it carry the notices of the RAS. In 2024 MNRAS became a purely gold open access journal. 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 vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thackeray's Globules
IC 2944, also known as the Running Chicken Nebula, the Lambda Centauri Nebula or the λ Centauri Nebula, is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star λ Centauri. It features Bok globules, which are frequently a site of active star formation. However, no evidence for star formation has been found in any of the globules in IC 2944. Other designations for IC 2944 include RCW 62, G40 and G42. The ESO Very Large Telescope image on the right is a close up of a set of Bok globules discovered in IC 2944 by astronomer A. David Thackeray in 1950. These globules are now known as Thackeray's Globules. In 2MASS images, 6 stars are visible within the largest globule. The region of nebulosity visible in modern images includes both IC 2944 and IC 2948, as well as the fainter IC 2872 nearby. IC 2948 is the brightest emission and reflection nebulae towards the southeast, while IC 2944 is the cluster of stars and surrounding nebulosity ...
