Stephan s Quintet : The first identified compact galaxy group, Stephan's Quintet is featured in this eye-catching image constructed with data drawn from the extensive Hubble Legacy Archive. About 300 million light-years away, only four of these five galaxies are actually locked in a cosmic dance of repeated close encounters. The odd man out is easy to spot, though. The interacting galaxies, NGC 7319, 7318A, 7318B, and 7317 have an overall yellowish cast. They also tend to have distorted loops and tails, grown under the influence of disruptive gravitational tides. But the predominantly bluish galaxy, NGC 7320, is closer, just 40 million light-years distant, and isn't part of the interacting group. Stephan's Quintet lies within the boundaries of the high flying constellation Pegasus. At the estimated distance of the quartet of interacting galaxies, this field of view spans about 500,000 light-years. But moving just beyond this field, up and to the right, astronomers can identify another galaxy, NGC 7320C, that is also 300 million light-years distant. Including it would bring the interacting quartet back up to quintet status. via NASA

Stephan’ın Beşlisi

Günün Astronomi Görseli 18 Aralık 2021

Görsel & Telif: NASA, ESA, Hubble Legacy Archive; Görüntü İşleme & Telif: Bernard Miller

Belirlenmiş ilk kompakt galaksi grubu, Stephan’ın Beşlisi, geniş Hubble Mirası Arşivi‘nden alınan verilerle oluşturulan bu göz alıcı görselde gösteriliyor. Yaklaşık 300 milyon ışık yılı mesafede, bu galaksilerden yalnızca dört tanesi gerçekte tekrarlayan yakın temasların bir kozmik dansında hapsolmuş durumdalar. Burada dışlanmış olansa kolayca seçilebiliyor. Etkileşen galaksiler NGC 7319, 7318A, 7318B ve 7317, genel olarak sarımsı bir tona sahipler. Aynı zamanda, bozucu kütle çekim akımlarının etkisi altında oluşmuş, bozulmuş düğümler ve kuyruklara sahip olma eğilimi gösteriyorlar. Ama baskın olarak mavimsi galaksi NGC 7320 daha yakında, sadece 40 milyon ışık yılı mesafede ve etkileşen grubun bir parçası değil. Stephan’ın Beşlisi takım yıldız Kanatlı At‘ın (Pegasus) sınırları içinde yer alıyor. Etkileşen galaksiler beşlisinin tahmini mesafesinde, bu görüş alanı 500 bin ışık yılı boyunca uzanıyor. Ama bu alanın hemen dışına çıkıldığında, sağ üste doğru, astronomlar bir başka galaksiyi, yine 300 milyon ışık yılı uzaklıktaki NGC 7320C’yi belirleyebiliyorlar. Bu da dahil edilirse, etkileşen beşli artık altılı durumuna gelmeli.

STEPHAN'S QUINTET Stephan's Quintet is the first compact galaxy group ever discovered. Three hundred million light years away in the Pegasus constellation, four of the five galaxies interact in a violent cosmic collision. The outlier is easy to spot--at 40 million light years away, NGC 7320's bluish tint indicates a lower redshift, and thus a smaller distance.

The yellowish interacting galaxies, (left-right) NGC 7319, 7318B, 7318A, and 7317, possess warped tails and elongated arms that are a result of the gravitational tides. As NGC 731B moves toward the center of the group at 1000 km/second, it collides with gas that lies in the intergalactic space. Much like a massive-scale sonic boom, this collision produces a shock wave that is bigger than our own Milky Way. This shock wave produces a turbulent emission of molecular hydrogen that was detected by the Spitzer Space Telescope using infrared spectral analysis. (The emission can be seen here as a glowing green arc between the galaxies: http://bit.ly/TYRV8z) The fragility of the hydrogen molecule made this discovery unexpected--normally it would be destroyed in this type of shock wave. One hypothesis that a series of smaller shock waves travel in the larger one's wake, allowing the molecular hydrogen to survive. Studying this powerful emission may provide clues about the beginning of the Universe, since it is believed that shocked molecular hydrogen existed in its early formation when galactic mergers were very common. -RLO Image credit: Hubble Legacy Archive, ESA, NASA; Processing: Al Kelly Sources: http://www.spitzer.caltech.edu/images/1605-ssc2006-08a-A-Shocking-Surprise-in-Stephan-s-Quintet http://phys.org/news11392.html

Stephan's Quintet from Hubble

When did these big galaxies first begin to dance? Really only four of the five ofStephan's Quintet are locked in a cosmic tango of repeated close encounters taking place some 300 million light-years away. The odd galaxy out is easy to spot in this recently reprocessed image by the Hubble Space Telescope -- the interacting galaxies, NGC 7319, 7318B, 7318A, and 7317 (left to right), have a more dominant yellowish cast. They also tend to have distorted loops and tails, grown under the influence of disruptive gravitational tides. The mostly bluish galaxy, large NGC 7320 on the lower left, is in the foreground at about 40 million light-years distant, and so is not part of theinteracting group. Data and modeling indicate that NGC 7318B is a relatively new intruder. A recently-discovered haloof old red stars surrounding Stephan's Quintet indicate that at least some of these galaxies started tangling over a billion years. Stephan's Quintet is visible with a moderate sized-telescope toward the constellation of Winged Horse (Pegasus).

IMMAGINI DAL TELESCOPIO WEBB. CINQUE GALASSIE http://www.impresaoggi.com/it2/2408-con_le_immagini_del_webb_ci_si_avvicina_allalba_delluniverso/ È un gruppo di cinque galassie a 290 milioni di anni luce nella costellazione di Pegaso. Il Quintetto di Stephan è formato da quattro galassie situate vicino fisicamente e da un’altra galassia, NGC 7320, la più luminosa del gruppo, che appartiene al gruppo solo dal nostro punto di osservazione. Le quattro galassie vicine fisicamente (NGC 7317, NGC 7318A, NGC 7318B e NGC 7319) distano da noi di circa 290 milioni di anni luce. La quinta galassia invece è distante da noi 40 milioni di anni luce. https://www.instagram.com/p/CmWfAM6j2ZI/?igshid=NGJjMDIxMWI=

El quinteto de Stephan

Webb arroja luz sobre la evolución de las galaxias y los agujeros negros

El quinteto de Stephan, una agrupación visual de cinco galaxias.

Con su poderosa visión infrarroja y su resolución espacial extremadamente alta, Webb muestra detalles nunca antes vistos en este grupo de galaxias. Cúmulos brillantes de millones de estrellas jóvenes y regiones de brotes estelares de nacimiento de estrellas frescas adornan la imagen. Las colas de barrido de gas, polvo y estrellas están siendo extraídas de varias de las galaxias debido a las interacciones gravitatorias. Más dramáticamente, Webb captura enormes ondas de choque cuando una de las galaxias, NGC 7318B, atraviesa el cúmulo.

Juntas, las cinco galaxias del Quinteto de Stephan también se conocen como Hickson Compact Group 92 (HCG 92). Aunque se llama un "quinteto", solo cuatro de las galaxias están realmente juntas y atrapadas en una danza cósmica. La quinta y más a la izquierda, llamada NGC 7320, está en primer plano en comparación con las otras cuatro. NGC 7320 reside a 40 millones de años luz de la Tierra, mientras que las otras cuatro galaxias (NGC 7317, NGC 7318A, NGC 7318B y NGC 7319) están a unos 290 millones de años luz de distancia. Esto todavía está bastante cerca en términos cósmicos, en comparación con galaxias más distantes a miles de millones de años luz de distancia. Estudiar galaxias relativamente cercanas como estas ayuda a los científicos a comprender mejor las estructuras que se ven en un universo mucho más distante.
