Fornax (constellation)
Fornax () is a constellation in the southern celestial hemisphere, partly ringed by the celestial river Eridanus. Its name is Latin for furnace. It was named by French astronomer Nicolas Louis de Lacaille in 1756. Fornax is one of the 88 modern constellations. The three brightest stars—Alpha, Beta and Nu Fornacis—form a flattened triangle facing south. With an apparent magnitude of 3.91, Alpha Fornacis is the brightest star in Fornax. Six star systems have been found to have exoplanets. The Fornax Dwarf galaxy is a small faint satellite galaxy of the Milky Way. NGC 1316 is a relatively close radio galaxy. It is the 41st largest constellation in the night-sky, occupying an area of 398 square degrees. It is located in the first quadrant of the southern hemisphere (SQ1) and can be seen at latitudes between +50° and -90° during the month of December. History The French astronomer Nicolas Louis de Lacaille first described the constellation in French as ''le Fourneau Chy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazier
A brazier () is a container used to burn charcoal or other solid fuel for cooking, heating or cultural rituals. It often takes the form of a metal box or bowl with feet. Its elevation helps circulate air, feeding oxygen to the fire. Braziers have been used since ancient times; the Nimrud brazier dates to at least 824 BC. History The word brazier is mentioned in the Bible. The Hebrew word for brazier is believed to be of Egyptian origin, suggesting that it was imported from Egypt. The lone reference to it in the Bible being the following verse: * - the winter palace of King Jehoiakim was heated by a brazier (). Roman Emperor Jovian was poisoned by the fumes from a brazier in his tent in 364, ending the line of Constantine. Uses Heating Despite risks in burning charcoal on open fires, braziers were widely adopted for domestic heating, particularly and somewhat more safely used (namely in unglazed, shuttered-only buildings) in the Spanish-speaking world.

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 ...

Table Mountain
Table Mountain ( naq, Huriǂoaxa, lit= sea-emerging; af, Tafelberg) is a flat-topped mountain forming a prominent landmark overlooking the city of Cape Town in South Africa. It is a significant tourist attraction, with many visitors using the cableway or hiking to the top. Table Mountain National Park is the most visited national park in South Africa, attracting 4.2 million people every year for various activities. The mountain has 8,200 plant species, of which around 80% are fynbos, meaning fine bush. It forms part of the Table Mountain National Park, and part of the lands formerly ranged by Khoe-speaking clans, such as the (the "High Clan"). It is home to a large array of mostly endemic fauna and flora. Features The main feature of Table Mountain is the level plateau approximately from side to side, edged by steep cliffs. The plateau, flanked by Devil's Peak to the east and by Lion's Head to the west, forms a dramatic backdrop to Cape Town. This broad sweep of mount ...

Mensa (constellation)
Mensa is a constellation in the Southern Celestial Hemisphere near the south celestial pole, one of fourteen constellations drawn up in the 18th century by French astronomer Nicolas-Louis de Lacaille. Its name is Latin for table, though it originally commemorated Table Mountain and was known as "Mons Mensae". One of the eighty-eight constellations designated by the International Astronomical Union (IAU), it covers a keystone-shaped wedge of sky 153.5 square degrees in area. Other than the south polar constellation of Octans, it is the most southerly of constellations and is observable only south of the 5th parallel of the Northern Hemisphere. One of the faintest constellations in the night sky, Mensa contains no apparently bright stars—the brightest, Alpha Mensae, is barely visible in suburban skies. Part of the Large Magellanic Cloud, several star clusters and a quasar lie in the area covered by the constellation, and at least three of its star systems have been f ...

Age Of Enlightenment
The Age of Enlightenment or the Enlightenment; german: Aufklärung, "Enlightenment"; it, L'Illuminismo, "Enlightenment"; pl, Oświecenie, "Enlightenment"; pt, Iluminismo, "Enlightenment"; es, La Ilustración, "Enlightenment" was an intellectual and philosophical movement that dominated Europe in the 17th and 18th centuries with global influences and effects. The Enlightenment included a range of ideas centered on the value of human happiness, the pursuit of knowledge obtained by means of reason and the evidence of the senses, and ideals such as liberty, progress, toleration, fraternity, and constitutional government. The Enlightenment was preceded by the Scientific Revolution and the work of Francis Bacon, John Locke, and others. Some date the beginning of the Enlightenment to the publication of René Descartes' ''Discourse on the Method'' in 1637, featuring his famous dictum, ''Cogito, ergo sum'' ("I think, therefore I am"). Others cite the publication of Isaac Newto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Celestial Hemisphere
The southern celestial hemisphere, also called the Southern Sky, is the southern half of the celestial sphere; that is, it lies south of the celestial equator. This arbitrary sphere, on which seemingly fixed stars form constellations, appears to rotate westward around a polar axis due to Earth's rotation. At any given time, the entire Southern Sky is visible from the geographic South Pole, while less of this hemisphere is visible the further north the observer is located. The northern counterpart is the northern celestial hemisphere. Astronomy In the context of astronomical discussions or writing about celestial mapping, it may also simply then be referred to as the Southern Hemisphere. For the purpose of celestial mapping, the sky is considered by astronomers as the inside of a sphere divided in two halves by the celestial equator. The Southern Sky or Southern Hemisphere is, therefore, that half of the celestial sphere that is south of the celestial equator. Even if ...

Cape Of Good Hope
The Cape of Good Hope ( af, Kaap die Goeie Hoop ) ;''Kaap'' in isolation: pt, Cabo da Boa Esperança is a rocky headland on the Atlantic coast of the Cape Peninsula in South Africa. A common misconception is that the Cape of Good Hope is the southern tip of Africa, based on the misbelief that the Cape was the dividing point between the Atlantic and Indian oceans, and have nothing to do with north or south. In fact, by looking at a map, the southernmost point of Africa is Cape Agulhas about to the east-southeast. The currents of the two oceans meet at the point where the warm-water Agulhas current meets the cold-water Benguela current and turns back on itself. That oceanic meeting point fluctuates between Cape Agulhas and Cape Point (about east of the Cape of Good Hope). When following the western side of the African coastline from the equator, however, the Cape of Good Hope marks the point where a ship begins to travel more eastward than southward. Thus, the first mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alembic
An alembic (from ar, الإنبيق, al-inbīq, originating from grc, ἄμβιξ, ambix, 'cup, beaker') is an alchemical still consisting of two vessels connected by a tube, used for distillation of liquids. Description The complete distilling apparatus consists of three parts: the "cucurbit" (Arabic: ; Greek: , ), the still pot containing the liquid to be distilled, which is heated by a flame; the "head" or "cap" (, ; Greek , ) which fits over the mouth of the cucurbit to receive the vapors, with an attached downward-sloping "tube" (, ); and the "receiver" (, ; , or , ) container. In the case of another distilling vessel, the retort, the "cap" and the "cucurbit" have been combined to form a single vessel. The anbik is also called the raʾs (head) of the cucurbit. The liquid in the cucurbit is heated or boiled; the vapour rises into the anbik, where it cools by contact with the walls and condenses, running down the spout into the receiver. A modern descendant of the alemb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocean ...

Square Degree
__NOTOC__ A square degree (deg2) is a non- SI unit measure of solid angle. Other denotations include ''sq. deg.'' and (°)2. Just as degrees are used to measure parts of a circle, square degrees are used to measure parts of a sphere. Analogous to one degree being equal to radians, a square degree is equal to ()2 steradians (sr), or about sr or about . The whole sphere has a solid angle of which is approximately : : 4 \pi \left(\frac\right)^2 \, ^2 = \frac\,\, ^2 = \frac \,\, ^2 \approx 41\,252.96 \,\, ^2 Examples * The full moon covers only about of the sky when viewed from the surface of the Earth. The Moon is only a half degree across (i.e. a circular diameter of roughly ), so the moon's disk covers a circular area of: ()2, or 0.2 square degrees. The moon varies from 0.188 to depending on its distance to the Earth. * Viewed from Earth, the Sun is roughly half a degree across (the same as the full moon) and covers only as well. * It would take times the full ...
