Distance estimates[edit]

The two most commonly-cited distance estimates seem to be ~1.7 kpc (originating here) and ~2.6 kpc (originating here). Thoughts on which one to include? Will the template allow for both? --71.59.14.12 (talk) 15:04, 12 September 2017 (UTC)[reply]

RfC: Advertizement/petition[edit]

The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.


The "Madokami Nebula" stuff seems to be some kind of advertizement for a "petition" to IAU to change the name of the nebula. First:

  • IAU has no name list for nebulae, secondly,
  • the ones using Wikipedia to advertize petitions are violating the rules of Wikipedia, especially WP:NOTADVOCATE, especially not an area for advocacy, propaganda, or recruitment of any kind.

I'm going to investigate on how to solve this problem, if a Wikipedia:Requests for comment or a Wikipedia:Administrators' noticeboard/Incidents is needed to block the page from anon IP edits, or what formal action is to be taken. I'm letting this "Madokami Nebula" stuff stand for other editors to examine and take action, but it is a violation of Wikipedia rules. Rursus dixit. (mbork3!) 08:42, 23 February 2013 (UTC)[reply]

RfC/Request for comment: I don't know how this is to be solved, how is it? Rursus dixit. (mbork3!) 08:56, 23 February 2013 (UTC)[reply]
Agreed, the petition is dumb and the whole thing is likely to be ancient history by next year. Still, when it first showed up I decided just to reword it since it actually something that is happening and it is about the nebula. I was going to give it a few months and then most likely get rid of it. If we decide to get rid of it immediately, then I won't shed any tears. Lithopsian (talk) 19:24, 23 February 2013 (UTC)[reply]
  • Where's the dispute that the RFC is supposed to resolve? RFC's are not to be used unless there's something that can't normally be resolved by regular means. If noone is fighting or warring to keep it, then be WP:BOLD and delete it. No need for an RFC. — raekyt 03:51, 3 March 2013 (UTC)[reply]

Hello! This is a note to let the editors of this article know that File:EmissionNebula NGC6357.jpg will be appearing as picture of the day on April 16, 2014. You can view and edit the POTD blurb at Template:POTD/2014-04-16. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 00:34, 30 March 2014 (UTC)[reply]

NGC 6357
The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357, which extends one degree on the sky in the direction of the constellation Scorpius. Part of the nebula is ionised by the youngest (bluest) heavy stars in Pismis 24. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The brightest point of light above the centre of this image is Pismis 24-1, once thought to be the most massive known star but now known to be a binary system.Photograph: HST/NASA/ESA

NGC 6357

NGC 6357 is a diffuse nebula in the constellation Scorpius. This composite image of the nebula contains X-ray data from the Chandra X-ray Observatory and the ROSAT telescope (purple), infrared data from the Spitzer Space Telescope (orange), and optical data from the SuperCosmos Sky Survey (blue). Radiation from hot, young stars is energizing the cooler gas in the clouds that surround them. Often known as the Lobster Nebula, the astronomical object has also been termed the Madokami Nebula by fans of the anime Madoka Magica due to its supposed resemblance to the main character. Scientists at the Midcourse Space Experiment prefer the name War and Peace Nebula, because the bright, western part resembles a dove, while the eastern part looks like a skull in infrared images.
