Image caption:
This image from the Hubble Space Telescope shows the barred spiral galaxy UGC 6093. This galaxy has two spiral arms in its outer regions but the inner edge of each arm joins with the outer edge of a straight bar feature that goes across the galaxy's center.
This galaxy has been classified as an active galaxy due to the emissions of certain lines in its spectrum. This indicates that the supermassive black hole that lies in the center of the galaxy is accreting gas from its surroundings. Unlike some active galactic nuclei (AGN), the center of this galaxy does not shine especially brightly in the visible light so its status as an AGN is not immediately visible from this image.

Image caption: Questa immagine del telescopio spaziale Hubble mostra la galassia a spirale barrata UGC 6093. Questa galassia presenta due bracci a spirale nelle sue regioni esterne, ma il bordo interno di ciascun braccio si unisce al bordo esterno di una barra diritta che attraversa il centro della galassia.
Questa galassia è stata classificata come galassia attiva a causa delle emissioni di determinate righe nel suo spettro. Ciò indica che il buco nero supermassiccio situato al centro della galassia sta accumulando gas dall’ambiente circostante. A differenza di alcuni nuclei galattici attivi (AGN), il centro di questa galassia non brilla in modo particolarmente intenso nella luce visibile, pertanto la sua natura di AGN non è immediatamente riconoscibile da questa immagine.
