Summary

Description
Česky: NGC 1300, spirální galaxie s příčkou vyfotografována z Hubbleova vesmírného dalekohledu.
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 centre 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.

The image was constructed from exposures taken in September 2004 by the Advanced Camera for Surveys onboard Hubble in four filters. Starlight and dust are seen in blue, visible, and infrared light. Bright star clusters are highlighted in red by their associated emission from glowing hydrogen gas. Due to the galaxy's large size, two adjacent pointings of the telescope were necessary to cover the extent of the spiral arms. The galaxy lies roughly 69 million light-years away (21 megaparsecs) in the direction of the constellation Eridanus.

NGC 1300, située à 69 millions d'années lumière de nous dans la constellation d'Éridan, fait partie de ces galaxies possédans 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 nourissent 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.

La lumière des étoiles et de la poussière est visible en bleu. Celle des amas stellaires est soulignée par le rouge de l'hydrogène. Cette image est issue de l'assemblage de deux clichés pris par la caméra ACS.
