Barred Spiral

A lot of galaxies have this structure rather than the cloud or continuous spiral shape. This is NGC 1300 in a new composite Hubble photo. Cool to see the regular spiral details in the center. I didn't know about that before. The scientists tell us that there is no massive black hole at the center of this big galaxy, at least none detected yet. Hmm.
Does that have anything to do with the structure?

NGC 1300 is classified SB(s)bc which means, I think, that the spiral arms are about mid-range tight. (The classification a is very tight and d is very loose, putting two letters means the tightness is halfway between the two letters).


This is a very beautiful and interesting research
The most educating one i have read today!
