Barred spiral NGC 1300, does have SMBH! (APOD 27 Aug 2006)
Hi - Your 8-27-06 APOD says NGC 1300 has NO central supermassive
black hole. However, a search at the Harvard ADS site shows that
in May, 2005 a group found evidence for one weighing in at several
10^7 solar masses.

Barred Spiral 'Island Universe' NGC 1300 (APOD 27 Aug 2006)
Hi! I'm a long time fan of APOD (I have a folder of nearly 6 years of pics!), but this is my first post on this forum.
I think I was inspired to post by all the recent hullabaloo over nomenclature at the IAU; likely a hot topic!
The APOD for 26/8/06 (which is a beautiful pic, by the way!) refers to NGC1300 as an 'island universe'. I am aware of the term; my dad has an encyclopaedia from the 1940's that has some wonderful hand-painted illustrations of 'island universes'.
Surely the term is an anachronism nowdays? After all, we don't refer to 'busses' as 'motor-charabancs', or 'cars' as 'horseless carriages' unless we are trying to be anachronistic, obscure or both!
If we can keep refering to galaxies as 'island universes', can we also please keep refering to Ceres and Juno as 'planets' as they were originally described?
I expect an IAU lynch mob to be on my doorstep in moments to re-educate me!
Cheers, and thanks to the APOD editors & contributors for years & years of daily art for my desktop!

As far as I'm concerned you can.

Hello

This galaxy would have more than one MECO (BH) and millions in its arms. If it is smilar to the milky way.

I was just wondering what gives barred Spiral Galaxies their unique shape?

I don't know if this is answer you are looking for; but it gives a little insight to the shape of spiral galaxies. 8)
