NGC 7814

NGC 7814 è una galassia a spirale nella costellazione di Pegaso, alla distanza di 53 milioni di anni luce.
E' caratterizzata da una banda scura di polveri che la attraversa nel piano del disco: e questo è il tratto distintivo di questa galassia, anche perchè dato l'angolo di inclinazione con cui si mostra a noi, non è possibile avere ulteriori indizi su quale sia la sua struttura a spirale.
Il colore giallo diffuso attorno al nucleo è forse indizio di un basso processo di formazione stellare.
Da notare sulla sinistra di NGC 7814 due galassie molto deboli: potrebbero essere in effetti due galassie compagne.

----------

NGC 7814 is a spiral galaxy located in Pegasus constellation. Its distance from the Milky Way is 53 million light years and the angular size of 5.5’ x 2.3’ corresponds to a real diameter of 85000 light years.
The galaxy is seen almost edge-on and is featured by a dust lane in the plane of the disc: the high angle of inclination prevents one from saying anything about the spiral pattern of NGC 7814.
The diffuse yellow light from the bulge lends weight to the hypothesis that the current star formation rate of this galaxy is low.
Several other galaxies are visible in the image: to be noted two very faint galaxies on the left side of NGC 7814 which could be its satellite galaxies.
