  • SN 1885A, ou SN 1885, est une supernova qui s'est produite dans la galaxie d'Andromède dont l'explosion a été observée sur Terre en 1885. Il s'agissait de la première supernova observée depuis l'invention du télescope.
  • S Andromedae (nota anche come SN 1885a) fu una supernova che esplose nella Galassia di Andromeda, l'unica osservata finora in quella galassia dagli astronomi, nonché la prima osservata in una galassia diversa dalla Via Lattea; è anche nota come "Supernova 1885".Fu scoperta il 20 agosto 1885 da Ernst Hartwig che lavorava al Dorpat Observatory in Estonia. Raggiunse al suo massimo una magnitudine apparente uguale a 6, al limite estremo della visibilità ad occhio nudo, per poi scendere al di sotto della magnitudine 16 già dal febbraio 1890.La stella fu segnalata come di colore tendente al rosso, e scese molto velocemente in luminosità, cosa atipica per una supernova; sfortunatamente non sono state effettuate rilevazioni spettroscopiche.Nel 1988 un team di astronomi capeggiati da R. A. Fesen, usando il telescopio di 4 metri Mayall a Kitt Peak, scoprirono il suo resto, ricco in ferro; Ulteriori osservazioni furono compiute nel 1995 dal Telescopio Spaziale Hubble.
  • S Andromedae (também conhecida como SN 1885A) foi uma supernova que ocorreu na Galáxia de Andrômeda, e que só vista nesta galáxia por astronômos, e a primeira identificada fora da Via Láctea. É também conhecida como a "Supernova de 1885".Ela foi descoberta em 20 de Agosto de 1885 por Ernst Hartwig, trabalhando no Observatório Dorpat (Tartu), na Estônia. Ela atingiu magnitude 6, e depois foi diminuindo para 16, em Fevereiro de 1890.A estrela a ser relatada era avermelhada em cor e muito declinada em brilho, típica de um supernova do tipo Ia. Infelizmente não forma feitas observações espectroscópicas.Em 1988, o astronômo R. A. Fesen e outros, usaram o Teslescópio Mayall, de qutro metors de abertura, e Kitt Peak descobriu o remanescente da explosão. Futuras observações foram feitas pelo Telescópio Espacial Hubble, em 1995.
  • S Andromedae (SN 1885) – supernowa typu Ia w galaktyce M31 w gwiazdozbiorze Andromedy. Zaobserwował ją 20 sierpnia 1885 Ernst Hartwig z Obserwatorium w Tartu w Estonii. Jest to pierwsza odkryta supernowa spoza naszej galaktyki.Między 17 a 20 sierpnia 1885 osiągnęła jasność ok. 5,8m. W lutym 1890 osłabła do 16m. Ponad sto lat później (10 listopada 1989) Robert A. Fesen odkrył jej pozostałości. Mają rozmiary rzędu 0,55 sekundy kątowej i masę pomiędzy 0,1 a 1 masy Słońca.S Andromedae jest jedyną do tej pory zaobserwowaną supernową w Galaktyce Andromedy.
  • S Андромеды, или SN 1885A — сверхновая звезда в галактике Андромеды, вспыхнувшая в 1885 году. Это единственная сверхновая, наблюдавшаяся в этой галактике, и первая из обнаруженных за пределами Млечного Пути.
  • SN 1885A (S Andromedae) was de eerste waargenomen extragalactische supernova, in de Andromedanevel (M31). Deze supernova werd op 19 augustus 1885 ontdekt door Isaac Ward, een Ierse amateurastronoom, in Belfast, en onafhankelijk van hem een dag later door Ernst Hartwig van de Sterrenwacht Dorpat (het huidige Tartu-observatorium) in Estland.Aanvankelijk dacht men dat het om een gewone nova ging die tussen 17 en 20 augustus bij zijn maximum een schijnbare helderheid van 5,85 bereikte. De reden was dat astronomen destijds ervan uit gingen dat de Andromedanevel tot de Melkwegstelsel behoorde. Deze zienswijze veranderde in 1923 toen Edwin Hubble ontdekte dat de nevel een ander sterrenstelsel was. In plaats van duizenden lichtjaar bedroeg de afstand meer dan een miljoen lichtjaar. Al snel realiseerde men dat de nova van 1885 iets speciaals moest zijn geweest: een Supernova.Een overblijfsel van SN 1885A werd op 10 november 1988 door Robert A. Fesen met de vier-meter Mayall Telescoop van het Kitt Peak National Observatory gevonden.
  • 안드로메다자리 S는 안드로메다 은하에서 발생하였던 초신성 폭발이다.우리 은하 외부에서 발생한 이 첫 초신성 폭발은 '1885 초신성 폭발' 으로 잘 알려져 있다.아일랜드의 아마추어 천문학자 Issac Ward에 의해 1885년 8월 19일 발견되었으며, 독립적으로 에스토니아의 Ernst Hartwig에 의해 발견되기도 하였다.초신성 폭발은 순간 적으로 겉보기 밝기 +6까지 밝기가 상승했으나 1886년 2월 1일에는 +16까지 어두워졌다.별은 희미한 적색을 띠었고 매우 급격히 광도를 잃어 버린 것으로 보고 되었다. 이러한 현상은 초신성 폭발 중에서도 매우 기이한 현상이었지만 불행하게도 분광(Spectrum) 기록을 찾을 수 없어서 수수께끼로 남아있다. 초신성 폭발이 발생한 위치는 안드로메다 은하 중심부에서 약 16초 정도 떨어진 곳 이었다. 이 때문에 초신성의 잔해를 파악하는데 매우 어려웠고 여러 번 관측을 시도하였지만 성공하지 못하였다.1988년 천문학자 R.A.Fesen와 동료들은 Kitt Peak에서 4미터 Mayll 망원경으로 철 함량이 풍부한 초신성 잔재를 발견하였고, 1995년에는 허블 망원경으로도 관측되었다.
  • La S Andromedae (también denominada SN 1885A) fue una supernova, visible desde la Tierra en 1885. La estrella pertenecía a la galaxia Messier 31 o Andrómeda. También se la conoció con el nombre "Supernova 1885". Es la única supernova vista en la galaxia de Andrómeda, desde que existen registros contrastables.Fue descubierta el 20 de agosto de 1885 por Ernst Hartwig, que trabaja en el observatorio Dorpat (Tartu), en Estonia. Esto alcanzó la magnitud 6, pero se debilitó hasta la magnitud 16 hacia febrero de 1890.
  • S Andromeda (també SN 1885A) fou una supernova a la galàxia d'Andròmeda, l'única vista en aquesta galàxia tan a lluny pels astrònoms, i la primera mai vista a fora la Via Làctia.Va ser descoberta el 20 d'agost de 1885 per Ernst Hartwig, que treballava al observatori de Dorpat (Tartu) a Estònia. Abastà la 6ena magnitud, però es va apagar de mica en mica fins a la 16ena magnitud el febrer de 1890.Es va relatar que l'estrella es tornà vermella de color i el seu esclat declinà molt ràpidament, la qual cosa és atípica per una supernova del tipus Ia. Malauradament no es disposa de dades espectroscòpiques.L'any 1988, l'astrònom R. A. Fesen i altres, usant el telescopi Mayall de 4 metres a Kitt Peak, descobrí el romanent de l'explosió ric en ferro.
  • SN 1885A (also S Andromedae) was a supernova in the Andromeda Galaxy, the only one seen in that galaxy so far by astronomers, and the first ever noted outside the Milky Way. It is also known as "Supernova 1885".It appears to have been seen first on August 17, 1885, by French astronomer Ludovic Gully during a public star gazing event, although Gully at that time thought it was scattered moonlight in his telescope and didnot follow up on this observation. Irish amateur astronomer Isaac Ward in Belfast claimed to have seen the object on August 19, 1885, but did not immediately publish its existence. The independent detection of the supernova by Ernst Hartwig at Dorpat (Tartu) Observatory in Estonia on August 20, 1885, however, was communicated in a telegram on August 31, 1885, once Hartwig hadverified in more ideal circumstances that the feature was not caused by reflected moonlight. The telegram prompted widespread observations of the event, and prompted Isaac Ward, Ludovic Gully, and several others to publish their earlier observations (the first reports on S And appeared before Hartwig's discovery letter which followed his telegram, since the letter was initially lost by Astronomische Nachrichten and only reprinted in a later issue). The history of the discovery is summarized by K.G. Jones and de Vaucouleurs and Corwin. Both studies doubt that Ward really saw the event since his estimated magnitude is significantly off from the later reconstructed lightcurve and conclude that Hartwig should be considered as the discoverer of the Supernova.SN 1885A reached magnitude 5.85 on 21 August 1885 and faded to magnitude 14 half a year later. The star was reported to be reddish in color and declined very rapidly in brightness, which is atypical for Type Ia supernovae. Some astronomers observed spectrum of the star visually (no photographic spectral observations were made in that times). These observations were made at the limit of visibility, but they are in good agreement with each other and with modern data on typical supernovae of Type Ia. It's a strong evidence for assignment of this star to this type.The location of the supernova event was 16″ from the relatively bright nucleus of the galaxy. This made detection of the supernova remnant difficult, and multiple attempts proved unsuccessful. Finally, in 1988, R. A. Fesen and others using the 4-meter Mayall telescope at Kitt Peak discovered the iron-rich remnant of the explosion. Further observations were made with the Hubble Space Telescope in 1999.The importance of observing the Andromeda S supernova is that, by comparing its magnitude to records of nearby supernovae, astronomers found it to be at least 750,000 light-years distant (later revised to 2,200,000); and that M31 was not a gas or dust cloud, but an "island universe" or galaxy[citation needed].
