betelgeuse mythology

Mythology and culture Like other exceptionally bright stars, Betelgeuse is part of the folklore and history of many different cultures. Of the lesser stars, Meissa (or Lambda Orionis) forms Orion's head, whilst Hatsya (or Iota Orionis) forms the tip of Orion's sword. [92] However, later evaluation of the Hipparcos parallax measurements for variable stars like Betelgeuse found that the uncertainty of these measurements had been underestimated. In the intermediate period (June–July), it is invisible to the naked eye (visible only with a telescope in daylight), except around midday in Antarctic regions between 70° and 80° south latitude (during polar night, when the Sun is below the horizon). What did the Egyptians think of Cleopatra? Some of these elements are known to be asymmetric while others overlap.[87]. It generally glows at magnitude +0.5, but is now at +1.5. It has no other choice in physics. More recently, Orion women have been seen in the films Star Trek and Star Trek Into Darkness. (7) Ibid., p. At near-infrared wavelengths, Betelgeuse is the brightest star in the night sky. (9) For more about Milky Way names in Irish, see: (10) McCionnaith, L., Foclóir Béarla agus Gaedhilge, 1935, p. 824. [169] In the popular science fiction series The Hitchhiker's Guide to the Galaxy by Douglas Adams, Ford Prefect was from "a small planet somewhere in the vicinity of Betelgeuse. The regular fluctuations in the brightness of Betelgeuse would undoubtedly have been noticed by the ancient astronomers. The star is known to fluctuate, in short cycles of 14 months and longer cycles lasting about six years, according to the New York Times. The Sun's heliopause is estimated at about 100 AU, so the size of this outer shell would be almost fourteen times the size of the Solar System. The map reveals vital details for getting a complete understanding of the dust and gas involved in star formation. He asks them to allow him to remain for a further seven years, which they agree to. It is now so entered in the IAU Catalog of Star Names. [104] For example, a measured angular diameter of 55.6 mas would correspond to a Rosseland mean diameter of 56.2 mas, while further corrections for the existence of surrounding dust and gas shells would give a diameter of 41.9 mas. (6) Ó hÓgáin, Dáithí (2006), The Lore of Ireland: An Encyclopaedia of Myth, Legend and Romance, The Collins Press, p. 385. 2 below, American Association of Variable Star Observers, "An Updated 2017 Astrometric Solution for Betelgeuse", "Modeling the Variable Chromosphere of α Orionis", "Bulletin of the IAU Working Group on Star Names, No. Bealach na Bó Fhinne (Way of the White Cow) and Bóthar na Bó Finne (Road of the White Cow) are two old Irish names for the Milky Way.(10). In 1993, the Hubble Space Telescope first observed the Orion Nebula. [28], Betelgeuse has a B–V color index of 1.85—a figure which points to its pronounced "redness". It was named after Orion, a hunter in Greek mythology. Although unexpected, it turns out to be the most abundant constituent of Betelgeuse's atmosphere. Orion is also important in Australian Aboriginal Astronomy. Females of the species have become known as Orion slave girls, who have become popular among fans for cosplay. See also Murphy, Anthony and Moore, Richard (2006), Island of the Setting Sun: In Search of Ireland’s Ancient Astronomers, Liffey Press, p. 231. This triggers reactions that can affect star formation, including the transformation of carbon monoxide molecules into carbon atoms and ions, called ionization. "), and Amos 5:8 ("He who made the Pleiades and Orion"). “Although the Tuatha Dé Danann attempt to keep Lug from the battle for his protection, he escapes to join the fighting, encouraging his host with chanted spells; and at a turning point in the conflict, he faces his maternal grandfather in single combat, destroying Balor by casting a sling-stone at his evil eye, and thereby avenging the fallen Núadu.”(5), There are several aspects of the story of Núadu that make him an interesting candidate, in my view, for the constellation we know today as Orion. The recent fluctuation and fading in the brightness of the star Betelgeuse in Orion prompted me to have a look at ancient Irish myths which might pertain to this constellation and its bright red star. It is interesting too that Núadu yields the throne to Lug (also spelt Lugh), who is pivotal to the success of the TDD in the Second Battle of Moytura. [32], In the 1970s, astronomers saw some major advances in astronomical imaging technology, beginning with Antoine Labeyrie's invention of speckle interferometry, a process that significantly reduced the blurring effect caused by astronomical seeing. [89] As the researcher, Harper, points out: "The revised Hipparcos parallax leads to a larger distance (152±20 pc) than the original; however, the astrometric solution still requires a significant cosmic noise of 2.4 mas. When it explodes it will even be visible during the day. Also included is a column providing a current range of radii for each study based on Betelgeuse's most recent distance estimate (Harper et al.) 824.

[146][147] The shock is not created by the star, but by its powerful stellar wind as it ejects vast amounts of gas into the interstellar medium at a speed of 17 km/s, heating the material surrounding the star, thereby making it visible in infrared light. Other names for Betelgeuse included the Persian Bašn "the Arm", and Coptic Klaria "an Armlet". Betelgeuse is a pulsating star, so its diameter changes with time; The star has no definable "edge" as limb darkening causes the optical emissions to vary in color and decrease the farther one extends out from the center; Betelgeuse is surrounded by a circumstellar envelope composed of matter ejected from the star—matter which absorbs and emits light—making it difficult to define the photosphere of the star; This page was last edited on 20 October 2020, at 04:48. Black hole makes 'String of Pearls' clusters   PhysOrg - April 1, 2014 Published from its offices at 200 Renfield Street Glasgow and printed in Scotland by Newsquest (Herald & Times) a division of Newsquest Media Group Ltd, registered in England & Wales with number 01676637 at Loudwater Mill, Station Road, High Wycombe HP10 9TY – a Gannett company. The translation of Cath Maige Tuired (The Second Battle of Mag Tuired), from the text of a 16th century vellum manuscript which is based on Old Irish materials, says: Now Núadu was being treated, and Dian Cécht put a silver hand on him which had the movement of any other hand.(2). Messiah on Temple Mount: Are We Nearing the End of Time? Two were drowned but Lug alone survived. The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. (4) Ibid. (9) For more about Milky Way names in Irish, see: https://blog.mythicalireland.com/2016/10/the-milky-way-in-irish-mythology-and_10.html(10) McCionnaith, L., Foclóir Béarla agus Gaedhilge, 1935, p. [152], The current mass can be estimated from evolutionary models from the initial mass and the expected mass lost so far. Hubble captured signs of dense, heated material moving through the star's atmosphere in September, October, and November" before multiple telescopes observing the more marked dimming in December and the first several months of 2020. Probably not, but astronomers are having fun thinking about it. Bellatrix was designated Gamma Orionis by Johann Bayer, but is known colloquially as the "Amazon Star". [97] Interferometric observations of Betelgeuse have shown hotspots that are thought to be created by massive convection cells, a significant fraction of the diameter of the star and each emitting 5–10% of the total light of the star. The term most likely comes from the fact it can be seen in the sky in early autumn in the Northern Hemisphere, the time of haymaking. [158][159] Betelgeuse is not likely to produce a gamma-ray burst and is not close enough for its x-rays, ultraviolet radiation, or ejected material to cause significant effects on Earth. [35][50][101] Combining these data with historical distance estimates of 180 to 815 ly yields a projected radius of the stellar disk of anywhere from 1.2 to 8.9 AU. Videos featuring Anthony Murphy/Mythical Ireland or relating to the many diverse topics explored on the website. In 1997, significant changes in the dust shell's morphology in one year were noted, suggesting that the shell is asymmetrically illuminated by a stellar radiation field strongly affected by the existence of photospheric hotspots. [30], The opposed locations of Orion and Scorpius, with their corresponding bright red variable stars Betelgeuse and Antares, were noted by ancient cultures around the world.

In Siberia, the Chukchi people see Orion as a hunter; an arrow he has shot is represented by Aldebaran (Alpha Tauri), with the same figure as other Western depictions. Bellatrix's luminosity is derived from its high temperature rather than its radius, a factor that defines Betelgeuse. Betelgeuse is often mistranslated as "armpit of the central one".

Subsequent studies have reported an angular diameter (i.e., apparent size) ranging from 0.042 to 0.056 arcseconds; that range of determinations is ascribed to non-sphericity, limb darkening, pulsations and varying appearance at different wavelengths. Betelgeuse's weird dimming caused by gigantic starspots. The Rig Veda refers to the Orion Constellation as Mriga (The Deer). Information and posts about Anthony Murphy's books. The constellation is mentioned in Horace's Odes (Ode 3.27.18), Homer's Odyssey (Book 5, line 283) and Iliad, and Virgil's Aeneid (Book 1, line 535). Michael McDowell, one of the writers of the 1988 madcap comedy horror movie directed by Tim Burton, said the star’s name inspired the character played by Michael Keaton. "[189], Two American navy ships were named after the star, both of them World War II vessels, the USS Betelgeuse (AKA-11) launched in 1939 and USS Betelgeuse (AK-260) launched in 1944. The star was named Beldengeuze in the Alfonsine Tables,[172] and Italian Jesuit priest and astronomer Giovanni Battista Riccioli had called it Bectelgeuze or Bedalgeuze. The Galactic Center takes us to the Holographic Universe or Simulation Theory. - A familiar star in the constellation Orion has dimmed noticeably since October. These composition anomalies are likely caused by contamination by CNO-processed material from the inside of Betelgeuse. It is the second brightest star in Orion, and is a semiregular variable star. [124], Betelgeuse has no known orbital companions, so its mass cannot be calculated by that direct method. Scholars in fact no longer talk of the Christian West when they speak of Modern Europe and North America, but of the Secular West. [84][85] Further studies have found no evidence for these companions or have actively refuted their existence,[86] but the possibility of a close companion contributing to the overall flux has never been fully ruled out.
