Rosina Dafter
Rosina Dafter (née Fitton), FRAS (15 March 1875 - 9 June 1959) was an astronomer and the first Australian woman to be made a fellow of the Royal Astronomical Society. She re-discovered the Pons-Winnecke comet in 1927 and was responsible for the discovery of previously unobserved variable stars in the Carina constellation. Life Dafter was born in London to Margaret and Richard Fitton, a pianoforte maker. She was educated at Holy Trinity Church School in London and started work as a dress designer before her marriage to John Albert Dafter on 20 November 1898. The couple arrived in Australia in 1910 and settled in Northgate with their two foster sons who were merchant mariners. While she had an interest in stars from childhood and studied mathematics as a hobby, it was not until her arrival in Australia that Dafter sought advice and began teaching herself astronomy. In 1923, Dafter was elected a member of the British Astronomical Association which had a branch in New South Wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London
London is the capital and List of urban areas in the United Kingdom, largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia.

Barrier Miner
''The Barrier Miner'' was a daily broadsheet newspaper published in Broken Hill in far western New South Wales from 1888 to 1974. History First published on 28 February 1888, ''The Barrier Miner'' was published continuously until 25 November 1974. Copies are available on microfilm and online via Trove Digitised Newspapers. The paper was revived briefly in 2005; an index to births deaths and marriages has been prepared which also notes additional publication dates between 16 December 2005 and 31 July 2008. The paper closed down for a second time in 2008 with the managing director, Margaret McBride stating that "...due to commercial reasons the paper would no longer service Broken Hill and the region...". ''The Barrier Miner'' served the growing mining community of Broken Hill, when the area was found to have lead ore and traces of silver. It was not until late 1884 or early 1885 that rich quantities of silver were found and the Broken Hill Proprietary Company (BHP) was floated ...

The Queenslander
''The Queenslander'' was the weekly summary and literary edition of the '' Brisbane Courier'', the leading journal in the colony—and later, federal state—of Queensland since the 1850s. ''The Queenslander'' was launched by the Brisbane Newspaper Company in 1866, and discontinued in 1939. History ''The Queenslander'' was first published on 3 February 1866 in Brisbane by Thomas Blacket Stephens. The last edition was printed on 22 February 1939. In a country the size of Australia, a daily newspaper of some prominence could only reach the bush and outlying districts if it also published a weekly edition. Yet ''The Queenslander'', under the managing editorship of Gresley Lukin—managing editor from November 1873 until December 1880—also came to find additional use as a literary magazine. In September 1919, a series of aerial photographs of Brisbane and its surrounding suburbs were published under the title, ''Brisbane By Air''. The photographs were taken by the newspape ...

Astronomy
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. ...

Photometry (astronomy)
Photometry, from Greek '' photo-'' ("light") and '' -metry'' ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects. This light is measured through a telescope using a photometer, often made using electronic devices such as a CCD photometer or a photoelectric photometer that converts light into an electric current by the photoelectric effect. When calibrated against standard stars (or other light sources) of known intensity and colour, photometers can measure the brightness or apparent magnitude of celestial objects. The methods used to perform photometry depend on the wavelength region under study. At its most basic, photometry is conducted by gathering light and passing it through specialized photometric optical bandpass filters, and then capturing and recording the light energy with a photosensitive instrument. Standard sets of passbands (called a photometric system) are defined to all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Broken Hill
Broken Hill is an inland mining city in the far west of outback New South Wales, Australia. It is near the border with South Australia on the crossing of the Barrier Highway (A32) and the Silver City Highway (B79), in the Barrier Range. It is 315m above sea level, with a hot desert climate, and an average rainfall of 235mm. The closest major city is Adelaide, the capital of South Australia, which is more than 500km to the southwest and linked via route A32. The town is prominent in Australia's mining, industrial relations and economic history after the discovery of silver ore led to the opening of various mines, thus establishing Broken Hill's recognition as a prosperous mining town well into the 1990s. Despite experiencing a slowing economic situation into the late 1990s and 2000s, Broken Hill itself was listed on the National Heritage List in 2015 and remains Australia's longest running mining town. Broken Hill, historically considered one of Australia's boomtowns, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Association Of Variable Star Observers
The American Association of Variable Star Observers (AAVSO) is an international nonprofit organization, founded in 1911, focused on coordinating, analyzing, publishing, and archiving variable star observations made largely by amateur astronomers. The AAVSO creates records that establish light curves depicting the variation in brightness of a star over time, and makes them available to professional astronomers, researchers, and educators. Since professional astronomers do not have the time or the resources to monitor every variable star, astronomy is one of the few sciences where amateurs can make genuine contributions to scientific research. During 2011, the 100th year of the AAVSO's existence, the 20-millionth variable star observation was received into the database. The AAVSO International Database (AID) stores over 35 million observations as of 2019. The organization receives nearly 1,000,000 observations annually from around 2,000 professional and amateur observers and is q ...
