Sydney
Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders". The 2021 census recorded the population of Greater Sydney as 5,231,150, meaning the city is home to approximately 66% of the state's population. Estimated resident population, 30 June 2017. Nicknames of the city include the 'Emerald City' and the 'Harbour City'. Aboriginal Australians have inhabited the Greater Sydney region for at least 30,000 years, and Aboriginal engravings and cultural sites are common throughout Greater Sydney. The traditional custodians of the land on which modern Sydney stands are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compass
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers. Compasses often show angles in degrees: north corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearings which are commonly stated in degrees. If local variation between magnetic north and true north is known, then direction of magnetic north also gives direction of true north. Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since c. 206 BC),Li Shu-hua, p. 176 and later adopted for navigation by the Song Dynasty Chinese during the 11th centur ...

Milky Way
The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term ''Milky Way'' is a translation of the Latin ', from the Greek ('), meaning "milky circle". From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies. The Milky Way is a barred spiral galaxy with an estimated D25 isophotal diameter of , but only about 1,000 light years thick at the spiral arms (more at the bulg ...

William Dawes (British Marines Officer)
William Nicolas Dawes (1762–1836) was an officer of the British Marines, an astronomer, engineer, botanist, surveyor, explorer, abolitionist, and colonial administrator. He traveled to New South Wales with the First Fleet on board . Early life William Dawes was born at Portsmouth, Hampshire, in early 1762, the eldest child of Benjamin and Elizabeth (Sinnatt) Dawes. He was christened there on 17 March 1762. His father was a clerk of works in the Ordnance Office at Portsmouth. He joined the marines as a Second Lieutenant on 2 September 1779. He was wounded in action against the French Navy under the Comte de Grasse at the Battle of the Chesapeake in 1781. Dawes volunteered for service with the New South Wales Marine Corps, which accompanied the First Fleet. Because he was known as a competent astronomer, he was asked to establish an observatory and make astronomical observations on the voyage and in New South Wales. New South Wales From March 1788 Dawes was employed in the sett ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ARC Centre Of Excellence For All-Sky Astrophysics
ARC Centre of Excellence for All-Sky Astrophysics (or CAASTRO) was a collaboration of international astronomers dedicated to wide field astronomy. It was formally launched on 12 September 2011, at Sydney Observatory and ceased in 2018. Aims CAASTRO aimed to be an international leader in wide-field astronomy. It planned to deliver transformational new science by bringing together unique expertise in radio astronomy, optical astronomy, theoretical astrophysics and computation. Programmes CAASTRO pursued three interlinked scientific programmes, each of which could be addressed only with the all-sky perspective provided by wide-field telescopes: * The Evolving Universe: When did the first galaxies form, and how have they then evolved? * The Dynamic Universe: What is the high-energy physics that drives change in the Universe? * The Dark Universe: What are the Dark Energy and Dark Matter that dominate the cosmos?

Australian Research Council
The Australian Research Council (ARC) is the primary non-medical research funding agency of the Australian Government, distributing more than in grants each year. The Council was established by the ''Australian Research Council Act 2001'', and provides competitive research funding to academics and researchers at Australian universities. Most health and medical research in Australia is funded by the more specialised National Health and Medical Research Council (NHMRC), which operates under a separate budget. ARC does not directly fund researchers, but however allocates funds to individual schemes with specialised scopes, such as Discover (fundamental and empirical research) and Linkage (domestic and international collaborative projects). Most of these schemes fall under the National Competitive Grants Program (NCGP), whereby institutions must compete amongst each other for funding. ARC also administers the Excellence in Research for Australia framework (ERA), which provides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harvard Observatory
The Harvard College Observatory (HCO) is an institution managing a complex of buildings and multiple instruments used for astronomical research by the Harvard University Department of Astronomy. It is located in Cambridge, Massachusetts, United States, and was founded in 1839. With the Smithsonian Astrophysical Observatory, it forms part of the Center for Astrophysics Harvard & Smithsonian. HCO houses a collection of approximately 500,000 astronomical plates taken between the mid-1880s and 1989 (with a gap from 1953–1968). This 100-year coverage is a unique resource for studying temporal variations in the universe. The Digital Access to a Sky Century @ Harvard project is digitally scanning and archiving these photographic plates.
