New Hubble Scheme
edit
I found another Hubble chart that might look more interesting on the site. -- Hurricane Devon (Talk), September 20, 2005
- Well, in my highly biased (I made the old graphic) opinion: I like the idea of having images of real galaxies on the chart, but I think his schematics are not very good. I tried to convey realistic shapes and differentiate between the bulge, bar and arms using color. Anyway, the image could definitely stand some improvement, so maybe there's an even better compromise. -- Xerxes 23:40, 20 September 2005 (UTC)

Sites should be merged. Same exact topic, and many users would benefit from consolidation of info. for research purposes.----sjenkins
Re-write and move from galaxy morphological classification
editAfter a major re-write, the Hubble sequence was getting too long to be just a section of the main article, so I moved it back here and left a summary under galaxy morphological classification. See the discussion here. Cosmo0 15:35, 15 September 2007 (UTC)
Date
editThe original article gave the date of Hubble's publication of his scheme as 1925. All the references I've seen attribute it to his 1936 book "Realm of the Nebulae", so that's what I've put. If anyone knows of an earlier reference, please update it in the article. Cosmo0 13:24, 17 September 2007 (UTC)

Diagram
editThe reference for the diagram should be James Jeans (1928), Astronomy and Cosmogony, page 332). Originally the diagram is rotated by 90 degrees. Hobbema (talk) 12:13, 17 February 2023 (UTC)
