Ægir
Ægir (anglicised as Aegir; Old Norse 'sea'), Hlér (Old Norse 'sea'), or Gymir (Old Norse less clearly 'sea, engulfer'), is a jötunn and a personification of the sea in Norse mythology. In the Old Norse record, Ægir hosts the gods in his halls and is associated with brewing ale. Ægir is attested as married to a goddess, Rán, who also personifies the sea, and together the two produced daughters who personify waves, the Nine Daughters of Ægir and Rán, and Ægir's son is Snær, personified snow. Ægir may also be the father of the beautiful jötunn Gerðr, wife of the god Freyr, or these may be two separate figures who share the same name (see below and Gymir (father of Gerðr)). One of Ægir's names, ''Hlér'', is the namesake of the island Læsø (Old Norse ''Hléysey'' 'Hlér's island') and perhaps also Lejre in Denmark. Scholars have long analyzed Ægir's role in the Old Norse corpus, and the concept of the figure has had some influence in modern popular culture. Names ...

Aegir (moon)
Aegir, also Saturn XXXVI (provisional designation S/2004 S 10), is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on May 4, 2005, from observations taken between December 12, 2004, and March 11, 2005. Aegir is about 6 kilometres in diameter, and orbits Saturn at an average distance of 19,618 Mm in 1025.908 days, at an inclination of 167° to the ecliptic (140° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.237. Name The moon was named in April 2007 after Ægir, a giant from Norse mythology, the personification of tranquil seas, the one who soothes storms away. He is a son of Fornjót, and brother of Logi (fire, flame) and Kári (wind). The exoplanet Epsilon Eridani b (AEgir) was also named after this figure in 2015. The name may be pronounced various ways. (with the 'g' pronounced as a ''y''-sound) approximates modern Norwegian and Icelandic. (with a hard 'g') ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AEgir (planet)
Epsilon Eridani b, also known as AEgir ,There is some question on whether the name should be spelled (with an æ ligature), but the official press release from the IAU has . is an exoplanet approximately 10.5 light-years away orbiting the star Epsilon Eridani, in the constellation of Eridanus (the River). The planet was discovered in 2000, and as of 2022 remains the only confirmed planet in its planetary system. It orbits at around 3.5 AU with a period of around 7.6 years, and has a mass around 0.6 times that of Jupiter. , both the Extrasolar Planets Encyclopaedia and the NASA Exoplanet Archive list the planet as 'confirmed'. Name The planet and its host star are one of the planetary systems selected by the International Astronomical Union as part of NameExoWorlds, their public process for giving proper names to exoplanets and their host star (where no proper name already exists). The process involved public nomination and voting for the new names. In December 2015, the IAU ann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trent Aegir
The Trent Aegir, also known as the Eagre, is a tidal bore on the River Trent in England. At certain times of the year, the lower tidal reaches of the Trent experience a moderately large bore (up to five feet (1.5m) high). It is said to take its name from Ægir, a personification of the sea in Norse mythology,Richard Stone, ''The River Trent'', (2005), p9, p124, Phillimore & Co Ltd, although this is disputed. A more likely derivation is from Old English ''ēagor'' (“flood, stream, water”). The Aegir occurs when a high spring tide meets the downstream flow of the river. The funnel shape of the river mouth exaggerates this effect, causing a large wave to travel upstream as far as Gainsborough, Lincolnshire, and sometimes beyond. The Aegir cannot travel much beyond Gainsborough as the shape of the river reduces the Aegir to little more than a ripple, and weirs north of Newark-on-Trent, Nottinghamshire stop its path completely. The Aegir can be seen at Gainsborough, Morton, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aegir Ridge
The Aegir Ridge is an extinct segment of the Mid-Atlantic Ridge in the far-northern Atlantic Ocean. It marks the initial break-up boundary between Greenland and Norway, along which seafloor spreading was initiated at the beginning of the Eocene Epoch (geology), epoch to form the northern Atlantic Ocean. Towards the end of the Eocene, the newly forming Kolbeinsey Ridge propagated northwards from Iceland, splitting the Jan Mayen Microcontinent away from the Greenland Plate. As the Kolbeinsey Ridge formed, so activity on the Aegir Ridge reduced, ceasing completely at the end of the Oligocene epoch when the Kolbeinsey Ridge reached the Jan Mayen Fracture Zone. The relatively thin crust and short lifespan of the Aegir Ridge is anomalous given its proximity to the Iceland hotspot. Mantle Hotspot (geology), hotspots deliver warm, actively-upwelling material to mid-ocean ridges, increasing mantle melting and crustal production. Likely, the stresses associated with plate tectonics and the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aegirine
Aegirine is a member of the clino pyroxene group of inosilicate minerals. Aegirine is the sodium endmember of the aegirine- augite series. Aegirine has the chemical formula Na Fe Si2 O6 in which the iron is present as Fe3+. In the aegirine-augite series the sodium is variably replaced by calcium with iron(II) and magnesium replacing the iron(III) to balance the charge. Aluminium also substitutes for the iron(III). Acmite is a fibrous, green-colored variety. Aegirine occurs as dark green monoclinic prismatic crystals. It has a glassy luster and perfect cleavage. Its Mohs hardness varies from 5 to 6, and its specific gravity is between 3.2 and 3.4. This mineral commonly occurs in alkalic igneous rocks, nepheline syenites, carbonatites and pegmatites. It also appears in regionally metamorphosed schists, gneisses, and iron formations; in blueschist facies rocks, and from sodium metasomatism in granulites. It may occur as an authigenic mineral in shales and marls. It occurs in ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ægir-class Offshore Patrol Vessel
The ''Ægir''-class offshore patrol vessel is a class of two offshore patrol vessels serving in the Icelandic Coast Guard (ICG). They participated in the two later Cod Wars. The vessels conduct patrols, search and rescue, fishery inspections, general law enforcement and counter-terrorism operations in the Icelandic exclusive economic zone and the waters of the surrounding territories, such as Greenland and Jan Mayen. Design and description The concept for the ''Ægir''-class OPV was based on the Icelandic Coast Guard experiences with ICGV ''Þór'' and . Rear Admiral Pétur Sigurðsson, commander of the ICG, set forth a requirement for a ship larger than both ''Þór'' and ''Óðinn'' and more seaworthy. The vessels were also armoured for icebreaking. Though of roughly the same design, the two ships are of different measurements. ''Ægir'' has a standard displacement of and at full load. The ship measures long with a beam of and a draught of .
