• Most of these go against the typical Wikipedia convention to disambiguate articles by using parentheses after the article name, and discussion on WikiProject Astronomical objects has come to the view that the format should be Messier #. Many of the destination pages are redirects with more than one item in the history. Chaos syndrome 20:38, 25 July 2006 (UTC)

Distance

Per the SIMBAD 'distance' measurements entry, the following reference:

Crook, Aidan C.; Huchra, John P.; Martimbeau, Nathalie; Masters, Karen L.; Jarrett, Tom; Macri, Lucas M. (2007). "Groups of Galaxies in the Two Micron All Sky Redshift Survey". The Astrophysical Journal. 655 (2): 79–813. Bibcode:2007ApJ...655..790C. doi:10.1086/510201. {{cite journal}}: Unknown parameter |month= ignored (help)CS1 maint: multiple names: authors list (link)

gives a distance estimate of about 20 mpc (65 mly) rather than 55 mly.—RJH (talk) 18:10, 16 May 2010 (UTC)

Is this sentence too long to be readable?

"As usual on spiral galaxies of the Virgo Cluster, in the rest of the disk both star formation and neutral hydrogen, of which M100 is deficient compared to isolated spiral galaxies of similar Hubble type, are truncated within the galaxy's disk, which is caused by interactions with the intracluster medium of Virgo." Unmismoobjetivo (talk) 06:16, 20 May 2020 (UTC)

Yes! The comparison between M100 and Hubble type galaxies is wedged into a sentence about star formation regions. The sentence is ambiguous WRT which is deficient, star formation or neutral hydrogen. — Preceding unsigned comment added by Targa86 (talk • contribs) 19:07, 4 March 2021 (UTC)
