Cleaned up refs to R136 and R136a
There was much material in the article relating to R136 rather than R136a which was presented as being related to R136a. I explained the difference between these two: R136a (a compact star cluster) is a component of R136 (a super star cluster), gave a ref for this, and clarified the refs. I also deleted the star chart for R136a, since this article is about R136. If anyone can put in the star chart for R136, NOT R136a, please do so. I overlapped on an edit. The other edit maintained the confusion between R136 and R136a, and also some confusion over the status of R136 from an earlier ref which does not exist in the later references I added, so I replaced it with my edit. Please don't take this as a revert war. Please discuss on the talk page here. There was so much difference between the two edits I could not see how to combine them in a coherent way. I am happy to discuss this further on the talk page with all concerned. Puzl bustr (talk) 14:26, 25 October 2009 (UTC)
 * My edit was merely to request a citation for the dubious distance inside the infobox. I did not notice that it was specific to R136a. I support your removal of my edit with that infobox (I did not see any chart), but in case anyone feels strongly that it should return here it is on the right (minus unknown data). I read through some of the Massey paper and some of Alex de Cotter's 1998 paper. From those I made this crude crop of an NGC 2070 image, added some star labels and added that to the article in lieu of a chart. There is a more detailed chart in the Massey paper but I feel that might be copyright reserved. I then sorted the See also, References and Further reading sections. I think the reference style is Ok. -84user (talk) 23:38, 25 October 2009 (UTC)
 * A big improvement, good job. Picture clarifies things and refs look good. Puzl bustr (talk) 16:03, 26 October 2009 (UTC)

More clean-up
Changed all my references to ADSABS ones so it is coherent and chased up all the dates, URLs, etc I could. Added a simple description of R136. Puzl bustr (talk) 16:44, 25 October 2009 (UTC)
 * Everything seems OK, checking the references. I made away with one irrelevant, making an analysis of NGC 3603, scarcely mentioning R1360 at all. ... said: Rursus ( m bork³ ) 09:30, 27 October 2009 (UTC)

The R
The "R" in the R136:es seems to have a counterpart "RMC" in SIMBAD, which says that it stands for ''Radcliffe obs. Magellanic Cloud'', probably Radcliffe Observatory, probably meaning the R catalogue is earlier than 1934, and that SIMBAD have decided to rename all R objects to RMC. SIMBAD says "Avoid the usage of R, prefer RMC". Since Wikipedia just follows the rest of the herd, I have to take a look on internet, to see what name is legio. ... said: Rursus ( m bork³ ) 08:00, 27 October 2009 (UTC)
 * References for RMC 136b reveals that the astronomers aren't heeding SIMBAD:s recommendations (yet). ... said: Rursus ( m bork³ ) 08:08, 27 October 2009 (UTC)

removed white space
I deleted the clear after the picture before the white space to get rid of the white space. Puzl bustr (talk) 16:52, 28 October 2009 (UTC)

Massive star R136a1
One of the stars in this group has a mass of 300 solar masses and is twice as massive as any other measured star; this is not mentioned in the article, I'm reluctant to edit the article myself as I don't really know the details, only found out the information from BBC news, see http://www.bbc.co.uk/news/science-environment-10707416 —Preceding unsigned comment added by Mandolin666 (talk • contribs) 12:28, 21 July 2010 (UTC)

Much more massive?
Lots of recent coverage on this saying that the central star is much more massive:. Should be added. Fig (talk) 16:14, 21 July 2010 (UTC)


 * The correct article to cite is The R136 star cluster hosts several stars whose individual masses greatly exceed the accepted 150 Msun stellar mass limit (though the MNRAS article should be cited directly when published). --Keflavich (talk) 21:44, 21 July 2010 (UTC)

Clarification
"burning at 55-60,000 K". Shouldn't that be "with a surface temperature of 55-60,000 K"? Burning takes place in the core of the star, at millions of degrees Kelvin. --Mortense (talk) 15:03, 5 July 2011 (UTC)

File:R136 HST 2009-12-15.jpg to appear as POTD soon
Hello! This is a note to let the editors of this article know that File:R136 HST 2009-12-15.jpg will be appearing as picture of the day on July 22, 2011. You can view and edit the POTD blurb at Template:POTD/2011-07-22. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks!  howcheng  {chat} 16:49, 21 July 2011 (UTC)

Composite cluster
According to some recent news, R136 is a composite star cluster caused by two clusters merging together... -- 76.65.128.252 (talk) 13:08, 17 August 2012 (UTC)
