| A summary of this article appears in Galaxy. |
"S" means lenticular ...
I'm not really an expert on the subject, but I'm gonna go out on a limb and say that "S" is short for 'spiral', not 'lenticular'. - Che Nuevara: 20:53, 25 April 2006 (UTC)
- That's true, S does mean Spiral. However E9, S0, SA0, SB0, SAB0 mean "lenticular". Lenticulars are spirals without arms, more or less. 132.205.93.90 18:58, 24 May 2006 (UTC)
Sites should be merged. Same exact topic, and many users would benefit from consolidation of info. for research purposes.----sjenkins
Andromeda Galaxy classification?
Quote from this article: "The Milky Way Galaxy is now believed to be an SBb galaxy; previously, it was thought to be Sb like its giant companion, the Andromeda Galaxy." I'm not an astronomer... but the Andromeda Galaxy is described as a barred spiral galaxy in its Misplaced Pages article so wouldn't that make the Andromeda Galaxy an SBb and not an Sb? 65.31.132.187 07:23, 22 August 2006 (UTC)
- The Andromeda Galaxy is apparently a complicated case. The galaxy contains a bar that was only identified recently (in an article currently only in preprint form), but most people would think that it is unbarred. References to it in this article should possibly be removed. GeorgeJBendo 21:17, 15 November 2006 (UTC)
Morphology not just for galaxies
The term morphology in astronomy is used to describe the shape of any object, though it's usually used for a point source surrounded by extended emission. It is particularly important in the description of planetary and protoplanetary nebulae and dust ejections around other stars like Eta Carinae. Anyone have any idea where to get refs for this, though? --Keflavich 21:30, 12 May 2007 (UTC)
- While morphology may be relevant in other parts of astronomy, this is an article about galaxy morphology. I suggest creating another article about morphology in other objects and linking to it from this page in the "See also" section.
- (I also did not understand the comment about how morphology is usually applied to point sources with extended emission. I usually see the term "morphology" applied to galaxies, but I may be biased because I am an extragalactic astronomer.) Dr. Submillimeter 07:32, 14 May 2007 (UTC)
