English: Barred spiral galaxy NGC 1300 photographed by Hubble telescope.
In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years (1 kiloparsec) long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black hole. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter. Español: NGC 1300, una galaxia espiral barrada.

NGC 1300, située à 69 millions d'années lumière de nous dans la constellation d'Éridan, fait partie de ces galaxies possédants une grande barre centrale. Cette barre contient une spirale de 3 300 années lumières de diamètre. Les gaz de la galaxie sont attirés vers l'intérieur de la barre puis dans la spirale interne de laquelle ils nourrissent un trou noir. Cependant, le centre de la galaxie n'est pas actif, ce qui laisse à penser que le trou noir central n'accrète pas de matière actuellement. Nederlands: NGC 1300, voorbeeld van een balkspiraal.
