Talk:Molecular cloud

Experiments
I belive that the experiments being described is too specialized to belong in the main page, unless all similar experiments being carried on were included too. Even if relevant to the problem (which I can not evaluate, but the author probably can), I don't expect it to be the whole story on molecular clouds chemistry. --AN

Some effort should be made to rationalise this page, the Dark_nebula page and the HII_regions page. Fig 23:34, 7 February 2006 (UTC)

Picture
Am I the only one who has noticed the acute resemblance of that molecular cloud to a giant offensive gesture? If so why is it still there? —Preceding unsigned comment added by 81.131.57.36 (talk) 18:54, 17 December 2007 (UTC)

I was kinda wondering that myself. Is this some kind of passive-aggressive gesture from some alien? —Preceding unsigned comment added by 71.2.235.98 (talk) 19:16, 20 February 2008 (UTC)
 * When I saw it at first time, I thought that it is vandalism, like someone has inserted a potatochopped picture. But when I realized that it is a real pic, I laughed my ass off. 89.146.64.77 (talk) 19:21, 23 May 2008 (UTC)

If this is what you see...then you obviously have nothing better to do with your time. It is just a cloud formation and NOTHING MORE! GROW UP! —Preceding unsigned comment added by 68.228.255.126 (talk) 23:30, 31 May 2008 (UTC)

Why would you take it down? It's the most funny thing the Hubble has ever discovered. —Preceding unsigned comment added by 142.167.77.132 (talk) 01:44, 3 June 2008 (UTC)

No reason to censor nature. ;) I really hope someone names this "The F Cloud".--Ecnassianer (talk) 22:28, 6 October 2009 (UTC)

distribution in space
the article speaks only about molecular clouds and "star nurseries" within galaxies... am I right in assuming that there are no such nurseries in the intergalactic space??? and generally: where are they most likely localized? more towards the centers of galaxies, or more towards the fringes? or can they be everywhere, so we could have star formation regions outside of galaxies feeding them with stars so to speak?? --HilmarHansWerner (talk) 22:28, 26 October 2011 (UTC)

GMC size inconsistency
The section on Giant Molecular Clouds says "A vast assemblage of molecular gas with a mass of 104–106 times the mass of the Sun" and later "(...) it contains 100,000 to 10,000,000 times as much mass as the Sun."

Which of these is true? Fluorhydric (talk) 11:21, 3 September 2012 (UTC)
 * Either or both. Particularly the lower limit is largely a matter of definition. I found a reference and cleaned it up a bit. —Alex (ASHill &#124; talk &#124; contribs) 23:28, 3 September 2012 (UTC)

Molecular cloud matter
In what process molecular hydrogen has formed in interstellar space? Bond formation energy must be dissipated to allow hydrogen atoms combine together. Some link to known hypothesis concerned might be appropriate here. — Preceding unsigned comment added by 176.59.134.200 (talk) 06:13, 24 August 2019 (UTC)
