NGC 891

note: the thumbnail for NGC 891 is a picture of the wrong galaxy (click through to the main article for this galaxy to see what it really looks like) — Preceding unsigned comment added by 75.119.233.130 (talk) 04:19, 24 February 2012 (UTC)

Distance removal

I removed the columns with the distances for several reasons:

• Many of the numbers were unreferenced.
• Many of the referenced numbers came from bogus references, including amateur astronomy websites. In particular, the seds.org website is unreliable.
• Extragalactic distances are very uncertain; they are difficult to measure or to calculate with precision. Even the NASA/IPAC Extragalactic Database has problems. For example, compare their measurement for the distance to the Sombrero Galaxy with what astronomers have measured (as can be found in the references in the Wikipedia article on the Sombrero Galaxy).
• Formal distances have not been measured to most spiral galaxies. As noted in the example with the Sombrero Galaxy, applying the Hubble law is tricky (given the presence of the Virgo Cluster), so calculations of the distance based on redshift are inappropriate.

Please do not add distances back to this article. At the very least, discuss the situation with me before doing so. Dr. Submillimeter 21:54, 4 January 2007 (UTC)

Dr.Submm quit Wikipedia, so that message no longer applies. 70.29.213.241 (talk) 13:12, 10 April 2009 (UTC)

I'd like to have distance information even if some data is not accurate. Yelizariev (talk) 12:20, 23 August 2020 (UTC)

Can I suggest inclusion of NGC 1672 as a Spiral Galaxy

NGC 1672 is a Barred Spiral Galaxy much like NGC 1300, in fact NGC 1672 is refered to as The Barred Galaxy. NGC 1300 is included on this list.

The general Description for NGC 1672:

The center of the galaxy contains a high surface brightness bar, and four filament-like spiral arms extend outward from the ends of this bar. The spiral arms are asymmetric; one of the arms in the northeast part of the disk is significantly brighter than its counterpart on the other side. The spiral arms also contain numerous star formation regions, some of which may be as large as 4′′

I am not as experienced as of yet to change these things myself, particularly when doing an addition to a Boxed Graph. Can someone make the addition of NGC 1672 to this list. This omission is an error. Thanks!

Why not the large page?

Are all of these in the main list List of galaxies? I suggest expanding List of galaxies with this info.121.166.132.237 (talk) 09:35, 10 January 2016 (UTC)

That makes no sense. This page is for spiral galaxies, not all galaxies, so the "large page" is not specialized for spirals, so many of these spirals would not appear there at all. Rather, we should expand this page with the sections of the "large list" like most distant, least distant, most massive, least massive sections. -- 67.70.35.17 (talk) 08:50, 19 August 2017 (UTC)
