Noctua (constellation)
Noctua (Latin: ''owl'') was a constellation near the tail of Hydra in the southern celestial hemisphere, but is no longer recognized. It was introduced by Alexander Jamieson in his 1822 work, ''A Celestial Atlas'', and appeared in a derived collection of illustrated cards, ''Urania's Mirror''. Now designated Asterism ''a'', the owl was composed of the stars 4 Librae and 54–57 Hydrae, which range from 4th to 6th magnitude. The French astronomer Pierre Charles Le Monnier Pierre Charles Le Monnier (; 23 November 1715 – 3 April 1799) was a French astronomer. His name is sometimes given as Lemonnier. Biography Le Monnier was born in Paris, where his father Pierre (1675–1757), also an astronomer, was professor ... had introduced a bird on Hydra's tail as the constellation Solitaire, named for the extinct flightless bird, the Rodrigues solitaire, but the image was that of a rock thrush which had been classified in the genus ''Turdus'', giving rise to the constellation name ...

Flightless Bird
Flightless birds are birds that through evolution lost the ability to fly. There are over 60 extant species, including the well known ratites (ostriches, emu, cassowaries, rheas, and kiwi) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7 g). The largest (both heaviest and tallest) flightless bird, which is also the largest living bird, is the ostrich (2.7 m, 156 kg). Many domesticated birds, such as the domestic chicken and domestic duck, have lost the ability to fly for extended periods, although their ancestral species, the red junglefowl and mallard, respectively, are capable of extended flight. A few particularly bred birds, such as the Broad Breasted White turkey, have become totally flightless as a result of selective breeding; the birds were bred to grow massive breast meat that weighs too much for the bird's wings to support in flight. Flightlessness has evolved in many different birds independently, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecliptic Coordinate System
The ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations of Solar System objects. Because most planets (except Mercury) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic, using it as the fundamental plane is convenient. The system's origin can be the center of either the Sun or Earth, its primary direction is towards the vernal (March) equinox, and it has a right-hand convention. It may be implemented in spherical or rectangular coordinates. Primary direction The celestial equator and the ecliptic are slowly moving due to perturbing forces on the Earth, therefore the orientation of the primary direction, their intersection at the Northern Hemisphere vernal equinox, is not quite fixed. A slow motion of Earth's axis, precession, causes a slow, continuous turning of the coordinate system westward about the poles of the ecliptic, completi ...

Mockingbird
Mockingbirds are a group of New World passerine birds from the family Mimidae. They are best known for the habit of some species mimicking the songs of other birds and the sounds of insects and amphibians, often loudly and in rapid succession. There are about 17 species in two genera, although three species of mockingbird from the Galapagos Islands were formerly separated into a third genus, ''Nesomimus''. The mockingbirds do not appear to form a monophyletic lineage, as ''Mimus'' and ''Melanotis'' are not each other's closest relatives; instead, ''Melanotis'' appears to be more closely related to the catbirds, while the closest living relatives of ''Mimus'' appear to be thrashers, such as the sage thrasher.Hunt, Jeffrey S.; Bermingham, Eldredge; & Ricklefs, Robert E.

Turdus Solitarius
Turdus Solitarius (Latin for ''solitary thrush'') was a constellation created by French astronomer Pierre Charles Le Monnier in 1776 from stars of Hydra's tail. It was named after the Rodrigues solitaire, an extinct flightless bird that was endemic to the island of Rodrigues East of Madagascar in the Indian Ocean. It was replaced by another constellation, Noctua (the Owl), in ''A Celestial Atlas'' (1822) by the British amateur astronomer Alexander Jamieson Alexander Jamieson (1782–1850) was a Scottish writer and schoolmaster, now best known as a rhetorician. He has been described as effectively a professional textbook writer. After the failure of his school, he worked as an actuary.

Turdus
True thrushes are medium-sized mostly insectivorous or omnivorous birds in the genus ''Turdus'' of the wider thrush family, Turdidae. The genus name ''Turdus'' is Latin for "thrush". The term " thrush" is used for many other birds of the family Turdidae as well as for a number of species belonging to several other families. The genus has a cosmopolitan distribution, with species in the Americas, Europe, Asia, Africa and Australia. Several species have also colonised some oceanic islands, and two species have been introduced to New Zealand. Some New World species are called ''robins'', the most well known of which is the American robin. Several species are migratory. While some species are often split out of ''Turdus'', the two small thrushes formerly separated in ''Platycichla'' by many authors have been restored to the present genus in recent years. Taxonomy and systematics The genus ''Turdus'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth editi ...

Rock Thrush
The rock thrushes, ''Monticola'', are a genus of chats, medium-sized mostly insectivorous or omnivorous songbirds. All are Old World birds, and most are associated with mountainous regions. Taxonomy The genus was erected by the German naturalist Friedrich Boie in 1822. ''Monticola'' is the Latin word for mountain-dweller or mountaineer. The genus was formerly included in the thrush family Turdidae. Molecular phylogenetic studies published in 2004 and 2010 showed that the species are more closely related to members of the Old World flycatcher family Muscicapidae. The genus contains the following species: * White-winged cliff chat, ''Monticola semirufus'' (formerly in ''Thamnolaea'') * Cape rock thrush, ''Monticola rupestris'' * Sentinel rock thrush, ''Monticola explorator'' * Short-toed rock thrush, ''Monticola brevipes'' * Miombo rock thrush, ''Monticola angolensis'' * Common rock thrush The common rock thrush (''Monticola saxatilis''), also known as rufous-tailed rock ...

Rodrigues Solitaire
The Rodrigues solitaire (''Pezophaps solitaria'') is an extinct flightless bird that was endemic to the island of Rodrigues, east of Madagascar in the Indian Ocean. Genetically within the family of pigeons and doves, it was most closely related to the also extinct dodo of the nearby island Mauritius, the two forming the subfamily Raphinae. The Nicobar pigeon is their closest living genetic relative. Rodrigues solitaires grew to the size of swans, and demonstrated pronounced sexual dimorphism. Males were much larger than females and measured up to in length and in weight, contrasting with and for females. Its plumage was grey and brown; the female was paler than the male. It had a black band at the base of its slightly hooked beak, and its neck and legs were long. Both sexes were highly territorial, with large bony knobs on their wings that were used in combat. The Rodrigues solitaire laid a single egg that was incubated in turn by both sexes. Gizzard stones helped digest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Charles Le Monnier
Pierre Charles Le Monnier (; 23 November 1715 – 3 April 1799) was a French astronomer. His name is sometimes given as Lemonnier. Biography Le Monnier was born in Paris, where his father Pierre (1675–1757), also an astronomer, was professor of philosophy at the college d'Harcourt. His first recorded astronomical observation was made before he was sixteen, and the presentation of an elaborate lunar map resulted in his admission to the French Academy of Sciences, on 21 April 1736, aged only 20. He was chosen in the same year to accompany Pierre Louis Maupertuis and Alexis Clairaut on their geodetical expedition for measuring a meridian arc of approximately one degree's length to Torne Valley in Lapland. In 1738, shortly after his return, he explained, in a memoir read before the Academy, the advantages of John Flamsteed's mode of determining right ascensions. His persistent recommendation of British methods and instruments contributed effectively to the reform of French p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Magnitude (astronomy)
In astronomy, magnitude is a unitless measure of the brightness Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, ... of an astronomical object, object in a defined passband, often in the visible spectrum, visible or infrared spectrum, but sometimes across all wavelengths. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus. The scale is Logarithmic scale, logarithmic and defined such that a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star. Thus each step of one magnitude is \sqrt[5] \approx 2.512 times brighter than the magnitude 1 higher. The brighter an object appears, the lower the value of its magnitude, with the brightest objects reaching negative values. Astronomers use two different defini ...

Urania's Mirror
''Urania's Mirror; or, a view of the Heavens'' is a set of 32 astronomical star chart cards, first published in November 1824. They are illustrations based on Alexander Jamieson's ''A Celestial Atlas'', but the addition of holes punched in them allow them to be held up to a light to see a depiction of the constellation's stars. See also :File:Advertisement for Urania's Mirror.png. They were engraved by Sidney Hall, and were said to be designed by "a lady", but have since been identified as the work of the Reverend Richard Rouse Bloxam, an assistant master at Rugby School. p239/ref> The cover of the box-set depicts Urania, the muse of astronomy. It originally came with a book entitled ''A Familiar Treatise on Astronomy...'' written as an accompaniment. Peter Hingley, the researcher who solved the mystery of who designed the cards a hundred and seventy years after their publication, considered them amongst the most attractive star chart cards of the many produced in the early 19th ...
